利用Ｈａｙｍａｎ双列分析法对不同磷营养效率品种所组配的杂交组合方差和协方差回归分析表明，磷效率相关性状遗传符合加—显性模型，有的性状还存在非等位基因间互作，大部分性状有较高的广义遗传力和较低的狭义遗传力；亲本特殊配合力基因型方差比一般配合力基因型方差大，在群体性状的遗传上特殊配合力更重要 Analysis of variance and covariance regression analysis of hybrid combinations with different phosphorus efficiency cultivars by Hayman’s double-row analysis showed that the inheritance of phosphorus-related traits conforms to additive-dominance model, and some traits also exist non-allelic interactions , Most of the traits had higher general heritability and lower heritability. The variance of genotypes with special combining ability of parents was greater than that of general combining ability genotypes, and the heritability of group traits was more important
