A total of 113 soybean varieties from Northeast and Huanghuaihai Valleys since 1940s were selected for pedigree analysis based on their commercial success measured by their planted areas in hectares. Based on the collected pedigree data of these varieties, the end ancestors and direct parents of these varieties were traced. Compared to the data of the varieties reported before, the number of end ancestors of these popular varieties was increased, and their genetic basis was broader than ordinary varieties. Newly-bred poplular varieties had broader genetic background than the old ones. The genetic basis of these varieties from Huanghuaihai Valleys was broader than thosefrom northeast China. Their offsprings had greater potential to be new elite varieties than those from other crosses. The germplasm exchange between different regions could be further improved.
