| 摘 要： | 本文通过45个谷子品种,计算了谷子的相关遗传力,探讨了谷子的定向选择,这在谷子遗传育种中报道还不多见。相关遗传力是单个性状的遗传力在两个相关性状上的推广,可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。因为表型相关系数等于相关遗传力和相关环境力之和,若用相关遗传力代替表型相关系数对相关性状进行选择,可以得到较满意的结果。

| Abstract: | Correlative heritability,a new genetic parameter about correlative genetic varation was proposed. It was shown that phenotypic correlation coefficient could be partitoned into correlative heritability and correlative environmentability. How to use the correlative hertability in indirct selection and correlative genetic analysis was discussed. Using correlative heritability can give better and simpler results that using genetic correlation. |
