| 摘 要： | 大豆粒形直接与产量相关,对其粒长、粒宽的遗传规律分析可以为其数量性状基因座定位、分子标记辅助选择育种和基因克隆奠定基础.调查大豆杂交组合溧水中子黄豆(P1)×南农493-1(P2)正反交的P1、P2、F1和F2:3四个世代的粒长和粒宽的表型资料,运用四个世代联合的主基因+多基因混合遗传分析方法,对这两个性状分别进行了遗传分析.结果表明:正反交杂种F1粒长和粒宽有显著差异,存在母性效应;粒长性状受一对加性-显性主基因和加性-显性.上位性多基因共同控制;粒宽受多基因空制.

| Abstract: | Seed length and width were related to soybean yield.The inheritance for the seed length and width may provide the foundation for mapping of quantitative trait loci(QTL),marker assisted selection and gene clone.In this article,P1and P2,F1 and F2:3 populations derived from the direct and reciprocal crosses between Lishuizhongzihuang and Nannong 493-1 were used to investigate the inheritance for the two traits mentioned above by using joint segregation analysis approach.The results showed that there were signi... |
