Abstract:

Soybean varieties were selected for sexual hybridization from different soybean lines with different soybean varieties. Generation of organisms from which hybrid offspring are produced by pot culture, disease nursery experiment, quality trace analysis and oriented selection. Six new soybean germplasm Qingnong 05-1028, 05-1009, 05-1071, 07-1115, 07-1568 and 08-2535 was selected. They possessed good agronomical characteristics of resistance to race 1, 3 of soybean cyst nematode, high oil (fat content more than 22%), high yield and good quality. Therefore, it should be adopted in soybean quality genetics and breeding program for extensive genetic base.
