Target Audience:Variety trials and evaluations are targeted at grapevine growers, researchers, and nurserymen east of the Rocky Mountains, North America. The variety trial at LIHREC is relevant for Long Island winegrowers as well as for winegrowers throughout New York state, the northeast and mid-Atlantic regions as we assess both vinifera and hybrid varieties. Loose-clustered vignoles trials are targeted at producers in NY, Missouri, and Pennsylvania. Changes/Problems:PI Tim Martinson is retiring in early 2022. What opportunities for training and professional development has the project provided?

How have the results been disseminated to communities of interest?Over the course of the project (2018-2021) results have been disseminated through newsletters, field tours, and presentations: Wise program: 2018 Long Island variety trial. This long-running trial, managed by Alice Wise, Sr. Issues Educator with Cornell CooperativeExtension of Suffolk County, evaluates 34 varieties and clones of interest to the Long Island industry. Research summaries are posted at: http://ccesuffolk.org/agriculture/grape-program/grape-research 2019. Information about variety trials is included in several extension news outlets and a website:.

Preliminary Results from "Loose-clustered" Vignoles Clonal Trial Veraison to Harvest #5, October 4, 2019. The results of the Loose-clustered trials were presented at the NE1720 meeting in2019, 2020, and 2021, and participants were made aware of the availability of planting material from Double A Vineyards for inclusion in regional trials. At least 5 programs have expressed interest, and 3 have planted the two clones plus the standard Vignoles clone in their variety trials What do you plan to do during the next reporting period to accomplish the goals?The portion funded through Federal Capacity Funds grant program at Cornell is finished. The NE1720 project runs another year. Next year Martinson program plans on continuing evaluation and possible release of the two 'loose-clustered' vignoles clones. Plantings established in 2021 and 2022 will continue to be evaluated through 2025. A journal article about the significant reduction in cluster rots (botrytis and sour rots) in 4 years of field evaluations will be written and submitted for publication.
Impacts
What was accomplished under these goals?
1. Screen the viticulture characteristics of clones, cultivars, and elite germplasm with significant potential throughout the USA. • Reisch Program: Our role in NE1720 is to develop promising selections with commercial potential, and offer them to NE1720 participants for testing in a variety of locations. We have identified six selections of interest (four white wine, onehighly-disease resistant red wine, and one for rosé production), and have offered these selections to all members of NE1720. One offered in 2019 was eliminated due to sour rot issues. IN 2019, the program made 24 crosses resulting in >7,500 seeds and in 2020 the program made 15 crosses resulting in 5,006 seeds. Most crosses were intended to combine disease resistance genes into cold hardy, high wine quality backgrounds, and to introgress new sources of diversity from programs in Italy and Germany into the Cornell breeding program. Newly identified sources of downy mildew resistance from Vitis amurensis were incorporated into the program in 2020. We identified 47 and 44 selections of interest in 2019 and 2020, respectively, for propagation and further testing. This is more than twice the number of selections made in previous years, and reflects the high quality of recently planted seedlings due to marker-assisted selection procedures, which help us select disease resistant seedlings prior to field planting. • Alice Wise Program on Long Island: Data was generated from 37 varieties, 32 vinifera varieties and 5 hybrids. The vinifera varieties represent new and less common selections that could help growers diversify their vineyards and wine portfolios. It is essential to screen these as currently planting costs for one acre on Long Island is >$20,000, not including the land. The disease resistance and fruit quality of the hybrids is being assessed in support of sustainable viticulturee goals. These vines were treated with approximately half the fungicides of the vinifera. Also, hybrids are harvested earlier than vinifera, lessening the economic risk associated with letting fruit hang throughout the fall (avoiding losses to tropical storms, cluster rot, birds, raccoons, etc). Two vinifera selections were planted in 2019, Mencía, a versatile Spanish red, and Rkatsiteli, an aromatic white that has had some success in the Finger Lakes. In 2020, the vinifera Tannat (high tannin red) and two hybrids of Tocai Friulano were planted. TF is a high quality vinifera variety with economically unsustainable low yields. In terms of industry planting, based on our results, plantings of Albariño, Verdejo, Muscat Ottonel and Auxerrois have been done recently. One grower has expressed strong interest in NY 81, the Cayuga White x Riesling hybrid. We have had great success with NY81 - consistently good yields with low wire VSP training and excellent fruit quality with no cluster rot. • Martinson and Bates program: Eight 'Loose-clustered' clones developed by the USDA-ARS Grape Genetics Research Unit and the standard Vignoles variety were evaluated over three years (2018-2020) at a replicated trial at CLEREL laboratory in Western NY. In 2020, the incidence and severity of late-season rots (botrytis bunch rot an sour rot) were again evaluated. Fruit rot incidence in two clones selected for propagation, R65V83 and R67V79, was reduced by over half (40% vs 90% in standard Vignoles), and severity was reduced by 78% in both clones (8% vs 37% in standard vignoles). These two selections were grafted to 3309 rootstock and released to NE1720 cooperators and planted in 2021. An additional larger commercial planting is slated for 2022. The Bates program also has a planting of 'early Concord' from Brazil, that has entered its 3rd year and produced fruit for the first time. Ripening was advanced by ~2 wk compared to standard Concord. 2.Evaluate the viticultural and wine attributes of promising emerging cultivars and genotypes based on regional needs. • Reisch and Mansfield programs: Advanced selections are evaluated annually for wine quality. • Wise program: Wine attributes are evaluated in two ways. An annual field tour (Plant Science Day) with ends with a 'grape tasting' where industry members can sample and discuss impressions. In 2019, Albariño and Vermentino were winemaker favorites. During the 2019 harvest, we gave fruit to several winemakers for small lot winemaking. While we have not been able to have a wine tasting, several bottles have been shared with winemakers. Vermentino, NY81, Saperavi and Regent have received favorable reviews. Though wine supplies are limited, we will continue to share in this manner as inperson tastings may not take place for another year or so. • Martinson and Mansfield programs: Four selections were vinified in 2019 (single lots) and 2020 (duplicate lots). Sensory discrimination testing by the Cornell Consumer Sensory Research Laboratory was conducted in August, 2021. The two 'loose clustered' clones were compared to the standard Vignoles clone. Minor sensory differences (aroma) were detected by a consumer panel.

What was accomplished under these goals?
1. Screen viticultural characteristics of clones, cultivars, and elite germplasm. Reisch Program: Our role in NE1720 is to develop new elite selections with commercial potential, and offer them to NE1720 participants for testing in a variety of locations. We have identified seven selections of interest (five white wine, one red wine, and one for rosé production), and have offered these selections to all members of NE1720. Two commercial nurseries are propagating these selections to make larger quantities of planting stock available. Also, in 2019, the program made 24 crosses resulting in >7,500 seeds. Most crosses were intended to combine disease resistance genes into cold hardy, high wine quality backgrounds, and to introgress new sources of diversity from programs in Italy and Germany into the Cornell breeding program. We identified 47 selections of interest among recent seedlings for propagation and further testing. This is more than twice the number of selections made in each of the previous two years, and reflects the high quality of recently planted seedlings due to marker-assisted selection procedures, which help us select disease resistant seedlings prior to field trials. Alice Wise program on Long Island: Data was generated from 35 varieties, 32 vinifera varieties and 3 hybrids. The vinifera varieties represent new and less common selections that could help growers diversify their vineyards. It is essential to screen these as currently planting costs for one acre on Long Island is >$20,000, not including the land. The disease resistance and fruit quality of the hybrids is being assessed in support of sustainable viticulture goals. These vines were treated with approximately half the fungicides of the vinifera; consequently, if viticultural characteristics are favorable, hybrids may be a low impact option. Two vinifera selections were planted in 2019, Mencía, a versatile Spanish red, and Rkatsiteli, an aromatic white that has had some success in the Finger Lakes. Martinson and Bates Program: Eight 'Loose-clustered' clones developed by the USDA ARS unit at Geneva and the standard Vignoles clone were evaluated for the second year at a replicated trial at CLEREL laboratory in Western New York. Cluster compactness, and incidence/severity of fruit rots (botrytis and sour rot) were evaluated in September. All eight clones had significantly reduced levels of fruit rots compared to the control. Cluster weight was reduced significantly in some of the clones, but four were selected for winemaking following the 2018 growing season. Virologist Marc Fuchs tested these four for virus, and found that two of the selections tested positive for grapevine leafroll virus-3. The two remaining clones will be propagated this winter and grafted for planting at 3 NE1720 sites in 2021. An early-ripening Concord clone from Brazil is in its 2nd year (non-bearing) at the CLEREL laboratory. 2. Viticulture and wine attributes: Reisch program: Advanced selections are evaluated annually for wine quality. Wise program: Wine attributes are being evaluated in two ways. The fruit tasting in September, 2019, allowed growers to directly compare 20 varieties. At harvest, fruit from 10 varieties was provided to three local winemakers for small lot winemaking. This will provide winemakers with a preview of potential wine quality as well as winemaking challenges. Martinson Program: Four selections were vinified by the Anna Katharine Mansfield program, and a summer scholar conducted a wine tasting trial, using 'difference testing'. 35 panelists rated wines made from the four clones and the 'standard' vignoles clone. No significant differences in sensory attributes were found. Additional lots of wine were vinified from the 2019 crop for industry tastings later.

NE1020 block at Geneva. Yield data was taken last in 2017. The vineyard is now being used in collaboration with Dr. Jason Londo for cold-hardiness monitoring and modeling from the 10 varieties planted there. 2. Long Island variety trial. This long-running trial, managed by Alice Wise, Sr. Issues Educator with Cornell Cooperative Extension of Suffolk County, evaluates 34 varieties and clones of interest to the Long Island industry. Research summaries are posted at: http://ccesuffolk.org/agriculture/grape-program/grape-research 3. Loose Clustered Vignoles. Vignoles canes subjected to radiation to induce mutations that would result in loose clusters were made into single-bud cuttings (N= ~1000) in the early 2000s by USDA scientist Amanda Garris. These were planted at an experimental vineyard at the Cornell Lake Erie Research and Extension laboratory (CLEREL) in Portland NY. From these vines, 19 'loose-clustered' clones were propagated and grafted for plantings at Cornell AgriTech (2014) and at a larger, replicated trial at CLEREL, along with the 'standard' Vignoles clones. Harvest evaluations in 2016, 2017, and 2018 showed reduced cluster compactness (g wt/cm of rachis) and significantly reduced fruit rots (Botrytis and sour rot) among all the clones compared to the standard. Harvest evaluations in 2018 at the CLEREL laboratory showed similar results, and experimental wines were made from 6 different clones and the standard Vignoles clone. They will be evaluated in 2019 via triangle tests, to test whether the clones show typical Vignoles flavor profiles. This is the first cropping year, but 3 of the clones look promising in reducing cluster compactness, while maintaining adequate yield. We hope to propagate some and distribute to NE1720 cooperators. 4. Proposal for Posting NE1020/NE1720 data for a broader audience. Data from the NE1020 trials, starting in 2010 have not been jointly posted in a format that would be accessible to extension associates and industry.
