Brief Summary of Minutes

Kevin Jensen (W6 Chair)

Kevin welcomed everyone, particularly, Marilyn Warburton who was recently hired as the Research Leader at the Western Regional Plant Introduction Station (WRPIS). This was followed by a brief introduction of everyone since there were many new state representatives present. The agenda had changed significantly from previous meeting with the State Reports in the morning followed by a working meeting in the afternoon to discuss ways that the W6 RTAC can help meet current and foreseen needs of W6 Regional Multistate Project.

Scot Hulbert (WSU W6 Administrative Advisor)

Scot provided a report, remarks, and discussed budget

5-year project was approved (2022-2026) – thanks to everyone who worked on it.

Report was given on the new construction of the 100,000 sq ft USDA ARS building on the WSU campus in Pullman, WA. Concerns were raised over possible cost overruns (~$17,000,000) in the construction, which will likely result in the sharing of equipment and controlled environmental rooms. Stakeholders, including Washington State University, are speaking with their representatives in Congress to get additional funding to complete the project.

Wendy Powers would assume Dean of Agriculture August 15, 2022.

Concerns over increased wages and flat budgets were discussed, in the context of the W6 multistate project and personnel supported by it.

2023 budget was presented by Scot Hulbert which requested a $49,352 increase in W6 funding. The W6 budget routinely covers 6 full-time people, wages for summer help and some supplies. A concern discussed was that, due to increased wage requirements, project might have to do with less workers.

Shaun Mehlenbacher made the motion to approve the budget

Charlie Brummer seconded the motion

Discussion … State Representatives need to visit with their respective Experiment Station Directors to support this and other increases to the W6 program.

W6 2023 proposed budget was approve unanimously.

Peter Bretting (USDA ARS National Programs Leader)

Peter Bretting presented slides entitled: The National Plant Germplasm System: 2022 Status, Prospects, and Challenges. A map of the gene banks nationwide was presented. NPGS accessions have increased over the last several years up to 600,092 in 2021. From 2018 to 2021, the number of accessions is not increasing significantly. The big increase was associated with the Seeds of Success program submitting their native plant collections. NPGS distributed 219,000 accessions in 2021 up 14% from 2020. During the Pandemic, some genebanks are finding it difficult to hire temporary, often student labor, because of the low unemployment rate and demographic changes. As in the past, most of these distributions are to public research institutions (e.g., Land-Grant and USDA) with about 1/3 for private usage. Two thirds to three quarters of distributions are domestic and the remainder international. Acknowledged the passing of David Spooner, long-time USDA ARS successful plant geneticist/breeder.

Budget wise, NPGS saw a $2.5 million increase in its 2021. Specifically, the increases went to Small Grains PGR, Aberdeen, ID ($190,000); Vaccinium PGR, Corvallis, OR ($150,000); Hemp PGR, Geneva, NY ($1.35 million); and Pecan PGR, College Station, TX ($400,000). Challenges facing the NPGS include:

Expanding the NPGS operational capacity and infrastructure to reduce PGR management backlogs and meet increased demand for PGR and associated information.

Increased operation costs (labor, inputs, overall inflation, etc.). Reference the Economic Research Service (ERS) Amer Waves online magazine article on “Investment in U.S. Public Agricultural Research and Development Has Gallen by a Third Over Past Two Decades, Lags Major Trade Competitors”.

NPGS personnel transitions – hiring, training, etc. In the next few years over 1/3 of the germplasm managers will likely retire.

Developing and applying cryopreservation and/or in vitro conservation methods for clonal and some seed PGR.

BMPs and procedures for managing accessions (and breeding stocks) with increased diversity of GE traits in more crops, the occurrence of adventitious presence (AP, and the products of gene editing.

Acquiring and conserving additional PGR, especially of crop wild relatives.

Christian Tobias (USDA NIFA Representative)

Christian is representing the Institute of Food Production and Sustainability with programmatic authority over Plant Breeding with over $2 million available and will be taking over the potato breeding research programs within the next year. The agency lost ~80% of their work force in the move to Kansas City, MO with 80% of the time teleworking. Encouraged conventional plant breeding for new cultivars with a deadline of September 2^0,2022 for submission.

2021 W6 RTAC meeting minutes, changes, discussion, and approval

The virtual floor was opened for any discussions, questions, or comments about the 2021 meeting minutes. Brian Irish reported identifying two to three grammatical corrections. Those suggestions were sent to Ian Ray, past W6 RTAC Chair for correction. Ian Ray moved that the minutes be approved, and Kevin Jensen seconded the motion. The motion was approved unanimously.

Budget

The total federal ARS budget for the PGITRU was $3,257,476 and includes the budgets for the Pullman-based germplasm ($2,539,778), the Prosser-based temperate-adapted forage legume germplasm ($275,939) and alfalfa genetics research ($441,759) projects. After indirect costs are assessed, net balance was $2,903,622 with $2,563,900 dedicated to salaries and the remainder for supplies, equipment, repairs, and extramural agreements. The discretionary dollar amount per SY (7 in the Unit in 2020), an indicator of the financial health of the Unit, was $36,228; an improvement from last year due to the abolishment of one of the SY positions. The ‘in kind’ support from the W6 Western Regional Multistate Research Project, through Washington State University, was $477,301.

W6 RTAC Business Meeting

RTAC discussion on how we can make the W6 project sustainable.

Stakeholder group – currently WRPIS/W6 does not have a stakeholder group. Discussion was had on who should be (commodity groups) on the stakeholder committee. Besides research guidance, one of the main reasons for a stakeholder group is to advocate on the WRPIS’s behalf in efforts to remain fiscally sustainable. Possible commodity groups mentioned include alfalfa, American Seed Trade Association, sugar beets, legumes, and The Plant Conservation Alliance.

Each State Representative was tasked with sending some potential stakeholder names to Marilyn before the end of the year. It was decided that the W6 RTAC Chair would invite several stakeholders to the next W6 RTAC meeting in 2023.

Discussion on how to improve ways to collect impact data – One advantage of working with a good stakeholder group is to be able to document the impact that germplasm distributions from the NPGS are having. The W6 RTAC does a good job reporting on current year’s seed distribution and potential use, but there is little follow up in years to come. How can we better hold germplasm users accountable for the germplasm received? In efforts to document impacts, state representatives were asked to contact 2018 germplasm users for publications and impact. Peter Bretting indicated that in the past he had used the ERS to estimate economic impact of NPGS.

Possibly looking on the national level to use Artificial Intelligence to collect data – using a set of key words to search publications.

Could USDA NIFA funded proposals utilizing NPGS germplasm be require to report impacts of the germplasm?

White Paper Development – Demonstration of economic impact.
- Private sector – statement of support (look to commodity groups)
- Public sector (Land Grant U., USDA, non-profit, etc.)
- State Representative Specialty (i.e., Kevin Jensen – grasses)
- Utilize Crop Science Sub-Divisions

It was agreed upon that the state representatives would develop a 1-to-2-page document in their area of specialty, describing the economic impact of NPGS collections. A good example is the “Use of Plant Introduction or Cultivar Development Part I and II”. This is due by December 20^th, 2022.

Accomplishments

Outputs: <ul> <li>A total of 36 publications, including one durum wheat cultivar and five bean germplasm releases, were reported for FY 2021. This includes a book entitled “The Alfalfa Genome” (co-edited by Long-Xi Yu) published by Springer in 2021. It contains 16 chapters covering history, classical and molecular breeding as well as advances in genomics associated with the alfalfa crop.</li> </ul> <ul> <ul> <li>Chickpea (Cicer arietinum), lentil (Lens culinaris) and pea (Pisum sativum) genetic resources were screened for resistance to the pea aphid (Acrythosiphon pisum). The chickpea (Cicer arietinum) resources were screened for resistance to Pythium seed rot caused by Pythium ultimum.  Out of 188 lentil accessions screened for resistance to the pea aphid, twenty were determined to be resistant and fifteen candidate genes were identified as being associated with the resistance.  Out of 301 pea accessions screened for resistance to the pea aphid, 48 were determined to be resistant and seventeen candidate genes were identified as being associated with the resistance.</li> </ul> </ul>   <ul> <li>Activities:</li> </ul> <ul> <ul> <li>The Phaseolus program developed a near-infrared spectroscopy (NIR) calibration curve for bean seed protein, which was used to measure the seed protein of the BeanCap genomewide association panel. With this data and the sequencing data publicly available for the BeanCap population, protein levels can be associated with genomic locations and genes. This will lead to information on genes for future marker aided improvement of this important trait.</li> <li>The Cool Season Food Legume program published a collaborative pea evaluation study promoting genomic selection's potential. A set of 482 pea accessions genotyped with 30,600 SNP markers and phenotyped for seed yield and yield-related components highlighted the best genomic prediction model. This was then used to evaluate all USDA pea accessions that were genotyped but not phenotyped, sparing the unit the expense of having to phenotype.</li> <li>A collaborative team led by Long-Xi Yu mapped genetic loci associated with drought and high salinity, two abiotic stressors affecting alfalfa production worldwide. Associated genes were identified that can be used for gene pyramiding, gene editing and developing markers for marker-assisted selection for drought and salt tolerant alfalfa once they are validated.</li> <li>All alfalfa and wild relative germplasm (Medicago spp.) were screened for disease reaction to Phoma medicaginis, the causal agent of spring blackstem and leaf spot of alfalfa.</li> <li>Phenotypic data for resistance to Phytophthora megasperma were collected from 150 seedlings each of 250 half-sib families derived from an elite NMSU breeding population. The study was repeated twice. GWAS analyses of these data, in conjunction with >10,000 DNA markers, are being conducted to identify alfalfa genome regions that are associated with P. megasperma resistance. The data are also being analyzed using multiple genomic selection models to identify superior models for accelerating improvement of alfalfa resistance to this disease.</li> </ul> </ul>   <ul> <li>Milestones: <ul> <li>Washington State University’s Johnson Hall, which housed 8 offices and 4 laboratories used by WRPIS staff, has been vacated prior to the demolition of the building and the construction of the new Plant Biosciences Building. This new building will be funded by the USDA ARS, and house USDA and WSU Units/Departments, faculty offices and laboratories. It will house Pullman-based WRPIS scientific and technical staff and include six modern Unit-shared laboratory spaces. The new building will be built on what is the current Johnson Hall footprint. Johnson Hall is now vacated, and all WRPIS moved into adjacent (and smaller) Clark Hall until the new building is finished. Johnson Hall is scheduled for demolition in January 2023, following asbestos abatement. The new building is scheduled to be completed in l2026 and WRPIS will occupy new facilities at that time.</li> </ul> </li> </ul>

Day 1: July 11, 2023

8:00 am: The meeting started by introduction of meeting attendees.

8:05 am: The attendees were asked regarding any issues with the current proposed agenda for the meeting: No issues were raised by the meeting attendees.

8:06 am: The USDA leadership reports - Peter Bretting

Peter Bretting presented the annual update of the national centers and the home-office work continuous situation. Peter acknowledged the new state representatives, thanked them for serving on the W6-RTAC advisory committee, and emphasized on the importance of this committee.

The presentation emphasized the large number of genebanks in Western Region and the large number of accessions they preserve. Also, that the genebanks they cover most of the growing regions in the US. The location of the genebanks in association with the location of different land-grant universities in the Western Region for over 80 years.

Figure (1): Map of the USDA National Plant Germplasm System (NPGS) locations nationwide (See graph in Attachments)

The location is part of the connection between genebanks, land-grant universities, USDA, and agricultural producers. This connection is important for the long-term care of the germplasm collections. No one institution or organization can do it alone. As of December 2022, over six hundred and five thousand accessions are held by the NPGS. The growth rate over the last few years has been relatively modest, due to the focus on taking care of the existing collection.

There's also been some new collections that have been started in the last few years, including coffee and hemp. The average number of samples distributed annually is between 225,000-250,000. The distribution was down in 2020 due to the COVID Pandemic and currently distributions are back to normal as before pre-Pandemic.

Figure (2): The Demand for NPGS Germplasm 2013-2022 (See graph in Attachments)

The number or percentage of the germplasm that’s distributed to the US depending upon the crop is usually between two-thirds to three-quarters, and that really depends on international interest in the crop. In the US, the largest recipients are the faculty and students at land-grant universities, then public sector organization, such as ARS. Depending upon the crop, two-thirds, or three-quarters of the domestic distributions are for the public sector, and the remainder are to the private sector. Again, a this is a long-term average not a quota and not surprisingly those crops where there’s a very strong private sector support are the ones with the lowest public sector distribution.

Regarding the budget: The ARS portion of the NPGS has been growing slowly over the last few years, just over 50 million dollars. At present the NPGS is grateful for this level of support. However, the purchasing power of the dollar in comparison to the budget increase, the situation looks less rosy. The key challenges are expanding the operational capacity and the infrastructure to meet the backlogs in some of our management operations. Additionally, the operational costs, laborers, more expensive inputs, fuel, and equipment (just the overall inflation).

An article by an Economic Research Service member stated that the investment in US public sector in real dollars has fallen by a third over the last twenty years. The NPGS budget is following same trend, with a generational turnover, as baby boomers continue to retire, and the need to hire new staff. Hiring new staff members come with challenges of training them in order to provide the same high-quality services expected from the NPGS and for different crops based on the storage conditions (liquid nitrogen, in-vitro, tissue culture, propagated materials in the form of buds, embryos, etc. Efficiency in the process and having more information about the accessions, will make them more valuable for breeding, research, and production.

Rehiring of vacant positions, at the genebanks, is on-going but slow. Some have been vacant for over 4 years now. Training new hires is led by ARS and NIFA grant to design and develop a training program for plant genetic source management. Due to the large-scale international interest in such training, it was decided in 2018 it really needed to be distance learning/online. Currently, there is a three module, three credit course at Colorado State University. Additionally, climate change and its impact on current crops and varieties productivity and the need for more adapted crops and varieties. Recent research funds been focusing on commodity crops, such as pecan, coffee, and pulses. A question was raised from the audience regarding the expectations for the coming annual budget as its expected to be released sometime in September or October 2023.

8:33 am: Tara McHugh, Area director for the Pacific West Area

Tara McHugh started her presentation by thanking Kevin, Marilyn, and everyone contributed to putting the meeting together. Thanking Peter for the thorough detailed presentation.

8:37 am: Kevin, as the Acting Associate Area Director, was asked to provide a presentation.

Kevin gave an overview of the area, including that there are 21 locations spread across eight States (Arizona, California, Hawaii, Idaho, Nevada, Oregon, Utah, Washington) and many of those are not located or co-located with land-grant universities. There are 49 research units, there are 401 Ph.D. Scientists, and approximately 1,400 employees. There’s a new shellfish breeding program in Newport, OR. The research includes crops, animals, human nutrition, and program utilization and being around different areas show the impressing work put there to keep the centers running. The relations with the stakeholder (internal and external) are crucial to keep the support continuous. Focusing on the stakeholders need and their input is important for this work to continue and thrive.

Congressional appropriation (233 million annually) and soft funds of 22 million (10% of the total budget) and are the source of funds for the centers. The soft funds have been helpful in supporting post-doctorate associates and other positions. ARS are encouraged to apply for soft funds. The leadership is committed to fulfill the stakeholders needs. Anna Murphy of the Beet Sugar Development Foundation asked about the weed resistance budget. Tara Hughes mentioned that the fund is being used to fund some positions to work on these issues.

8:45 am. Jessica Shade and Christian Tobias from the USDA NIFA Division of Plant Systems Production introduced themselves and Jessica started the presentation outlines including NIFA programs updates, plant breeding roadmap, and some specific funding opportunities. Jessica is on the Urban Indoor and Emerging Ag Program team, the Specialty Crop Research Initiative team, and the Data Science for Ag Systems team, while Christian AFRI programs, Breeding for Agricultural Production, and Plant Breeding or Conventional Plant Breeding for Cultivars Development and on some non-AFRI Programs.

The available funding programs are for food and Ag-sciences related topics. NIFA goal and mission of investing in and advancing agricultural research, education, and extension to solve societal challenges, and the vision of transformative discoveries, education, and engagement to address our challenges. NIFA covers a broad array of program areas. The Ag Food Research Initiative has a total funding of 455 million dollars for its multiple programs, as well as other competitive grants outside of AFRI, like the SCRI program, which gets 80 million dollars annually.

Jessica provided information about recent leadership changes within NIFA. A new director (Manjit Misra) was appointed on May 6, 2023. Dionne Toombs is the Associate Director.

They also updated the committee regarding the Grants Modernization Initiative, which is focusing on updating the outdated current grant management system. The new system is based on the NIH system and there are some issues might cause delays. The USDA Plant Breeding Roadmap 2021-2026, which was based off extensive stakeholder engagement and needs and focused USDA plant breeding priorities.

The roadmap has a focus on crops and markets that impact public pulse of ours and ensure genetic resources for specialty crops that meet the economic, cultural, and nutritional needs of Americans, and it includes the entire breeding cycle in a very integrated way, and it's focused on developing and modeling novel and optimal methods for breeding. And it connects education and workforce development programs with startup and established businesses with a focus on building human and decision-making skills and on simulation, modeling, and forecasting future plant breeding skills.

It also focuses on developing and scaling up new methods for things like rapid development of plant breeding, education programs, faculty and research professionals to meet future plant breeding needs and increase access to program participation among underserved communities. It also builds out a plant-breeding emphasis and stakeholder feedback integration for crops that are important to tribal groups and underserved communities.

More information about the new roadmap can be found on at the following link (http://www.usda.gov/topics/plants) and provide feedbacks to (PBRoadmapComments@usda.gov).

Christian highlighted some recent funding from different programs related to the W6 committee, including available funds, crop specific information, and it did not include funding from programs for post-doctoral fellowships, or plant protection or plant production systems area. The presentation included an overview of AFRI and non-AFRI programs and included information on the most beneficial points of focus (e.g., deadline, letter of intent, program priorities.

There are three requests for applications associated with the AFRI program, the Foundation and Applied Science, Education and Workforce Development, and Sustainable AgSystems.

The AFRI SAS (Sustainable Agricultural Systems) RFA was published in February. These are integrated grants. There is one program emphasis on mitigating methane emission in ruminants and other than that there is a call to address areas that are administration priorities (such as climate change, the bio-economy, and nutrition security). These, again, can address all six AFRI farm bill areas, and they are expected to implement a systems-based approach, including research, education, and extension. There are other programs listed but application deadline has passed for this year. Programs vary in their requirements, including two-step application that include letter of intent, pre-proposal, and if invited, a full application to follow (e.g., SCRI). Other programs might be of interest including AFRI FAS with the below priorities and a link to previously held technical assistance webinar:

Figure (4): AFRI FAS priorities areas. (See graph in Attachments)

9:13 am: Kevin thanked the presenters and mentioned the last year minutes and the states reports for 2022 and what they are used for regarding the amount, use, benefits, and impact of germplasms requested from the genebanks.

9:15 am: California Report: Charlie Brummer

Charlie started the state report by thanking Brian Irish and all other curators at the genebanks for their outstanding and hard work in keeping the germplasm available and the importance of these germplasm for many funds and fulfillment of objectives, since they are not available commercially. Charlie also mentioned the importance of doing a better job at reporting to show how impactful this germplasm is in new cultivar development for various purposes, which could be the difference between getting or not getting grant awards. Charlie will be submitting the state report separately.

Kevin asked a question about the implication of the germplasm availability or lack of availability impact on the expected results of the work when it comes to the alfalfa or other crops in the industry. Some discussion was about viruses in sugar-beet and the difficulty in regenerating germplasm as it requires large isolation distances order to maintain genetic integrity. The requirements make it harder to produce more seeds for the local industry.

9:25 am: Idaho State Report: Joseph Kuhl:

Joseph gave a report for 2 years (2019 and 2022) set of orders form WRPIS. From Idaho requested about twenty orders for a total of 107 accessions. There was a total of 10 different groups placing the 20 orders, with 10 of them placed by private companies followed by 2 universities, 2 private individuals, and 1 from a state agency. A total of ten emails were sent out to the groups. In these orders, the five companies placed half of the orders. Idaho State seed lab have placed 4 orders, and so they're requesting several different plant species as controls in their evaluation. Private company requests are for lines used in breeding programs.

Kevin asked about the responses from 2019 orders. Joe explained that the replies if, if any, were generally thanking the W6 genebanks for providing the lines, with no specific results or publications to report.

9:30 am: Montana State Report: Norman Weeden

There was 1 request with over 60 accessions of faba bean from Montana State. The research is for variety evaluation and development effort. The evaluation started last in the 2021 and it continuous for FY22. Most recent work on crops and varieties selection have been focusing on the selection for certain characteristics, including heat tolerance and disease resistance. Some new findings have been reported including the “Stay Green Intron” cotyledon color gene in dry peas and how it may or may not exist in other species and how important such characteristics for other species.

Figure (6): Results of the STAYGREEN Intron in dry peas species and sub-species (See graph in Attachments)

9:40 am: New Mexico State Report: Naveen Puppala

The report was compiled by Ian Ray. In FY22, there was 4 orders with 59 total accessions received. 70% of the orders were from the New Mexico State University, followed by the University of New Mexico with 27% and 3% was ordered by the Highlands University. The main purpose for the orders was for breeding and genetics, ecological uses, and field demonstrations.

9:45 am: Nevada State Report: Melinda Yerka

In FY22, four orders, for 57 accessions, were placed from the genebanks. 33.3% of the accessions were used in entomology, 19.3% in Taxonomy, and 47.4% in anthropology. Recently there was a reported published manuscript using NPGS plant materials. The University of Nevada affiliates are the most significant users of the NPGS system. Generally, the users are very happy with the materials quality, no recent release of any of the ordered materials. Responders gave detailed information about the purpose for the orders.

9:50-10:30 am Break

10:30 am: Oregon State Report: Shawn Mehlenbacher

The requested accessions were used for disease-resistance and yield selection. New variety of hazelnut will be released under the name “The Beast”. Allium accessions were ordered for research related to DADS (diallyl disulfide) analysis. This is an oil-soluble organosulfur compound found in garlic, tested for suppressing human non-small cell lung carcinoma. A Journal article was published with the Journal of Agricultural and Food Systems. The accessions were ordered by the University affiliates and USDA-ARS fellows. Members of the private (seed companies and nurseries) sector placed orders as well for identification purposes, field evaluation, seed increase, and other purposes. A variety of bean “Ruby Dwarf Horticultural” is currently growing for seed increase. Three journal articles were published.

10:55 am: Utah State Report: Kevin Jensen.

In 2022 there were four NPGS-W6 orders received from 3 individuals (3 from government agencies and 1 from the university). One of the points presented was regarding hybrid validity and other interesting information from the tested lines. Bad email addresses reduced the percentage of responses received.

Figure (7): Orders by NPGS site received in the state of Washington in 2019. (See graphs in Attachments)

11:05 am: Washington State Report: Per McCord

There were 130 requests in 2019, and we received responses from 42% of total emails sent, with 11 bad email addresses. There were a total of 8 publications, including a PhD thesis and a 1 non-referral publication. The accessions requests were placed for various reasons, including pest resistance, variety evaluation, gene-mapping, and other purposes. For 2022, there were 73 requests, with a total of 3,668 accessions received by various entities.

11:15 am: Alaska State Report:

Three individuals requested accession from the genebanks. Since the individuals were contacted but didn’t reply, a reminder email will be sent again, and the final report will be submitted via an email later. A question came up about climate change impacting the growing season in Alaska and how that will impact the future of crop production in the state.

11:25 am: Hawaii State Report: Amjad Ahmad

The report started by mentioning the importance of the NPGS W6 as a crucial resource for Hawaii, mainly due to limited options of breeding program focused on the state with its tropical/sub-tropical condition, the state micro-climates, and how having access to the accessions allowed for improved crop diversity and variety selection for the state. There was 1 request for accessions from the state in 2022 for forage crop seeds. The Hawaii (Big Island) Island is known for its livestock, but climate change and droughts cycles have impacted the availability of grass in sufficient amount. The request was from a private ranch to evaluate for faster growing grass for animal feed. The ranch owners were very pleased with the accessions they received and are very thankful for the genebanks.

11:35 am: Wyoming State Report: Donna Harris:

In 2022 there were four orders placed by individuals from the University of Wyoming with a total of 98 accession received. The accessions were used for research purposes in variety evaluation, bio-remediation, mapping of popping bean, studying genes related to far red light sensitivity.

In 2019 there were 8 orders for accessions and total of 51 accessions were received. The requests were mainly from the University and used for research purposes in variety evaluation, crop development, and demonstration/educational purposes.

11:45 am: Arizona State Report: Glenn Wright

In 2019 there were 10 orders mostly by state agencies and they were used for various purposes in research, genetics, demonstration, and variety evaluation. In 2022 there was 11orders and they were placed mostly by state agencies. There were 3 responses to the survey sent regarding the received accessions with general satisfaction.

A discussion among the meeting participants was initiated and ensured regarding ways to improve response rate from the germplasm recipients and better communication ways between the genebanks and the accessions recipients, especially when there are issues with an order (e.g., germination rates of seed).

11:55 am: ARS UPDATES:

NGRL Update: Gary Kinard

GRIN-Global database system had not been affected significantly with the Pandemic and over the past 3+ years, new functions have been introduced, including GRIN-U (https://grin-u.org/) as an open access site for education, training, and outreach information. There's also a companion YouTube-channel that houses some interesting cool, relatively short videos on a whole range of topics related to plant genetic resources. Karen Williams retired at the end of 2022 after 39 years of services at the ARS. However, Karen is coming back for 10-12 hours a week through an agreement to facilitate the transitioning until the new scientist in her role is more adequately trained. Peter Abrahamian will join NGRL as a Research Plant Pathologist.

New functions were added into GRIN-Global, including seasonal availability and the ability to request multiple form types (e.g., seed, cuttings, pollen, etc.) of an accession. These are mostly relevant to the clonal collections. New taxonomy regulations were incorporated during the search of images of plant parts, and others related to accessibility with the Americans with Disabilities Act (ADA) requirements. NGRL is also work on a request to allow orders from multiple genebanks to be processed as well.

NSGC Update: Harold Bockelman

The National Small Grains Collection (NSGC) is currently rehiring a vacant position to add into the small group of people at the NSGC. The team has a new research leader, Noelle Anglin, who is now working on potatoes and will be working part time with the NSGC. The NSGC has reached a milestone of 150,000 total accessions conserved this year. About 10,000 of those accessions are mapping populations and temporary accessions which are valuable for a period, as part of various research projects that were funded by NIFA and other organizations. There is a large collection of the small grains, and most are grown in Idaho. An exception is rice, which the Dale Bumpers Rice Research Center in Stuttgart, AR grow and evaluate. 37,000 accessions were distributed last year. A change in emphasis on the wild accessions through new projects by studying methods to validate accessions in terms of taxonomy and looking at ways to get viability data on the wild accessions.

NCGR-Corvallis Update: Lauri Reinhold

Figure (8) Total accessions and distribution line from the NCGR-Corvallis site 2011-2022. (See graph in Attachments)

NCGR-Davis Updates: Claire Heinitz

Claire Heinitz is the recently hired Research Leader for two units, the NCGR at Davis and NALPGRU-Parlier and gave updates for both locations. The NCGR-Davis maintains 14 different crops that are all Mediterranean adapted tree fruit crops and grapes. They are maintained as a fully clonal collection on ~70 acres of land that is leased from UC-Davis. The land ownership situation impacts the management decisions at the site. An irrigation well, serving about half of the research plot, was lost the summer before last, and the procurement process to drill a new well is on-going. Another well shared with UC-Davis also went down and around the same time. Drought issues in California and research plots are realities the unit is facing. Recently, there were two major retirements, and the positions are still vacant. The vacancies have caused overload on other employees and unit is relying on some stakeholder support. The NALPGRU-Parlier has a dual mission of serving as a service regeneration and backup site for many other NPGS sites in the system. It also has its own germplasm collections of emerging arid lands crops. The site has a collection of new or emerging crops, mostly with industrial uses. There are a few staff changes, including an interim curator, Daniel Packer from Washington State University. The vacancies have increased load on the technicians in doing more.

NLGRP Update: Gayle Volk

The USDA-ARS NLGRP has over 600,000 accessions representing over 2500 genera at 20 locations. The NLGRP serves as a safe secondary backup for the NPGS materials. 93% of the materials are seeds propagated and 7% are vegetative propagated materials. Fort Collins site have ~82% of the NPGS seeds accessions and ~15% of the clonal accessions backed up. Securing these accessions is a huge amount of work and labor due to the specific storing conditions needed to secure these materials. A GRIN-Global programmer, hired a few years ago, is working with both the seed and the clonal group to improve documentation process and standardizing information collection process. He is also working on to improve the GRIN-Global system interfaces. The updates will improve reporting process, materials condition, and materials availability. There was a mention on a new publication on safeguarding plant genetic resources during climate change. Updates on the new GRIN-U website and e-book chapter publications about genebanks and other topics through Colorado State University. Also, GRIN-U and YouTube-channel content and 1-credit classes provided by the Colorado State University regarding plant genetic resources conservation.

NCGR-Hilo: Tracie Matsumoto:

The site is one of 3 sites for tropical/subtropical crops (Florida, Puerto Rico, and Hawaii). The site has crops important for Hawaii Agriculture. There have been few retirements and new hires at the site recently. Coffee has been added to the germplasm collection with a new person studying at the University of Hawaii to become a curator. Lisa Keith a pathologist working on the new Macadamia quick decline disease and the coffee leaf rust that was first reported in Hawaii in 2020. Shortage in Rainbow Hybrid papaya seed is on-going in Hawaii and the effort working with the University of Hawaii to produce the hybrid seeds for local use. In collaboration with the genebanks in Florida, ‘Sharwil’ avocado varieties were approved for export from Hawaii to 13 US states. A new DNA Fingerprinting tool is being developed to ensure quality and detect contamination in avocado. Testing for the mild mosaic virus in cacao is ongoing and variety trials have been conducted statewide by the University of Hawaii faculty.

NCGR-Riverside: Robert Krueger

Robert Kreuger is the currently research leader at the Riverside genebank. The site is located at UC-Riverside campus. The site leases 2-acres owned by the USDA and utilizes 12,000 sq. ft of land owned by UC-Riverside. A new plant pathologist position that’s currently being recruited and a curator position to be recruited soon. The site depends on student workers, undergraduate student workers for a lot of the day-to-day activities. 90% of the activities are on citrus and 10% on date palms. Additional field sites are located at Irvine, which is in the coastal part of Southern California, and the other is a Thermal, CA which is in the low desert area. A long-term cryopreservation trial for Citrus spp. project with Fort Collins is on-going. 541 accessions were done out of 609 total, with some are pending viability assessment. When it comes to stakeholders, there are some institutional stakeholders, including commodity groups, research boards, Research and Development Foundation, and California Date Commission. There are domestic and international collaborating scientists and other national genebanks in genetic resource conservation programs.

*Unique accessions = 1,687.

LUNCH BREAK

2:00 pm: Scot Hulbert: Budget Updates

Participating remotely, Scot provided updates on the budget and funding sources, including the Farm Bill, NIFA, and others. Scot also brought up the possibility that WSU will be working under a new funding allocation model in the future, which could cause charges for space allocation in WSU buildings and fields. This would have big implications on the functioning and funding of the W-6 and Pullman genebank activities, so we will be watching this development closely. A discussion regarding the budget annual 3% increase percentage over the 5-year budget regarding current inflation rate ensued. After the discussion the budget was agreed to and approved by the committee.

2:10 pm: Naidu Rayapati:

The Director (Naidu Rayapati) of the Irrigated Agriculture Research and Extension Center (IAREC) in Prosser, WA, and hosting site for the annual meeting gave an overview of the host site (Prosser-IAREC) with close to 100-acres of research activities. It has 16 WSU faculty, 11 USDA-ARS, and 1 WSDA scientists. It has three research farms with close to 300 acres of land. It is one of the largest research centers within the WSU system. The center is equipped for all research and extension activities.

2:30 pm: Facilities Tour (only for onsite participants)

A tour of the W6 (Plant Germplasm Introduction and Testing Unit) USDA ARS local Prosser worksite programs facilities in Prosser was led. This included laboratories greenhouses and field sites for the two local programs led by Long-Xi Yu and Brian Irish.

4:30 pm:

Day 1 meeting adjourned.

Day 2, July 12, 2023

Research Presentations:

8:00 am: Charlie Brummer: Impact of NPGS on Alfalfa Cultivar Development

Historically, breeders talk about 9 historic introductions periods into the Americas. Some of these introductions were immediately added into the NPGS collection, while others, were not included immediately or never at all. Examples of these folks, Wendelin Grimm (1800s) and N.E. Hansen (1900s). Looking at the collection for both the purple and yellow flowers and how their availability in the NPGS system helping in the development of new cultivars. Old publications talk about all the early varieties of alfalfa. Then it was very clear where everything came from between the 50s and 70s. Registration of the early varieties were published, including Washoe, Florida 66, WL 214, and Desert. Indian germplasm was used in developing varieties as well. Currently, we know less and less about the role of NPGS germplasm in cultivars development because pedigrees are not a requirement in releases. Potato leaf hopper resistant cultivars were developed in the 1980 and were released in the 1990s by USDA/Kansas State University and Purdue University. In conclusion, early alfalfa introductions into the US involved germplasm that was/is in the NPGS collections. Most cultivars description do not indicate specific PIs used. The role on NPGS in supplying germplasm, including old cultivars, that ultimately leads to a new cultivar is unfortunately murky. Some clear examples exist of the value of the collection. A question about the system tracking of materials going back to the origin from they were collected or originated from.

8:30 am: Kevin Jensen: Impact of NPGS on Grass Cultivar Development

Grass is in every history of the country. The first collections came in from N.E. Hansen and there were 3-5 of them that went to Florida to be evaluated and they were included in the NPGS. In early 1900s with the Carey Act, Newlands Act, and others allowed the people to move into the Midwest and the West to utilize the lands there. About 100 million acres. Dust Bowl caused big losses in the 75% of topsoil loss. “Fairway” wheatgrass was released by N.E. Hansen and others, selected from original PI 19536. The entire west was seeded with the wheatgrass, which saved the west from drought and bringing it back to normalcy. In 1969 ‘Parkway’ cultivar was developed and the plant breeders started looking for traits. Then ‘Ruff’ was developed in 1974 with 3-cycles of selection. ‘Hycrest’ was developed in 1984 in response to other issues facing agriculture production in the west, including obnoxious weeds. Overtime, new varieties were developed using other plant introduction (PI) parents. Recent impact includes ~8,000 lbs stock seeds sold for ~$5,888,970 worth. A collection of varieties/accessions that was used in Kazakhstan for trials there in a region receives less than 5 inches of annual rainfall. Recent Impact of this work 11,313 lbs ‘Vavilov II’ and 1,463 lbs ‘Stabilizer’ stock seeds sold for ~$8,011,624. If you look at grasses, that was how many pounds it cost. I showed you what our grasses did as we went through, and more of a masses or natives, so they're not necessarily an PI system. The presentation focused on how the improvement and development of wheatgrass and Russian wildrye was linked to the NPGS. Also, how the meadow brome cultivar development is linked to the NPGS and its impact/importance in the Western Region grazing pastures. A discussion ensured regarding having a value for beef produced from these pastures, wildfires prevented and other benefits from having these breeding lines developed for the area.

Business Meeting:

8:55 am: WRPIS: Marilyn Warburton

The presentation started with basic introduction of the experiment stations of 13 land-grant universities in the Western region supply the funding from their Hatch (Federal) funding and the committee members as representatives of the land-grant universities + an advisory (Scott Hulbert) and WRPIS station coordinator (Marilyn Warburton). The presentation talked about the genetic resources management, mission related to PGR research/support and the budget breakdown (federal, W6 in-kind, and extramural funds). The presentation gave an overview of the major genetic resource programs (e.g., Agronomy, Phaseolus, Cool-season Food Legumes, Horticultural Crops, and Temperate-adapted Forage Legumes). The presentation highlighted the pathway program working with graduate students and their path for a permanent position after their graduation. The number of accessions for the 5 major curatorial programs and the assigned major crops at the WRPIS as June 2023 is presented in Figure (10). Staff availability has affected the ability to keep up with the large number of accessions and to keep them available for orders all the time.

*SOS seeds are not actively curated.

Figure (10): The five curatorial programs and assigned major groups at WRPIS as June 2023. (See graph in Attachments)

The total holdings currently stand at about 102,000 accessions in the genebanks, and they are increasing over the years. Over the last 12 years, 424,555 accessions were distributed out of 14,515 orders. A question to Peter Bretting was raised regarding the support needed from the W6 committee to ensure an increased financial support from the legislators in Washington, DC to the genebanks to continue the critical work they are doing, ensure expansion to include all accessions availability, and clear the backlog due to low staffing availability. Peter explained the effort in 2019 and 2020 (Farm Bill mandated NPGS Plan) and how the National Genetic Resources Advisory Committee (NGRAC) had reviewed the plan and provided significant input, which is appointed by the Secretary of Agriculture to advise him on it. Peter explained the process that the request has been going through so far. When the final review will happen was not clear yet, but there was hope for it to be made public soon. Peter also explained that they are following up on the process almost every-other-week to ensure its still in the pipeline.

Additional discussion was about the Stakeholder Liaison group started from stakeholders from each state in the region to act as advocates. A question regarding the liaison groups best time to reach out to congress and advocate on behalf of the committee. The answer was that the committee's job is to provide them with information only. Peter provided additional information about the best ways to approach the issues. A question was raised regarding what’s needed from the W6 committee annual meeting and what needs to be accomplished. Additionally hearing from the curators regarding their needs and how the committee can help. A decision was made to start the discussion via an email and plan for future Zoom meeting in about 6 months from now.

9:15 am: The topic of making the W6 project more sustainable and impactful was initiated. At this point, the discussion deviated from the agenda. The RTAC did not get to the discussion of the W6 Stakeholder Liaison group, the efforts of the WRPIS, the NLGRP in Fort Collins, and the National Program Leader for the NPGS to demonstrate impact of the genebank, and/or how the western genebanks could work better with the Agriculture Experiment Station Directors and others in the states of the Western Region. Instead, the question was asked about the efforts to create and present to Congress a Plan on what would be needed to fully fund and staff all the USDA ARS genebanks to avoid any backlogs in our core mission activities of collection, curation, regeneration, evaluation, characterization, and distribution of plant genetic resources of economic importance to the US. The “NATIONAL STRATEGIC GERMPLASM AND CULTIVAR COLLECTION ASSESSMENT AND UTILIZATION PLAN” was requested by Congress in the 2018 Farm Bill, and it was an effort led by Peter Bretting, National Program Leader for the NPGS, and colleagues from the NPGS. It has been approved by various scientific and stakeholder groups, and the necessary offices within the USDA and the federal government. Peter reports it has been given to the Secretary of Agriculture, who will be the one to present it to Congress. This will hopefully happen soon, and the full copy of this Plan (and its abbreviated version), once public, can be provided to the RTAC. If this Plan is fully resourced, the genebanks will be able to modernize, remove current risks to the collections and the curation activities; increase activities on phenotypic evaluation and genetic characterization; and initiate pre-breeding activities when needed. All this will be done in conjunction with US public and private institutions with an interest in seeing the genebanks and all associated data become more freely available. If funding from the Plan is not available, or not to the level requested, we can begin discussing our alternative strategies for increasing funding and resources at our December meeting, or next summer.

9:53 am: Elections of Vice Chair and Secretary

Kevin Jensen - agreed to continue serving as the W6 RTAC Chair

Amjad Ahmad - was nominated and elected to serve W6 RTAC Chair-Elect

Donna Harris - was nominated and elected to serve W6 RTAC Secretary

10:10 am: 2024 W6 Committee Meeting Location

A discussion regarding the location for 2024 committee meeting was initiated. Honolulu, HI, Prosser, WA and Logan, Utah were suggested as locations for the next meeting. Availability of stable internet connection to ensure the ability to have hybrid in-person and online meetings possible was important. Some discussion on reformatting the meeting was also initiated, but it was realized that we didn’t have time to complete the discussion and make decisions. Thus, it was decided at this point that we would hold another meeting towards the end of the year (probably in December 2023) to decide the location, format, and attendees of the 2024 meeting.

10:45 am: Adjourn business meeting.

“Field Tours” – for those on site

Dr. Per McCord, WSU IAREC Horticulture Department Stone Fruit Breeder and RTAC WA State Representative, provided the group a tour and overview of the cherry breeding program, the modern and recently installed computerized (AI) automatic fruit sorter, and fruit tasting, which was delicious.

During the lunch break a short presentation was provided by Research Geneticist (breeder), Kayla Altendorf of the USDA ARS Forage Seed and Cereal Research Unit worksite in Prosser. Presentation involved describing an introduction to the crop, importance of the local/regional growing area, about the plant and pollination biology, the breeding process and cycles and what traits the program is working with specifically. After lunch, the group visiting the Golden Gate hop farm facilities, part of the larger Hopsteiner Inc. farms. We met hop breeder Ryan Gregory, who provided some background on the history of the family-owned farm, some of the breeding objectives and a detailed tour of the hop processing facilities.

Accomplishments

<ul> <li>Short-term Outcomes: <ul> <li>We acquired 877 new accessions including 796 native plant accessions collected by the Seeds of Success (SOS) project, 67 expired IPR/CSR accessions from NCGRP, 11 Phaseolus polystachios accessions, 195 Medicago truncatula accessions received from INRA, France, and 3 other miscellaneous accessions.</li> <li>We distributed a total of 34,861 packets of seed samples to 525 requestors with addresses in each of the 47 domestic states and territories and 38 foreign countries. 55% (19,319 packets) were distributed to the U.S. and 46% (15,542 packets) were distributed internationally. A total of 8,767 packets from WRPIS went to the 13 U.S. Western states.</li> <li>We uploaded 169 observation data points on 136 accessions into the Germplasm Resources Information Network (GRIN)-Global database. These data points are on 5 established descriptors for 2 different crop species. Our collaborators contributed 88% and WRPIS staff provided 12% of the evaluation data. The database is accessible by researchers worldwide via the internet. A total of 551 images were loaded on 422 accessions, 494 of them were seed images.</li> <li>We entered 3,763 seed viability records into GRIN-Global during the reporting period. The USDA ARS National Laboratory for Genetic Resource Preservation (NLGRP) in Fort Collins, CO tested 2,516 accessions and 1,245 accessions were tested by the Pullman staff.</li> <li>We shipped 1,632 seed inventories to the NLGRP (1,303 accessions were from the SOS collection) and no inventories were sent to the Svalbard Global Seed Vault, Svalbard, Norway for secured backup this year.</li> </ul> </li> <li>Outputs: <ul> <li>A total of 14 peer-reviewed journal articles and a PhD dissertation were published in 2022.</li> <li>The Cool Season Food Legume (CSFL) program published a collaborative high-throughput spectral reflectance method to select drought tolerant lentil accessions using a multispectral radiometer. Eleven lentil plants with high promise as donors of drought tolerance traits were identified from a total of 49 evaluated in a multi-year trial.</li> <li>The CSFL program and collaborators identified two new quantitative trait loci (QTL) providing resistance to Fusarium avenaceum in lentil, and two PIs (PI299116 and W627760) that were highly resistant. They also identified markers linked to host resistance in lentil to the pea aphid, and two highly resistant lentil accessions, PI 329157 LSP and PI 432085 LSP.</li> <li>The Agronomy program generated re-sequencing data for 864 safflower accessions from which single nucleotide polymorphisms (SNP) will be extracted to study population structure, relatedness, duplications, and uniqueness, and to create a panel of lines that can be studied via genome-wide association studies (GWAS).</li> <li>The Phaseolus program started a new lima bean project that supports regenerations, phenotyping, and genotyping of 700 lunatus in the collection. They also collected 11 new P. polystachios accessions from Florida and Georgia.</li> <li>The alfalfa genetics research program mapped genetic loci associated with verticillium wilt (VW) resistance in alfalfa populations and identified two candidate genes for disease resistance. The gene markers and protocols have been shared with alfalfa seed companies for marker assisted selection. The alfalfa genetics program also created a mapping resource for salt and drought stress and identified 84 SNP markers and putative candidate genes associated with stress resistance, and eight drought resistant lines, which have been shared with seed companies.</li> </ul> </li> <li>Activities: <ul> <li>The Horticulture crops program studied 150 accessions of 28 species of Lactuca germplasm from around the world via evaluation and genotyping, for a more accurate characterization of the collection. Several accessions were found to be misidentified and were corrected, resulting in adding 2 new species to the collection and expanding our diversity.</li> <li>The Pathology program worked to develop plant tissue culture procedures using the basal stem disk as the explant for in vitro propagation of virus free garlic. The program also worked on optimizing culturing conditions for high yield zoospore production in Aphanomyces euteiches strains to be used in future large scale lentil inoculation studies.</li> <li>Research into GWAS to identify markers, genes, and pathways associated with traits of interest is underway to create new methodologies to expand pathway analysis into self-pollinated crops for the first time, and markers linked to seed protein levels in peas have been identified.</li> </ul> </li> <li>Milestones: <ul> <li>Since this project is ongoing indefinitely, we meet our biggest milestone annually by maintaining the accessions and the data in the USDA ARS Western Regional Plant Introductions Station (WRPIS), also known as the Plant Germplasm Introduction and Testing Research Unit (PGITRU) in a manner that allows the germplasm, and its associated information, to be freely accessible.</li> <li>One specific milestone for 2022 was the creation and approval of a new 5-year USDA ARS Project Plan for the PGITRU in National Program 301. An overview can be found at: <a href="https://www.ars.usda.gov/research/project/?accnNo=443951">https://www.ars.usda.gov/research/project/?accnNo=443951</a>.</li> </ul> </li> </ul>
