The white grape variety (also New York 10513 and NY 10513) is an interspecific new variety between Lignan Blanc(Luglienga Bianca) x Ontario. It contains genes from Vitis labrusca and Vitis vinifera. The hybrid was crossed in the USA in 1917. The early-ripening, frost-hardy variety is susceptible to powdery mildew; the berries have a foxtone. It was a cross between the two new varieties St. Croix, Vanessa and Vincent. The variety is widespread in the northeastern USA and Canada, where it is used as a wine press and table grape. However, no stocks were reported in 2010 (Kym Anderson).
