Abstract: To breed new soybean varieties with high oil content and high yield, enhance the production advantage and market competitiveness of oil extraction soybean, a new high oil content and high yield soybean variety‘Henong72’was bred by analyzing parental genealogy and kinship, genes and character inheritance and the parental using effects, to select excellent parents, arrange hybrid combination, establish selection population and to optimize design of breeding technology and detection. This soybean variety was validated and promoted by Heilongjiang Provincial Crop Committee in 2018. The oil content is 23.42%. The average yield of regional trial is 3099.1 kg/hm2, 13.0% higher than that of the control variety‘Henong51’. The growth period is 115 days approximately and the active accumulated temperature ≥10℃ is 2300℃. The variety is suitable for planting in the mid- early maturing producing area of northern spring soybean, and has medium disease resistance to gray spot.
