In conjunction with the Northeast Regional Research project NE-1020 “Multi-state Evaluation of Wine Grape Cultivars and Clones,” Iowa State University established a cold hardy wine grape cultivar trial in 2008 at the ISU Horticulture Research Station (HRS), Ames, Iowa, and Tabor Home Vineyards and Winery (THV), Baldwin, Iowa. The Iowa trial evaluates the performance of Corot noir, La Crescent, Marquette, Petit Ami™, NY95.0301- 01 (Arandell), MN1189, MN1200, MN1220, MN1235, MN1258, with Frontenac and St. Croix serving as controls. Selection NY95.0300-01 was shipped by mistake and was planted in the guard rows and as end-ofrow guard vines. This report summarizes the results for the 2013 growing season.
