玉米品质性状的遗传模型分析

Analysis of Genetic Model on Quality Characters of Maize

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。

Abstract:

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.
