摘要
根据生统遗传学基本原理，提出谷类作物种子性状双列资料［包括ｐ２和ｐ（ｐ＋１）／２双列与ｐ＋ｑ＋２ｐｑ和ｐ＋ｑ＋ｐｑ不完全双列］遗传分析的新方法。各种资料都可以测验和估计加性方差σ２ｄ，显性方差σ２ｈ，误差方差σ２ｅ，平均加性效应［ｄ］，平均显性效应［ｈ］以及性状的遗传控制系统（即受母体或胚乳基因型控制）。ｐ２和ｐ＋ｑ＋２ｐｑ双列还能测验和估计细胞质效应ｃ和方差σ２ｃ；ｐ＋ｑ＋２ｐｑ和ｐ＋ｑ＋ｐｑ双列又可测验和估计两组亲本的遗传背景差异［ｍ］。
A new method was proposed for genetic analysis of seed traits in cereal crops, which may be applied to p 2 and p(p+1) /2 diallel data and p+q+2pq and p+q+pq incomplete diallel data. The genetic control of the seed trait under consideration, (i.e., subject to the maternity or endosperm/embryo genotypes), as well as additive variance σ 2 d , dominant variance σ 2 h , error variance σ 2 e , average additive effect and average dominance effect can be tested and estimated statistically for all of the above diallels. And the cytoplasmic effect c , variance σ 2 c and the background difference between two groups of pure parents , , can yet be added for p 2 and p+q+2pq diallels, and p+q+2pq and p+q+pq diallels, respectively. A worked example about gum content in barley seeds was given for demonstration.
