摘　　要：试验采用不完全双列杂交法 ,把 10个自交系配成 2 4个组合 ,对普通玉米的 4个品质性状的遗传模型、基因效应进行了研究。赖氨酸含量的遗传符合加性—显性模型 ,淀粉含量、油分含量、蛋白质含量符合加性—显性—上位性模型 ,4个品质性状的遗传方式均以加性效应为主。Ten inbred lines of maize were tested in the incomplete parallel cross design including 24 cross sets.The genetic models,gene effects of 4 quality characters were studied.The additive_dominance and additive_dominance_epistatic genetic models were inlined with lysine content and starch、oil、protein content respectively.Additive gene effects were significantly high in 4 quality characters.
