Fig. 5. Soybean Genotype selection on the basis of a GT biplot. (A) Selection on the basis of seed yield; (B) selection on the basis of oil and protein concentration; (C) selection on the basis of oil concentration and seed yield; (D) selection on the basis of protein concentration and seed yield; and (E) selection on the basis of oil yield and protein yield. DTM = days to maturity, HEIGHT = Plant height, KW = 100 seed weight, LODG = lodging scores, OIL = percentage of oil, PROTEIN = percentage of protein, YLD = seed yield, YOIL = oil yield per unit land area, and YPROT = protein yield per unit land area.
