Brief Summary of Minutes
Opening and Introduction:
- Call to order, 8:50 AM
- Mike peel (ARS Utah) opened the meeting by welcoming the group. Attendees introduced themselves.
- This is the first official meeting as the NE1710 officially started on October 1,
- Comments from NIFA:
Ann Marie Thro (NIFA) led the comments with emphasis on the role of the program leader at NIFA.
- “The bottom line to help you all get money and help us get money to you”.
- Cards of program specialists were circulated.
- The Big task of the specialists is to answer questions: Give us a call and will answer them or help find the answer.
- There is a new acting director in NIFA on loan from ARS, Thomas Shanower. He is entomologist by training. He worked 20-30 years in the Pacific west area as associate director and in international agriculture.
- Those interested in the funding that USDA offers: one is a list of competitive grants, she circulated, including for alfalfa research. Budget for these grants, National program leader names and contacts are listed--you can call them with questions.
- Two sources of funding of interest to this group: Hatch projects and multistate projects. For each experiment station, 25% of the Hatch funds are for multistate projects. In the past 3 years, Hatch funds have been flat. The alfalfa research funding increased last year and decreased this year. A document shows Explanatory notes of funding proposed for next year’s budget (document circulated). Ann will send information on where to find them.
- Topics to help NIFA get funding include listening sessions. You can find a verbatim transcript online and input from last year under NIFA listening sessions. Most of the comments last year came from Nutrition. It would be worth to think about input and contribute individually or as group to direct the agency in directing discretionary funding and to answer to congress.
- The annual reports you write, especially the impact and outcome statements, let us know what was achieved. If not sure how to report it, call us. They help justify what you do.
- Viands (Cornell) commented that a couple of people from NIFA called to offer a workshop on writing impact statements to NE1710, but they later declined for a different schedule. They were going to come to this group’s meeting this morning.
- Papadopoulos (AAFC) commented that in the past, each of us submitted an annual report that included impact statements, and it gives indication on to what other people are doing.
- Viands: This is part of the end report.
- Ann: sent around a list of state liaisons from NIFA.
- Missaoui (UGA) asked what is the role of the state liaison?
- Ann Marie: The Deans and station directors submit a report accountability from Hatch funds, and the state liaisons are the ones who review them. You can call them and find out more about them.
- The Impact statements are the most read part. They are non-technical summaries written so that a congressional rep can read them. They help your area of research attract more funding.
- Papadopoulos and Ann Marie discussed NIFA funding to Canadian researchers.
- Ann Marie confirmed that funding can go international if the lead is from the US and they can benefit the US. These are mostly AFRI and competitive grants. Hatch funding cannot go international PIs because they are tied to the state.
- NE1010 attracted most funding other than Hatch. You can view funding on a website at USDA.gov/Data gateway to find out how much NE1010 got in funding. Every proposal funding is there.
- Viands commented that this might be important when we write the proposal for the next 5-year period!
- Viands (Cornell) asked if everyone was an official member of NE1710.
- Papadopoulos (AAFC) replied that Canadians have been a part of the group. Their department encourages participation. Not sure if they are official and want to find out the process for Canadian to have official status.
- Don will find and send information.
Open discussion on NE1710 projects by objectives and forage species
Mike Peel commented that these are brand new projects. Some people have reports especially those from NE1010.
- Developing broadly adapted, climate resilient forages for sustainable cropping systems.
Sub-objective 1.1. Developing regionally adapted, resilient alfalfa germplasm pools.
- Papadopoulos (AAFC): Circulated his project report, and explained the part of the projects that belong to 1710. The first project is with H. Riday (USDA-DFRC, Wisconsin).
- Riday (USDA-DFRC, Wisconsin) commented that currently there are no sub-projects and overviewed 1.1.
- Four northern alfalfa pools are being evaluated (Central Asian, Northern Afghanistan, Turkish, Siberian, Balkan, North Europeans pool,)
- Have received data from New York, Quebec, Wisconsin, Lethbridge, and Davis.
- Will make selections from the evaluation and release material as PIs.
- Started collecting data. This started as AFRP project to do pre-breeding on accessions.
- There are other germplasm developing projects that can be added as sub-objectives.
- Brummer (UC Davis): Discussed an AFRP project aimed at maximizing recombination in Northern and Southern germplasms. Broadly speaking, lined 4 pools in California and can add southeast.
- Page 11 of the proposal: germplasm pool development describes the tasks and the proposed pools.
- Viands (Cornell) asked about the number of people cooperating on these projects.
- Riday (USDA-DFRC, Wisconsin) replied that this is why it needs to have sub-objectives.
- Brummer (UC Davis) showed a presentation on the layout of the project based on Simmons 1993. Base broadening of germplasm over time. Take germplasm collection, pre-breed. This is something the community should do and add germplasm to breeding material. Large-scale number, wide range of entries, crude selection. Make 5% selection and feed it back to the pool. The general idea are geographic origin may have difference in genetics.
- Brian Irish asked whether the basis of defining the pools is strictly based on passport data.
- Riday (USDA-DFRC, Wisconsin) replied that he consulted Russian databases and based on the name. You can track where in the former USSR they originated from (exact region). You can do the same for Chinese material.
- Northern pool: H. Riday (USDA-DFRC, Wisconsin) completed the first cycle of selection; general characterization was mostly visual, and he move quickly to selection. Percent selection 5-8% that feeds back to the pools (maintaining the same pools) unless molecular data shows otherwise; in that case we need to reconsider the pools. Checks are used such as ‘Vernal’ for comparison.
- Viands (Cornell) commented: pleased this is happening because this was suggested 25-30 years ago and never took off the ground because breeders in companies were not willing to have it done.
- Riday (USDA-DFRC, Wisconsin): All the data collected are visual, and it will be fed back into the pools rather than expanding the collection. These pools are different from the 200 PIs Stephanie Greene identified as core collection.
- Viands (Cornell) asked whether anybody used that core collection for breeding purposes. It is unknown.
- Papadopoulos (AAFC) suggested having standard data collection methods to describe the same phenotypes and have common data.
- Riday (USDA-DFRC, Wisconsin) sent an instruction sheet to Lethbridge.
- Monteros (Noble Res Institute) suggested using pictures of 1 to 5 scores.
- Checks like ‘Vernal” are usually included. There is also interest in persistence across regions.
- Missaoui (Univ. Georgia Missaoui, H. Riday (USDA-DFRC, Wisconsin), C. Brummer (UC Davis), Brian Baldwin (Mississippi State Univ.) discussed the type of traits, especially the correlation between true yield and visual vigor and the validity of visual scores as surrogate to yield.
- Ali Missaoui described the evaluation of an alfalfa collection of 1580 entries at UGA and the type of data collected. The data will be deposited back with NPGS.
- Monteros (Noble Foundation) asked about sequencing, whether on single plants or more.
- There is more variation within PIs than between. H. Riday (USDA-DFRC, Wisconsin) indicated that 80% allele variation within a PI is considered uniform in forage populations. Allele frequency in alfalfa commercial seed field with the non-dormant cultivars are clearly distinct and less diverse.
- Papadopoulos (AAFC), D. Viands (Cornell), H. Riday (USDA-DFRC, Wisconsin): discussed alfalfa selection in coastal regions. Selection of surviving plants after winter.
- For those interested in PI evaluation in Northern locations, you can contact H. Riday (USDA-DFRC, Wisconsin) for new germplasm evaluation.
- We can add more sites for in the Northern area if there is interest. Clarifications were made on the type of data to collect from Canada.
- Southern pool: Charlie will lead.
- Mississippi is interested in adding a location and will coordinate with GA on the list of entries to test.
1.2. Developing switchgrass germplasm with improved fungal pathogen resistance
- Viands started the discussion:
- Shawn Kenaley is leaving Cornell. Gary Bergstrom wants to take over leading the survey of switchgrass diseases. He plans on replacing Shawn with another postdoc.
- Opened discussion on what needs to be done.
- Missaoui will talk to Shavannor Smith if she is interested in joining the project.
- The activities are just a survey and no need to plant.
- Youssef is not involved in the objective but interested in getting information. He has breeding trials where data can be collected from and he is interested in being added to the objective.
Break
1.3. Developing resilient cool-season grasses adapted to variable climatic conditions.
- This topic was discussed a couple of years ago. The study is now in the ground looking at orchardgrass, tall fescue, and bromegrass vigor. Also looking at quality.
- There is a selection component. There are several locations.
- This is a new project and not a direct continuation.
- Biligetu (Univ. Saskatchewan) commented that Bruce Coulman is semi-retired, but he is writing a paper on the project from previous project data.
1.4. Determining the extent of genetic variability of condensed tannins among currently available birdsfoot trefoil cultivars and elite lines.
- Papadopoulos (AAFC) began the discussion.
- The project was supposed to be initiated this year but Rebecca Brown (Rhode Island) could not start the project this year because of funding. She will start next year. The handout provided includes evaluation of germplasm for cooperators. The goal is to evaluate germplasm from other collaborators. An animal scientist will be looking for the effect on parasites.
- Riday (USDA-DFRC, Wisconsin) asked if the evaluation started yet. He has material with high and low tannins from Nancy. He needs to send the seed to Y. Papadopoulos (AAFC).
- The real step is to look at chemistry and tannins on animal parasites. Kathleen was added to the project and she will be looking at the chemistry: type of tannins and in vitro techniques. The samples will be freeze dried and sentr for processing and analysis of composition.
- Papadopoulos (AAFC) and Rebecca have preliminary data, looking at leaf powder effect on worms in sheep. As well as in vitro, looking at effect on eggs and emergence of parasites.
- Right now there is Nova Scotia, Utah, NY, and Wisconsin participating. If others are interested they can be added.
- Riday (USDA-DFRC, Wisconsin) commented that in Wisconsin, there is someone using 3D-NMR looking at types of tannins in plants.
- Kathleen is interested in knowing what fraction.
- The person’s name is Wayne Zeller and can be added as collaborator if he interested.
- Nancy would like to be added to the project but no site. She has high and low tannin genotypes.
- Plots will have 10 plants and replicated. There is enough seed of the experimental population to be sent to participants.
- Riday (USDA-DFRC, Wisconsin) is interested in tannin stability in hay.
- Discussion on tannin fractions and chemistry with Kathleen. John is convinced his chemistry is the best.
- Don asked what does it take to send the ground material to Canada for tannin analysis.
- Annie replied: Phyto certificate. H. Riday (USDA-DFRC, Wisconsin) suggested that it may not be needed because most of the germplasm that goes to Canada such as red clover has no restriction. Y. Papadopoulos (AAFC) will find out.
- May combine samples from many replications.
- Nancy Ehlke commented that tannin content is affected by environment but ranking is consistent ….No GXE.
- Papadopoulos (AAFC): Year and location effect will be assessed. By 2020 will have an idea about GXE. He previously did greenhouse and field tests and found different rankings.
- Papadopoulos (AAFC) will send details on harvest and sampling for analysis. Check cultivars will be determined.
Objective 2. Understanding genotype by environment interactions across multiple forage species.
- Discussion on species (fescue, dactylis, bromus…), Quality and cell wall characteristics, and selection components.
- Uniform cultivar trials with the same entries across locations to be able to test GXE.
- Suggested to include Tim Phillips (Kentucky) as a participant.
- How many cultivars to include? Discussion on whether to go with cutting or grazing or both. Suggested to stay with cutting.
Tall fescue:
- Missaoui (UGA) will take the lead on coordinating the fescue trials. Participants will be Utah (Joe), Nova Scotia (Kathleen), Cornell (Don), GA (Ali), Davis (Charlie), and possibly Kentucky (Tim to ask).
- The target is 30 entries.
- Quality analysis can be done in GA, Mississippi volunteered for the analysis. Y. Papadopoulos (AAFC) suggested to target first growth for quality analysis.
Orchard grass:
- Joe (Utah) will lead.
- Saskatchewan, Cornell, UGA. Kentucky will participate with plantings starting this fall (first august).
- The lead will collect the seed and distribute it to the sites.
- Plot size 15 x 5 ft or 2 x 1 m. at least 2 checks for each region.
- Papadopoulos (AAFC) can contribute germplasm but cannot do a trial. He can send one entry.
- Each lead needs to send an email reminder to the collaborators to supply the seed for the trials.
Trefoil: Y. Papadopoulos (AAFC) is the lead on trefoil cultivar trial.
- Same plots as tannin plus additional standard entries. Yield will be needed. First sample for tannin and then harvest the plots. 2019 will be the start.
Red clover: H. Riday (USDA-DFRC, Wisconsin) will lead:
- Already have trials ongoing in Wisconsin, Cornell, Quebec, and Nova Scotia. In fall 2019, GA can have a trial. Nova Scotia has two cultivars that need to be tested. Standard checks (Marathon, Freedom, Cinnamon plus, Canadian checks)
- There are not many commercial companies doing red clover breeding.
Alfalfa: Will discuss yield trials in next year’s meeting. In Utah, they do one trial every 3 years.
- Cornell has a testing program on fee basis for companies but free for universities.
Cicer milkvetch and Sainfoin: Surya Acharya is doing work on these species. He was not present in the meeting
Anne Marie raised a question about GxE for objective 2.
- Viands (Cornell) replied that for perennial species in order to be of interest to companies it has to be broadly adapted unlike annual species where you can have target regions. It has always been a justification when writing the multistate projects since forage breeders are getting fewer and fewer.
Discussion about the need or not for PVP. It is not as necessary as it used to be.
Next meeting location:
Next year’s meeting will be in Athens, GA, on Wednesday May 29, 2019. A. Missaoui (Univ. Georgia will be the chair for next year, Bill Biligetu – Univ. Saskatchewan (CAN) will be the secretary.
New Items:
- Brummer (UC Davis): Interested in population improvement for diploid alfalfa. (falcata, caerulia, etc.). There are some accessions that are very productive based on previous evaluations. Compared to tetraploids, these have smaller leaves and originated from East Turkey (Caspian Sea). Potential interest from Quebec, Davis, Cornell, H. Riday (USDA-DFRC, Wisconsin), Arvid Boe, Mike Peel. Seed will come from GRIN. Charlie will start a location this coming fall in Davis.
Meeting ended 11:45. Lunch in Student Center at USU campus.

Brief Summary of Minutes
Opening and Introduction:
- Call to order the meeting at 8:20 a.m.
- Ali (Univ. of Georgia) opened the meeting by welcoming the group, and introduced the agenda for the meeting.
- Ali introduced Sara Delheimer- Impact writer/Impact writing workshop presenter for multistate research projects.
- Sarah provided a 20-min presentation followed by actual practice for writing effective ‘Impact Statement’ for research reports. Brief summary of the presentation:
- Communicating relies on members of the project group, and a good report is a first step to sharing your work with other researchers, general public, government/funding agencies.
- Audience is most likely non-experts, and may not know the technical statement, and the impact statement is a brief of summary of work and why it matters.
- There are many different forms: a good impact statement is brief (So what? Who cares? – Changes ahead- social, environment, behavior, knowledge).
- The Issues- actions (small pieces), output/results (moral, take home message, but this is not impact)-- Impact story (how paper advances the sciences, workshop impact on farmers, then how they changed the social, economic, environmental problems, or behavior changes). In cases of public value statement <= impact statement, outcome<= impact statement. It is good practice to indicate public value in the impact statement.
- Sarah mentioned that additional information for writing impact statements can be found at https://www.mrfimpacts.org/about-impact-statements
- Faith Peppers from the Univ. of Georgia provided a basket of “Taste of Georgia” to the meeting group, and she also provided resources for developing impact statements for Multistate projects.
Break at 11:15AM
11:30AM Discussion on NE1710 project
- Developing broadly adapted, climate resilient forages for sustainable cropping systems.
Sub-objectives
1.1. Developing regionally adapted, resilient alfalfa germplasm pools.
- Riday (USDA-DFRC, Wisconsin): Four northern alfalfa pools were developed prior to the NE1710 project. For NE1710, the four populations were transplanted at Wisconsin, Cornell, Davis, Quebec (Canada), and Lethbridge (Canada). In fall 2018, plant selection was made at the Cornell site, and all other sites plan to make selections this year. Data will be collected at all sites. NIFA-AFRP provided additional funds, which enabled Cornell, Wisconsin, and Davis to establish three additional sites this year. A new NIFA grant proposal was submitted for the next round. The goal for this winter is to harvest seeds for seed increase. The plan is to release four germplasm pools.
- Southern region: The Noble Research Institute is reviewing their programs, and alfalfa may be considered whether to continue for research.
- Biligetu (U of Sask.) mentioned that he can establish an alfalfa variety trial if an additional northern site is needed.
- Missaoui (Univ. of GA) asked about the number of cycles for the germplasm pool, and H. Riday mentioned they completed one cycle of selection.
- Viands (Cornell) asked if he would combine the seeds from all sites to release four populations/germplasms. H. Riday suggested having a group discussion, and the idea was not to increase number of populations, thus maintaining the four pools. Heathcliff has data for all pools.
- Viands (Cornell) suggested that a convergent-divergent selection may be useful for the second round of selection. So far has five sites with potential seed harvest. It may be good to have separate material by each location.
- Riday mentioned a hairy a vetch project. In that project, they selected a few generations at each site before material exchange among sites. Seed production at one site may be a challenge for all sub-populations. The fund has a one-year extension until next year.
- For southern pool- Missaoui (Univ. of GA) evaluated a large number of germplasms (380 PIs) in the last couple years. Data were collected, and selection was made from 27 PIs (3 plants/PI). The target fall dormancy was 6-10.
- Missaoui (Univ. of GA) also is currently evaluating PIs under low soil pH, and plans to do a GWAS study.
- Missaoui (Univ. of GA) has a few experimental alfalfa populations and is currently increasing seed at Idaho. He will do a variety trial next year, and other alfalfa germplasm with FD 6-10 can be entered into this trial.
- Riday mentioned that Debby Samac (USDA-ARS) and others are doing a sequencing project (alfalfa, blueberry, sweet potato), which includes sequencing alfalfa (ARS project).
1.2. Developing switchgrass germplasm with improved fungal pathogen resistance
- Viands: Gary Bergstrom’s post-doc, Shawn Kenaley led this objective, but he is no longer with Cornell. Gary is still the lead; he is interested in rust and smut race identification, and if there are samples with these diseases, they can be sent to him.
- Don expressed concern that we are already in Year 2 of 5 years of the project, and we need to make more progress.
- Boe (South Dakota State Univ.) mentioned switchgrass is currently tested at 13 different locations for a new study on GWAS of switchgrass, and he is phenotyping the materials.
- Missaoui will talk to Shavannor Smith to determine if she is interested in joining the NE1710.
- Baldwin (Mississippi, USA) also sent switchgrass disease (Smut) samples to S. Smith.
1.3. Developing resilient cool-season grasses adapted to variable climatic conditions.
- Biligetu (U of Sask.) updated the project progress. This project included orchardgrass, tall fescue, meadow bromegrass, and timothy. The best two lines + check variety from each of three locations (Saskatoon, Quebec, Logan) were used for each species. Six sites were selected for this study based on their latitude including two sites each at Quebec, Canada; Saskatoon, Canada; and Logan, UT. All plots (pseudo-plot of 48 plants/plot) were transplanted and established in 2018. First year data will be collected in summer 2019.
1.4. Determining the extent of genetic variability of condensed tannins among currently available birdsfoot trefoil cultivars and elite lines.
- Papadopoulos – (AAFC, Nova Scotia) updated the project. Y. Papadopoulos selected eight trefoil breeding lines for condensed tannins, and has sent seed to other locations. Y. Papadopoulos commented that it is currently too wet to seed at his site. Rebecca Brown (U. Rhode Island) will seed in August 2019, and Wisconsin is planning to seed in the fall 2019 as well. Cornell will seed the trial within next few weeks.
- Riday has developed two entries of high and low tannin germplasm, and asked if he can add them to the list. Y. Papadopoulos suggested to use the same experimental design.
Objective 2. Understanding genotype by environment interactions across multiple forage species.
- Tall Fescue: A. Missaoui commented that 14 tall fescue entries received (4 from Tim Philips, 3 checks, 7 from Ali’s program), and sent seeds to Cornell and Nova Scotia. Y. Papadopoulos will plant in spring 2019.
- Orchardgrass: B. Baldwin commented that he has one orchardgrass population to test, and A. Missaoui mentioned he has seven entries with adequate seeds for three to four locations if others are interested in a trial.
- Red Clover: H. Riday plans to collect red clover data to examine the relationship between nursery and sward density trials, if he can get the data for red clover from other sites. D. Viands mentioned Julie Hansen may have some data. D. Viands commented that the 2017 red clover trial with materials from U of Georgia, and Wisconsin, shows variance for persistence. Julie can select plants for them if there is an interest. Ali and Heathcliffe expressed interest. Ali mentioned that their extension staff has variety trials for various species, and if anyone wants to test their material, they can talk to them.
Viands suggested having a new administrative advisor for NE1710 project because he plans to retire at the end of 2020. The administrative advisor has to be a university faculty, and D. Viands will talk to potential candidate faculties. Note: After the meeting, Viands found out that the administrative advisor needs to be from the Northeast since this is an NE multistate project. He will ask his replacement at Cornell to become the administrative advisor, starting 2021.
Next meeting location: Lansing, Michigan (Joint meeting with the North American Alfalfa Improvement Conference, June 1, 2020).
Chair: Bill Biligetu
Secretary: Brian Baldwin
Meeting adjourned at 12:40 p.m.
Appendix 1
Northeast 1710 Annual Report, May 2019
Brian Baldwin and Jesse Morrison
Mississippi State University
Efforts to improve warm- and cool-season native grasses for forage, habitat and reclamation have moved forward. Selection for rapid germination of five warm-season native grasses (lowland and upland switchgrass, Panicum virgatum; big bluestem, Andropogon gerardii; indiangrass, Sorghastrum nutans and little bluestem, Schizachyrium scoparium) have been successful; three other species are still undergoing selection (Eastern gammagrass, Tripsacum dactyloides; purpletop, Tridens flavus and beaked panicum, Panicum anceps). Examiners have approved the lowland switchgrass variety ‘Expresso’ (syn ‘Espresso’), and issuance of the PVP (#201800200) is pending. The upland short-statured switchgrass variety ‘Robusto’ has been submitted for PVP examination; the other three will follow in June. Breeder’s seed of the five entries has been delivered to Roundstone Native Seed, LLC. (Upton, KY and Live Oak, FL). Foundation fields have been established. Spring, 2020 will initiate the generation of Registered seed increase.
‘Tusca’ is a cultivar of lowland switchgrass selected from ‘Alamo’ (USDA NRCS, Knox City, TX) for resistance to the herbicide imazapic. Plant patent has been applied for and published (https://patents.google.com/patent/US20190014734A1/en ). Additional screening to determine if selection for Tusca conferred cross-resistance to similar ALS-inhibiting herbicides was conducted. Five ALS-inhibiting herbicides including; imazapic (IPIC), imazamox (IMOX), imazapyr (IPYR), imazethapyr (ITHR), and metsulfuron methyl (MSUL), were tested on Alamo, Tusca, and wild-type johnsongrass [Sorghum halepense (L) Pers.] at five rates (25, 50, 75, 100, and 125% of the label rate) plus an untreated control, under laboratory and greenhouse conditions. Johnsongrass was used as a reference species to confirm efficacy of herbicide treatments. Six replications of 25 seeds of both cultivars and johnsongrass were screened for response to herbicide treatment at germination as well as the 3-leaf stage. Mean germination percentage for untreated Tusca, Alamo, and johnsongrass were 71.5, 24.8, and 40.8, respectively. Compared to controls, mean germination percentage of Tusca remained >50% at all rates of ITHR and IMOX, whereas ITHR decreased germination of Alamo to <25% and IMOX to <50%. While Tusca shows some improved tolerance to IPIC at germination, greater tolerance was found to ITHR, IPYR, and IMOX, whereas mean germination percentage of Alamo was significantly reduced by all treatments.
Work with North American native grasses has almost exclusively focused on warm-season, C4 grasses. There is still a great need for the inclusion of native cool-season grasses for reclamation of grasslands. Originally lumped in with Canada and Virginia wildrye (Elymus canadensis and E. virginicus, respectively), southeastern wildrye (E. glabriflorus) was recognized as a separate species in 2007. The occurrence of southeastern wildrye in the Deep South is favored over Canada wildrye, and in full sun locations, southeastern wildrye predominates over Virginia wildrye. Being relatively new to agronomists, cultural parameters and establishment experiments were conducted to aid in research and breeding programs. Optimal germination requirements were examined. Data suggests optimal temperature for germination is between 15-20°C. Photoperiod did not affect germination. Germination is greatest at pH greater than 5.0, though germination does occur at lower pH. Seed conditioning (removal of the beard) decreases germination, but also negatively impacts shelf life of the unplanted seed. Maximum seedling emergence occurs at a planting depth of 0.64 cm. While most references indicate that native grasses do not need high levels of fertility, southeastern wildrye is highly responsive to nitrogen application. Like most native grass species, persistence declines with greater than two cuts per season.
There are no herbicides currently labeled for use in southeastern wildrye. Tolerance of southeastern wildrye to application of popular herbicide chemistries at the five-leaf stage have been explored. Herbicides included imazethapyr, sulfometuron methyl, quinclorac, mesotrione, sulfentrazone, imazapic, nicosulfuron, thifensulfuron methyl, and sulfosulfuron. Herbicides were applied at label rates with recommended adjuvants. Plant height, seed and biomass yield, and plant population were negatively impacted by application of sulfometuron methyl (Oust XP) only. Anecdotal evidence indicates limited tolerance to the auxin-type herbicides. Southeastern wildrye is primarily self-pollinated, though about 8-12% crossing does occur and extends to related species. Selection and genetic improvement requires the accumulation of large numbers genotypes and the close quantification of specific characteristics.
Exotic cool-season grass screening for heat tolerance in orchardgrass (Dactylis glomerata) and annual ryegrass (Lolium multiflorum) has been conducted for three years (Eric Billman Ph.D. dissertation). Recurrent phenotypic selection was used to select elite individuals of annual ryegrass and orchardgrass that expressed improved germination and growth at high temperature. Selections were conducted within growth chambers at fixed temperature and light regime (40/30°C, 12/12 hrs light/darkness) to eliminate effects from environmental variance. Following three cycles of selection, we observed gain in selection of the base population for both species. Annual ryegrass mean cumulative germination at 40°C for cycle 3 peaked at 45.8% and orchardgrass mean cumulative germination at 40°C for cycle 3 as 82.7%. Observations 20 days after the near record low temperatures in January 2017 indicate selection for heat-tolerance did not affect cold tolerance. Persistence observations are currently underway for improved orchardgrass.

- GXE interaction in perennial forage species The sales volumes and profit margins on forage seed sales are slim. Therefore perennial forage cultivars need to be broadly adapted in order to gain acceptance by the seed industry. The multistate group of researchers are collaborating to identify the extent of the variations in performance of these species in different environments across the US and Canada. We have several varieties developed in different parts of North America that are being evaluated in multiple locations for several years to test their forage yield and quality across environments. The results will guide future breeding programs on which representative environments they should test experimental populations before they are released as commercial varieties.

- Anthelminthic BFT Trial: Digestive tract parasites are a major limiting factor in yields of meat, milk and fiber from sheep and goats. Parasites on many farms are resistant to conventional dewormers. Birdsfoot trefoil has demonstrated potential as a medicinal forage in laboratory tests, with varieties differing in effectiveness. Trefoil is a high quality feed for sheep and goats even in the absence of parasites, and it improves soil quality. We are evaluating eight varieties over three years to find the best combination of effectiveness and forage yield. Identification of a superior variety will allow sheep and goat producers to improve herd health and yields while reducing dependence on conventional dewormers and improving soil quality.

We met in conjunction with the North American alfalfa improvement conference. We received reports on the range of our activities, and received an update on the renewal proposal to NE1710, the now accepted NE2210. We have made good progress in developing regionally adapted pools of alfalfa germplasm. COVID-related delays to our trefoil activities have eased, allowing the processing of digestible fiber that had been slowed. Cool season grass development continues. Development of switchgrass germplasm has led to two germplasm releases in process in Mississippi. All projects are moving forward.
