Qihuang 1 as one of elite summer soybean germplasm was used to develop 92 high yield and high quality soybean varieties and elite lines in 11 provinces, among which 87 varieties were from in the Huanghuaihai region in China.One of the varieties obtained the second class award of National Science and Technology Advancement, two obtained the third class award of National Invention, and two obtained the third class award of National Science and Technology Advancement. The protein content of 23 varieties were over 45%, five varieties over 46%, two varieties over 47%, three varieties over 48%, and two varieties 51%. The fat content of six varieties were over 22%, and one variety 23%. Twenty seven varieties were resistant to SMV, and seven varieties were resistant to Downy Mildew. The results suggest that elite germplasm are important for soybean breeding through promoting the efficiency of soybean breeding to select elite cross.
