Two independent gene pairs affecting time of flowering and maturity in soybeans ( Glycine max (L.) Merr.) were identified and studied in a common genetic background developed by backcrossing to the commercial variety ‘Clark.’ E 1 , a gene for lateness linked to pubescence color (T t) , was transferred from strain T175, and e 2 , a gene for earliness, from T245. The late allele at each locus was partially dominant in most combinations. Flowering and maturity dates for the homozygotes based on 2 years data at Urbana, Ill., are summarized below as number of days earlier (−) or later (+) than Clark.Strain Genotype Flowering MaturityClark e 1 E 2 0 0 Clark‐E 1 E 1 E 2 +23 +18 Clark‐e 2 e 1 e 2 − 7 −14 Clark‐E 1 e 2 E 1 E 2 + 9 + 1
