In conjunction with the Northeast Regional Research Project NE-1020 “Multi-state Evaluation of Wine Grape Cultivars and Clones,” Iowa State University (ISU) established a cold-hardy wine grape cultivar trial in 2008 at the ISU Horticulture Research Station (HRS), Ames, Iowa. The Iowa trial evaluates the performance of Corot Noir, La Crescent, Marquette, Petit Ami™ (planted in 2009), NY95.0301-01 (Arandell), MN1189, MN1200, MN1220, MN1235, MN1258, with Frontenac and St. Croix serving as control cultivars. Selection NY95.0300-01 (Aramella) was shipped by mistake and was planted in the guard rows and as end-of-row guard vines and Louise Swenson was used as replacement plants in blocks containing MN1235 vines that died (results not reported here). This report summarizes the results for the 2017 growing season.
