Parker, Bordollo, and Colova published a paper in Acta Horticulturae in 2009 that states, based on DNA analysis, that V. aestivalis, V. labrusca, and V. vinifera are all involved in the parentage of Norton. The vinifera cultivar is ‘Chasselas’. The researchers also discovered that PD resistance is derived from V. aestivalis. They also found that Norton and Cynthiana are genetically identical, ergo, they are the same cultivar. ~ Dr. Eric Staphne, OSUTNWTnoreply@blogger.com
