Fig. 1. Frequency distribution of total isoflavone content in soybean seeds for three recombinant inbred line (RIL) populations grown in 2000 (white bars): a) Harovinton x OAC Arthur (n = 98), b) AC756 x OAC Arthur (n = 101), and c) AC756 x RCAT Angora (n = 187). The RILs selected for the 2002 growing season are represented by bars filled with diagonal or horizontal lines. Phenotypic classes selected were RILs containing high, intermediate, and low total isoflavone content in the seed.
