1. Stine 9227 is a synthetic variety with 113 parent plants. Parent plants trace to three populations selected for resistance to the following pests: bacterial wilt, Fusarium Wilt, Verticillium wilt, Phytophthora root rot, anthracnose and Aphanomyces. Phenotypic recurrent selection was used. Selections were made from a Aphanomyces/Phytophthora root rot evaluation nursery near Marshfield, WI based on winter survival, vigor and root size and health. Parentage of Stine 9227 traces to Apollo Supreme (68%), and Arrow (32%). Approximate germplasm source contributions are: M. Falcata (7%), Ladak (8%), M. varia (22%), Turkistan (16%), Flemish (38%), Chilean (5%) and Peruvian (4%).
