In order to breed new soybean varieties of cold region planting suited and soybean products processing needed based on continuous selection and breeding, ecological selection and advanced identification and detection, a new early-maturing with high yield and quality soybean variety of Henong 95 had been bred by parents selection, hybridized combination (Suinong 14 & Heihe 38) and selection population construction. Henong 95 was validated and promoted by national crop committee in 2016. The protein of this variety was 41.39%, fat content 18.76%, protein and fat sum 60.20%, resistance to phytophthora, medium resistance to gray spot and medium susceptibility to SMVⅠ& Ⅲ. The average yield of national regional trial was 2 781.3 kg·ha-1, which was 8.0% higher than the control variety. The average yield of national production test was 2 985.7 kg·ha-1, which was 10.0% higher than the control variety. Based on the extensive parent pedigree, clear genealogical relationships, well hereditary basis and fine cultivation technology, this variety had 493.7 thousand ha promotion area and 130 million kg increased yield, created 480 million yuan social benefit. The breeding and research results of this variety has guiding significance for the breeding and production of cold region soybean.
