|
1. Power 4.2 is a synthetic variety with 200 parent plants that were selected sequentially for multifoliolate leaf expression and for resistance to Phytophthora root rot and Aphanomyces root rot (race 1). Parent plants were selected from crosses between selections from three-year old Minnesota and Wisconsin yield trials. Yield trial source varieties were derived from various populations that were developed by phenotypic recurrent selection |
