0PI 676304'Wyandot-14'Glycine max (L.) Merr. SOYFlower2016DEVELOPED03/15/2016CultivarWyandot-14 soybean with resistance to soybean aphid (Aphis glycines) biotypes 1 and 2 and resistance to powdery mildew (Microsphaera diffusa) was jointly released by the USDA-Agricultural Research Service and The Ohio Agricultural Research and Development Center as a late maturity group II (relative maturity 2.9) food-grade conventional cultivar. Wyandot-14 was developed by backcrossing Rag2 and Rmd_PI243540 alleles for resistance to soybean aphid and powdery mildew, respectively, from PI 243540 into cultivar Wyandot. Compared to Wyandot, Wyandot-14 showed no yield drag in the absence of soybean aphid and/or powdery mildew pressures. In soybean aphid infested fields, Wyandot-14 had significantly (p<=0.05) higher yield than Wyandot. Like Wyandot, Wyandot-14 has white flowers, gray pubescence, brown pods, round seed with shiny yellow seed coat and a yellow hilum and it has an indeterminant growth habit.1938205PI 676304
