hybridized combinations of soybean, whose parents from China, America, Japan and Korea respectively were studied on genetic variation of agronomic character in F 2 generation. The results showed that: 1) There are higher genetic variation on 100 grain weight and main stem branch.2)Several agronomic characters of different combinations show high positively hybrid vigor and the heritability of 100 grains weight and number of branch were relative higher. 3)GS and RGS of number of branch and first node on branch were relative higher, for which means bright future.
