利用４７８个种间杂交组合和３０７个回交组合进行大豆种间杂交育种技术的研究。提出亲本选配原则，克服种间杂种后代蔓生、小粒、粒色深等野生不良性状的技术；明确了种间杂种主要性状的选择潜力，在种间杂种早代性状选择、后代群体规模、回交改良时期及决选世代等方面的种间杂交选育新技术。直接利用野生大豆种质育成“吉林小粒１号”新品种，１９９０年通过吉林省的品种审定并出口创汇。利用种间杂交新技术创造出主茎有效节数２５个以上、单株荚数１５０个以上以及蛋白质含量５０％左右的直立型育种中间材料；育成一批大粒高产优良新品系，现已进入省区试或省预试。
Using 478 interspecific hybrids and 307 backcrosses, the interspecific hybridization of soybean was studied. The principle of selection of parents was proposed to overcome the undesirable traits such as spur, small grains and deep color in the interspecific hybrids. The potential of selection for the main characters of interspecific hybrids was clarified. The characters of early hybrids, the size of offspring, Pay the reform period and the election generation and other aspects of interspecific hybridization breeding new technologies. Direct use of wild soybean germplasm breeding “Jilin small grains on the 1st” new varieties, in 1990 through the Jilin Province, the variety of validation and export earnings. Using the new interspecific hybridization technology to create an effective number of main stems more than 25, more than 150 pods per plant and protein content of about 50% upright breeding intermediate materials; bred a number of large grain high yield good new lines, has now entered the province Regional or provincial pre-test.
