Brief Summary of Minutes

Brief summary of minutes from annual meeting:


The Annual Technical Committee meeting was hosted by Dan Ward of Rutgers/NJAES in Cape May, New Jersey on 14-15 Nov. 2017. Meeting was called to order with brief introductions and call of states was immediately followed by formation of subcommittees. Much of the planning for the project was framed by the establishment of the new subcommittees and the discussion of the charges of each subcommittee.


The Viticulture committee was charged with revising NE1020 protocols for use by all participants. Viticulture discussion included wine making concerns especially for participants without enology facilities at their institutions. Enology collaborators may be used as long as a uniform protocol (as adopted by NE1020 previously) is followed. Screening Trials and Evaluation Trials will use the protocol developed by the viticulture committee. An additional category (not included in proposal for project) of trials unique to each participant was created to include coordinated reporting of these unique cultivar trials to the NE1720 committee. Provisional category name to be Coordinated Exploratory Trials.


The Data Collection committee was charged with developing standardized data collection protocol and tools. The possibility of a web-based data collection mechanism was discussed and will be further considered by the committee, but until further notice the use of a standardized spreadsheet for data entry and submission was encouraged. The use of weather data from stations not in direct physical proximity to each research vineyard was proposed and investigation of this option charged to the committee. A small set of response and environmental variables will be established as requirements for each participating site to minimize costs and maximize generalizability of results. Annual report was decided to specifically require a list of all varieties under test as part of the NE1720 by each participant.


The Outputs and Milestones committee was charged with planning and coordinating publications and group outputs. Using the data from the previous NE1020 perhaps in conjunction with new NE1720 data to produce peer-reviewed publication of group results rapidly was proposed and acceptable as a goal. Web-based and journal-based publications will be explored. The use of the existing websites for more rich and attractive presentations will be investigated. If new alternatives need to be used, they will be investigated as well. The outputs need to emphasize the value of descriptive research to generate and develop hypotheses for further research. A searchable database that summarizes results will be considered.


The Germplasm and Discovery committee was charged with identification of new lines (especially new materials from breeding programs), deciding how many new lines to evaluate from breeding programs, and assisting in arranging details of materials transfer agreements. Discussion of new lines revealed that for new lines from breeding programs perhaps five or six sites could receive enough vines for their Screening Trials. Each breeder needs lead time to produce the vines. Once a line to test is identified, there should be enough ready for testing in two to three years.


A discussion of promising new cultivars or selections from breeding programs or elsewhere was held. The Foundation Plant Services recently moved the National Grape Registry on the web and improved it. The site provides information on clones, nurseries where they are available, and whether they are 2010 Protocol or not. Cultivars imported by Rutgers are now available through FPS (and soon through a commercial nursery) including Casetta, Schiava grossa, Merlot clone 88BM, and Nebbiolo Chiavennasca clone. For newest cultivars being tested the critical result was agreed to be whether or not it had survived at each site.


Discussion led by Administrative Advisor Brad Hillman elucidated much of how funds flow into multi-state projects, the importance of continuity among participants, the value of training the younger researchers during their participation in the group, and explaining the broad goals and how each state’s contribution adds to them. Participants were advised to keep deliverables as a foremost goal using web-based, publicly-available outlets to disseminate results and outputs.


Locations for the next two Technical Committee Meetings were decided: Missouri in 2018 and Minnesota in 2019.

Accomplishments

<p><strong>Accomplishments: </strong></p><br /> <p><strong><em>Short-term Outcomes:</em></strong> Subcommittees of the participants were formed to divide the work of the project. The committees created were: Viticultural Practices (chair: Joe Fiola), Data Collection (chair: Dan Ward), Outputs and Milestones (chair: Tim Martinson), and Germplasm and Discovery (chair: Matt Clark).</p><br /> <p><strong><em>Outputs:</em> </strong>Nothing to report at this time</p><br /> <p><strong><em>Activities: </em></strong>Meeting attendees learned of the wine potential of numerous global cultivars that are not widely produced in the eastern U.S., but that may have significant potential for grape growers in the eastern U.S. During a discussion and a structured tasting exercise with wines (grown and vinified in Maryland by Joe Fiola) of these underutilized cultivars researchers learned of their potential for production in new regions and became more familiar with their properties. Among the cultivars presented were: Colombard, Gr&uuml;ner veltliner, Piquepoul blanc, Rousanne, Verdejo, Verdelho, Vermentino, Petite manseng, Gamaret, Garanoir, Dolcetto, Sous&atilde;o, Teroldego. Researchers also learned of the importance of nitrogen nutrification during fermentation and its effects on flavor by use of a tasting of Reisling wines with different Nitrogen nutrient supplies (presented by Anna Katherine Mansfield). The importance of uniform winemaking protocols for isolating the effects of cultivar and allowing comparisons to be made among wines was understood more thoroughly and the need for standardization of methods was agreed upon.</p><br /> <p><strong><em>Milestones: </em></strong>As planned for Objective 1, a discussion of promising new cultivars was held that covered some cultivars from the NE1020 project trials, some recently imported cultivars, and some new selections from breeding programs. This included the newly available Casetta (imported from Italy), Schiava grossa, Merlot clone 88BM, and crosses of Teroldego x Lagrein (from the breeding program of Marco Stefanini and imported from Italy). The publication of cultivars newly available through the Foundation Plant Services was announced to researchers.</p><br /> <p>As planned for Objective 3, a subcommittee was created to organize the identification of new lines to disseminate to the other NE1720 researchers, how many lines to evaluate, and details of materials transfer agreements.</p>

Accomplishments

<h2><strong>Accomplishments</strong></h2><br /> <p><strong>Short-term Outcomes:&nbsp;</strong>Evaluation of materials at individual sites has resulted in new testing arrangment opportunities. Martinson (NY) and Clark (MN) have identified new selections/clones for testing. Data from NE1020 are being published in some cases (Iowa State, Schrader et al 2019, Hort Tech). Information is being used by the breeders in making varietal selection decisions.</p><br /> <p><strong>Outputs:</strong>&nbsp;State reports were submitted and shared with all attendees and invitees via a Google Drive link.&nbsp;</p><br /> <p><strong>Activities:</strong> Tour of NE1720 Host research plots at Horticultural Research Center, Excelsior, MN. Visited research winery as well as Kiwiberry (Actinidia sp.) production/breeding plots.</p><br /> <p>Tour of commercial cidery: Sweetland Orchard, Webster, MN as part of Joint tour schedule with NCCC212 participants.</p><br /> <p>Tour of winery and coordinated wine tasting of cold-hardy wines (UMN varieties) at Sovereign Estate Vineyard, Waconia, MN. Tour of vineyards by Isaac Savaryn, vineyard manager</p><br /> <p>Coordinated tasting of UMN advanced breeding lines (table and winegrapes) that can be made available for NE1720 participants. The structured tasting was led by A Horton and M Clark.</p><br /> <p>A summary of slides was presented from Tim Martinson, including grapevine selections available for NE1720 from the Cornell (Reisch) breeding program.</p><br /> <p>Discussed collaborations and expansion of currently funded projects to build on expertise in the group. Will incorporate microbiome study into &ldquo;Terroir&rdquo; study being conduced by Clark and Hatterman-Valenti conducted by Hall.</p><br /> <p>Suggested additional monitoring of winter injury throughout growing season to characterizing acclimiation/deacclimiation in response to varied weather stress (GxE) at all sites monthly.</p><br /> <p>A short dicussion was held on the use of the previous NE1020 Data. Martinson (via email and phone) indicated that there may be opprotunities for the USDA Breeding Insight Group to work with this historic data.&nbsp;</p><br /> <p><strong>Milestones:</strong> Reports by Fennell (SD) and Fitch-Dietz that new sites have been established and there are vineyard spaces available for additional test selections. At Kansas, the winery incubator is now operational which will allow wines to be made from test materials (Obj 2). Materials of MN1220; MN1280; MN1369 have been distributed to several test sites in 2019. Additional Cuttings available. One or more Minnesota selections have been identified for variety release and the commercialization process has been initated.</p>

Brief Summary of Minutes

The Viticulture and Enology Program of Highland Community College, Wamego, KS, hosted the annual meeting of NE1720: Multi-state Coordinated Evaluation of Winegrape Cultivars and Clones on November 9, 2020. Due to COVID-19 travel restrictions, the annual meeting was hosted virtually. Scott Kohl chaired the meeting, Matt Clark served as the meeting secretary. Present members reported on current research activities and industry impacts, within their respective states, which fulfill the objectives of NE1720. Additional discussion focused on project renewal, objectives and methods for accomplishing those objectives, and jointly planned and executed multi-state projects. In staying with NE1720 governance of Chair/host location-rotation, Maryland is the proposed Chair/host location for the 2021 meeting with Kansas as the backup location.

Accomplishments

<p>The efforts of the NE1720 participants to meet the milestones identified in the original project proposal are collaborative with the built-in flexibility for independent assessment of niche selections based on regional needs. &nbsp;During 2019-2020 numerous ventures were started and/or completed by NE1720 participants resulting in a large mass of information. These annual accomplishments are reported individually by each participant, in the form of a state report. These comprehensive reports can be viewed by accessing the annual meeting minutes file located in the Summary of Minutes section.</p><br /> <p><strong>Objectives of NE1720:</strong></p><br /> <ol><br /> <li>Screen the viticulture characteristics of clones, cultivars and elite germplasm with significant potential throughout the USA.</li><br /> <li>Evaluate the viticultural and wine attributes of promising emerging cultivars and genotypes based on regional needs.</li><br /> <li>Conduct explorations of new germplasm and lesser-known cultivars that may have economic potential for the US wine industry.</li><br /> </ol><br /> <p>&nbsp;</p><br /> <p>The following is a partial highlight of accomplishments made by NE1720 during 2019-2020.</p><br /> <ul><br /> <li><strong>Short-term Outcomes: </strong>Through the evaluation of grape varieties, in Indiana, grape specialists are recommending that industry stakeholders plant Petite Pearl as an alternative to planting Marquette, due to its ability to avoid frost injury. In Colorado, record cold events at the beginning and end of the dormant season resulted in yield reductions of 50% or more compared to the 2019 season, indicating that many primary buds were killed and much of the crop came from secondary shoots with lower cluster numbers and reduced average cluster weights. Industry stakeholders want to know the best management practices to use in their vineyards. Research from Colorado State University shows that long pruning followed by shoot thinning after bud break can be used to achieve moderate yields even when primary bud damage exceeds 50%. Stakeholders following these pruning recommendations can improve fruit yields, thus resulting in an economic gain.</li><br /> <li><strong>Outputs: </strong>The participants of NE1720 published a combined total of thirty articles during 2019-2020 and spoke at sixteen industry stakeholder meetings or conferences. Participants submitted annual state reports via Google drive and attended the 2020 meeting via Zoom. These documents and Zoom meeting recording are available for current and future use by the NE1720 collaborative.</li><br /> <li><strong>Activities: </strong>Research is underway to establish a replicated trial of grapevine cultivars infected with no viruses, GRBV, GLRaV-3 or the combination of GRBV with GLRaV-3. The results will have important implications for Missouri grape growers since a recent survey of commercial vineyards throughout Missouri determined that GLRaV-3 and GRBV were present in 53% and 35% of the samples, respectively. Yet, most all infected grape cultivars except Crimson Cabernet (Norton x Cabernet Sauvignon) do not display typical GRBV or GLRaV-3 symptomology as documented in Vitis vinifera cultivars. At the University of Nebraska specific cultivars and selections &ndash; e.g. Marquette, Petite Pearl, La Crescent, Frontenac and Itasca &ndash; have been evaluated for both viticultural and wine attributes, the latter in collaboration with scientists in the UNL Department of Food Science and the Food Processing Center (Doctor Xu and Doctor Xie).</li><br /> <li><strong>Milestones: </strong>New NE1720 participating vineyard sites in Kansas, South Dakota, and Michigan with vineyard expansion in Iowa and Nebraska. Juice data for Marquette, Frontenac, Brianna and LaCrescent from established NE1020 and Cooperative Garretson, SD vineyard monitored for 2017, 2018, and 2019 is being summarized for outreach publication by South Dakota State University. Similar juice and must data was published online by Highland Community College for grape and wine industry stakeholders in Kansas. &nbsp;Six selections of interest have been offered to all members of NE1720 from the Reisch breeding program at Cornell. Two irradiated clonal selections of Vignoles from Cornell have been grafted by Double A Vineyards and are ready for distribution to NE1720 participants in 2021. The University of Minnesota grape breeding program advanced one selection, MN1220, for variety release and has been distributed to nurseries.</li><br /> </ul><br /> <p><strong>&nbsp;</strong></p><br /> <p>In the coming year, NE1720 participants will continue collaborative efforts to plant or replant new grape selections. Two irradiated clonal selections of loose cluster Vignoles will be shipped to NE1720 participants for establishment and evaluation next to &ldquo;standard&rsquo; Vignoles.&nbsp; Additional advanced grape selections will be sent from participating breeding programs to NE1720 participants with planting sites. &nbsp;Fruit and wine evaluation continues with participants collecting annual data to be analyzed, collated, and disseminated to stakeholders. Participants have formed a sub-committee to pursue a project renewal with a focus on multi-state objectives and approaches to meet those objectives. The annual NE1720 meeting is to be held in November 2021.</p><br /> <p><strong>&nbsp;</strong></p>

Brief Summary of Minutes

Brief Summary of Minutes of Annual Meeting


The Annual Technical Committee meeting was co-hosted by Dean Volenberg of the University of Missouri Grape and Wine Institute, Columbia, Missouri and Mathew Clark of the University of Minnesota on 8 November 2021. The meeting was conducted virtually. Meeting was called to order and the meeting agenda presented. This was followed by brief introductions of attendees. The morning session consisted of state reports and Margaret Smith provided guidelines and deadlines for the grant proposal reapplication process. The afternoon session was devoted to clarifying objectives for the reapplication of the grant proposal entitled “Multi-state Coordinated Evaluation of Winegrape Cultivars and Clones”.


 


Data Collection Committee


Tim Martinson provided an update on the data collection committee. One of Tim’s goals was to establish a website that would include pertinent data generated from NE-1020 and NE-1720.


Although, Tim is retiring in early January 2022, he still has gone out of his way to help the NE-1720 group find an alternative to complete his goal.  Shortly after the Annual NE-1720 meeting, Tim contacted Matt Fidelibus at UC Davis about the potential of a collaborative database. Currently, Matt and some of his colleagues have developed a website that consists of cultivars of wine, table, raisin, and rootstocks focusing on Vitis viniferawith the goal of adding approximately 20 descriptions per year. This extension undertaking is being funded by NGRA under the NGRA extension chair Keith Striegler.  Matt is interested in a collaborative website that includes the NE-1720 data with the caveat if the NGRA is interested.


If the collaborative website moves forward or the NE-1720 group establishes their own website, the Data Collection Committee needs to determine the outputs.


Once again, the main question that needs to be addressed is what information on the cultivars evaluated in the NE-1020 and NE-1720 would be helpful to current and future grape growers.


 


Germplasm and Discovery Committee


In 2021, Missouri and Kansas established two selections of “loose clustered” Vignoles cultivars as well as the standard Vignole as a comparison. Tim Martinson presented information on the availability of irradiated Vignole germplasm at the annual meeting in 2018.  Briefly, a number of Vignole mutants were evaluated based on loose cluster architecture. Mutants were developed by Amanda Garris of the USDA. Approximately 1000 mutants were evaluated of which nine were selected for replicated trials. From these trials, Tim suggested that two mutants be evaluated in replicated trials in interested NE-1720 states. The propagated material was made available through Double A Vineyards in 2021. This is in congruence with the Objective 3 milestone: Propagate and receive cuttings for plantings at collaborator sites.


Joe Fiola suggested other grape materials for evaluation.


Matt Clark provided an update on potential breeding lines for evaluation. The advanced selection MN-1220 will likely be released soon. MN-1220 is a white wine grape for more southern climates compared to Minnesota. The Minnesota grape breeding program is also developing seedless table grape lines that may have a dual purpose for both fresh consumption and the wine industry.


Tim Martinson on behalf of Bruce Reisch also provided an update on selections from Cornell and are included in Tim Martinson’s state report for New York. Briefly,



  • 0207.02 – White wine grape

  • 0207.06 – White wine selection

  • 0208.09 – White wine grape

  • 0303.02 – White wine grape

  • 0514.06 – This is a highly disease resistant red wine selection


Missouri planted four of the NY selections in 2021. These selections are being made available by Amberg Grapevines.


NY03.0207.02 – This white wine grape has scored very well in wine tastings, with panelists mentioning bright acidity with notes of citrus, melon, apricot and peach. The vine has an excellent large canopy, some leaf phylloxera, and will need protection from bird depredation. The prediction for 50% bud kill is -15.7°F.


NY03.0207.06 – This white wine selection produces a good canopy with moderate resistance to foliar powdery and downy mildews. Fruit are mostly rot-resistance but some sour rot has been noted in some years. Wines have been highly ranked by tasting panels, with aromas described as melon, pear, spicy and pineapple, while the palate descriptors included good structure and body; and mentions of citrus, pineapple apple and Riesling-like characters. The predicted temperature for 50% bud kill is -16.9°F.


NY03.0208.09 – This white wine grape has been described as having citrus, tropical fruit, peach and pear characteristics in both the aroma and palate. It has been very well-liked by tasting panels. Vines have been moderately productive with good resistance to powdery mildew. Bird damage has been a problem and protection (netting) is needed. Some years, rachis necrosis was noted just prior to harvest. The predicted temperature for 50% bud kill is -15.4°F


NY04.0303.02 –This is a white wine grape, which produced the top–ranked white wine from vintages 2013 and 2016. Wine descriptors included muscat, peach, spicy, tropical fruit, mango, grapefruit, dried apricot, lychee, and passion fruit. The 2016 wine had Sauvignon blanc-like tropical fruit and green notes. These vines are productive and vigorous so far, with good resistance to downy and powdery mildews under a hybrid-type spray program. The predicted temperature for 50% bud kill is -15.5 °F.


NY06.0514.06 – This is a highly disease resistant red wine selection. This selection carries the Run1 / Rpv1 genes, as well as Ren2 (for powdery mildew resistance) from V. cinerea. Also has excellent resistance to bunch rot, and moderate resistance to black rot. The buds are moderately winter hardy, with expected temperature of 50% bud kill in mid-winter measured to be -16.4°F. Vines are on the small side and grafting on phylloxera-resistant stocks should be tested. Fruit yields are low, due to the use of many clusters for crossing each year. Wine descriptors are as follows: fruity with notes of blackberry, plum, cherry; slightly herbaceous, with green pepper noted; good body and medium tannin; also, some have detected chocolate notes.


Afternoon Session: Hosted by Matt Clark


The afternoon session focused on defining the objectives for the grant proposal reapplication.


Attendees were randomly assigned to break-out rooms. Each break-out room discussed and clarified one of the objectives for the grant proposal reapplication. After a period of time all the break-out room attendees re-joined in the main meeting to present their objectives. A lot of time was spent discussing what data needs to be collected for screening advanced breeder selections and what data needs to be collected for a replicated trial evaluation.


One of the limitations of screening advanced breeder selections is often there is limited cuttings, rooted cuttings or grafted material. Therefore, it was decided that advanced breeder selections would be screened at four different sites (states) that would fully encompass the climatic zones of participating states. Advanced selections that meet the merits of the screening process then could be propagated or cuttings distributed to other states for a full evaluation.


Attendees that volunteered to help Matt Clark with the grant proposal reapplication process were: Horst Casperi, Dean Volenberg, Anne Fennel and Tim Martinson.


Future Annual Meeting locations will be 2022 Kansas hosted by Scott Kohl and 2023 Michigan hosted by Esmaeil Nasrollahiazan.

Impact Statements

  1. In the 1990s, there was no grape or wine industry in Vermont, but by 2016, winegrapes were grown on 165 acres and wine was valued at over $5 million annually. Continued refinement of cultivar breeding and selection for unique cold-climate regions will increase the quality of wines made and the economic impact of wineries in the region.
