本文提出了一种用纯合基因型估计数量性状遗传力的新方法。该法的试验不需设置重复,只要有若干纯合基因型在两种不同环境(如年份、地点或栽培措施)下的观测值即可,因此特别适合于作物品种资源研究或育种实践中的资料分析。文中用一个油菜实例对本法和现有唯一的用纯合基因型估计遗传力的方差分析法进行了比较,结果表明本法具有试验简单,计算容易和估值更为实际等优点。
This paper presents a new method to estimate the heritability of quantitative traits using homozygous genotypes. The test of this Act need not be repeated, as long as there are several observed values of homozygous genotypes in two different environments (eg year, place or cultivation measure) and are therefore particularly suitable for crop variety resource research or breeding practice ANALYSE information. In this paper, an example of rape is used to compare the present method with the only existing ANOVA which estimates heritability using homozygous genotypes. The results show that this method has the advantages of simple experiment, easy calculation and more realistic valuation.
