Bernard (1971) reported on two major genes, E1 and E2, that affect the time of flowering and maturity of soybeans. Buzzell (1971) reported another maturity gene, E3; the recessive allele did not respond to fluorescent-daylength treatment. Kilen and Hartwig (1971) reported a recessive gene for a similar character in southern varieties.
