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。
In this study, incomplete inbred lines were used to study the genetic effects of 4 quality traits on common maize by combining 10 inbred lines with 24 combinations. The heredity of lysine content accorded with additive - dominance model, starch content, oil content and protein content accorded with additive - dominance - epistasis model. The inheritance of four quality traits were all additive effects.
