Soybean [ Glycine max (L.) Merrill] lines selected for differences in oil percentage from BC 1 and BC 2 populations were evaluated for seed yield, oil percentage, and protein percentage. Selection on the basis of oil percentage was effective in obtaining lines distinctly different in protein percentage. High‐protein lines averaged lower yields than did high‐oil lines. All BC 1 lines averaged lower in seed yield than BC 2 lines. Evidence is presented to show that factors other than chemical composition have influenced the seed yield level of the lines selected.
