【摘要】 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更多还原

【Abstract】 Genetic properties of characters related to the phosphorus efficiency were sutdied by diallel cross design Ⅱ and analyzed by Hayman diallel analysis method.Inheritance of characters related to the phosphorus efficiency were additive-dominance genetic effect and some of observed characters were of non allele effect.High estimates of heritability were obtained in most of the observed traits.The specific combining ability was more important than general combining ability in population inheritance because the variance of specific combining ability were bigger than that of general combining ability.更多还原
