AbstractEarly maturing varieties of soybean are low yielding due to their small plant stature and short vegetative period. The objective of this research was to develop early varieties of soybean with extended days to flowering while keeping the days from flowering to maturity intact. Crosses were made between two early (CM2 and NS1) and two late (CB1 and LJ4) maturing varieties. Conventional and modified single seed descent methods were used to select for late flowering but early maturing relative to the early maturing parents. Eleven selected lines were tested for three seasons using two early maturing parents and SJ5, a medium maturing variety, as the standard check and it was found that four lines, C-3108, M-3213, M-3215, and M-3217, outyielded both early parents and the standard check, SJ5. These lines gave more days to flowering than the early maturing parental checks, but the days from flowering to maturity were similar to the early checks. The correlation between the yield with days to maturity was not important but with days to flowering it was significant. This experiment showed that the extension of days to flowering resulted in an increase of the yielding potential of early maturing soybean
