摘　　要：用302D和黄爆粒玉米配成杂交种混粉与黄早四杂交,分别回交1～2次,以此为原始材料组建小群体。交替运用自交选系和群体轮回选择方法,育成早熟、高配合力、抗病性强和综合农艺性状好的玉米自交系武314。用其组配的杂交种早熟、抗逆性强、适应性广,因而被全国各地广泛应用,成为我国玉米育种中重要的早熟种质资源之一。Wu314 inbred line was bred by the inbred line with high-combining ability Huangzaosi and material with 302D and popping corn germplasm. The authors had integrated the recurrent selection in corn strain population with the pedigree method. Wu314 inbred line and the hybrid maize varieties combined with it are extensively in all over China because it has early maturity, high combining ability, high resistance to disease and the superior comprehensive agronomic properties. Wu314 inbred line played significant roles in the maize breeding.
