The number of flowers and pods were investigated in order to make clear the characteristics of the flowering and pod set as affected by raceme order for the late-maturing soybean cultivar 'Fukuyutaka' which was widely cultivated in south-west Japan. Seeds derived from the lower-order racemes (terminal and primary raceme) accounted for the majority of the yield in the early-maturing cultivars, whereas in Fukuyutaka, a late-maturing cultivar, seeds derived from the higher-order racemes (secondary raceme, secondary raceme with compound leaves and tertiary raceme) exceeded those from the lower-order racemes. It contributed to the increase in the number of flowers and the raise of the pod set ratio on the higher-order racemes. These results indicated that flowering and pod set on the higher-order racemes affects the seed yield significantly in the late-maturing soybean cultivars.
