Abstract: In this study, we used Heinong 37(Glycine max), ZYD581(Glycine soja) and their F2 and F3 as materials to locate the QTL of soybean nodes of main stem and analyze its genetic effect. The soybean genetic linkage map including 3 linkage groups was drawn, located 1 QTL related to soybean nodes of main stem on chrl linkage group. In 2007, this QTL was located between Satt238 to Satt242, the genetic distance was 0.01 cM from Satt238, 24.69 cM from Satt242, the genetic contribution rate and additive effect was 17.22% and -3.2608, respectively. In 2008, it was located between Satt240 to Satt238, the genetic distance was 0.59 cM from Satt238, 6.01 cM from Satt240, the genetic contribution rate and additive effect was 6.68% and -1.4965, respectively. The results of two years analysis showed that there were 1 QTL related to soybean nodes of main stem near Satt238.
