【摘要】 本文提出了研究相关遗传变异的一个新的遗传参数——相关遗传力,它定义为两性状的遗传协方差对两性状表现型标准差乘积之比,並证明表型相关系数等于相关遗传力和相关环境力之和。文中着重讨论了相关遗传力在间接选择和相关遗传变异分析等方面的应用,指出在这些方面用相关遗传力代替遗传相关系数,可以得到较简单且较满意的结果。最后用一个小麦方面的实例说明了这一遗传参数的应用方法和特点。更多还原

【Abstract】 Correlative heritability, a new genetic parameter about correlative geneticvariation, is proposed. It is shown that phenotypic correlation coefficient canbe partitioned into correlative heritability and correlative environmentabilityHow to use the correlative heritability in indirect selection and correlativegenetic anaysis is discussed. In these respects using correlative heritbilityinstead of genetic correlation can give simpler and better results. Finallythe aiticle explains the analysis method using this genetic parameter withwheat as an example.更多还原
