摘　　要：根据中国玉米杂交优势利用模式,对武109自交系用含唐四系、旅系种质的自交系进行了改良研究、自交选系。结果表明:选育的自交系8126一般配合力高,在5.77万株/hm2下测配新组合大穗大粒,抗病抗倒,结实性好,高产稳产,开发前景较好。According to the model of China maize hybrids, the Wuzi maize inbred line was improved by the inbred line which contain the germ plasm of Tangsi line and L?line The results indicate that the new inbred line 8126 possess high G.C.A. The new hybrids from 8126 have some features, such as: big ears and kernels, strong disease resistance , stiff straw, and high seeds setting percentage . As the same time, the hybrids show high and stable grain yield under 5.77×104 plants/hm2. So, the new hybrids could be a good maize variety to devehop in future.
