Armstrong Research and Demonstration Farm
Through a grant from the Leopold Center for Sustainable Agriculture, a grape cultivar by management system trial was established in 2002 at the ISU Horticulture Research Station, Ames, and at the ISU Armstrong Research and Demonstration Farm, Lewis. The trial was designed to evaluate 15 cultivars under three management systems. In 2002, 10 wine cultivars [Maréchal Foch (Foch), Frontenac, Cynthiana (Norton), St.Croix, Chambourcin, Seyval Blanc (Seyval), La Crosse, Vignole, Traminette, Edelweiss], and four seedless table cultivars (Marquis, Vanessa, Reliance, Mars) were planted at the two locations, with the seedless cultivar Jupiter added in 2003.
