‘Wyandot‐14’ soybean [ Glycine max (L.) Merr.] (Reg. No. CV‐520, PI 676304) with resistance to soybean aphid ( Aphis glycines ) biotypes 1 and 2 and resistance to powdery mildew (caused by Microsphaera diffusa Cooke & Peck) was jointly released by the USDA‐ARS and The Ohio Agricultural Research and Development Center as a late maturity group (MG) II (2.9) food‐grade conventional cultivar. Soybean aphid is a major insect pest of soybean in the United States. The objective of this research was to incorporate soybean aphid and powdery mildew resistance into the popular food‐grade soybean cultivar Wyandot. Wyandot‐14 was developed by backcrossing the Rag 2 and Rmd _PI243540 alleles for resistance to soybean aphid and powdery mildew, respectively, from PI 243540 into 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 a shiny yellow seed coat, and a yellow (clear) hilum, and it has an indeterminate growth habit. Wyandot‐14 should be an excellent replacement for Wyandot.
