Duration of reproductive phase (R1–R7), in growing degree days, of 15 near-isogenic lines (NILs) grouped by number of dominant E-gene alleles (E1 counted as 2 dominant alleles), planted either early or late in a) 2003 and b) 2004. The bars represent standard error of the means.

Average ambient photoperiod (includes civil twilight), experienced by 15 near-isogenic lines (NILs) grouped based on number of dominant E-gene alleles (E1 counted as 2 dominant alleles), during their respective R1 to R5 stage of development under an early and late planting-date treatment. Data are averaged over 2003 and 2004. The bars represent standard error of the means.

Duration of the reproductive phase (R1–R7) in growing degree days of seven soybean near-isogenic lines (NILs) grouped based on number of dominant E-gene alleles (E1 counted as two dominant alleles), and grown in A) 2004 and in B) 2005. The bars represent standard error of the means.
