摘要
本文提出了一种估计遗传力的方法即单元内混合家系相关法,并用这种方法及阈性状分析法进行了猪肢蹄结实度的遗传力估计,结果表明,对于多阈性状,用单元内混合家系相关法估计的结果准确性好。
In this paper, a method named Mixed-family Correlation within Units is proposed to estimate heritability. The results of the swine F-L soundness heritability estimates by this method and by Threshold Trait method are compared. It indicates that the Mixed-family Correlation within Units method is better than the Threshold Trait method when they are used to estimate heritability of multi-threshold traits.
