摘要
本研究围绕长白猪选育目标,将典范分析与通径分析有机结合,实现了典范选择指数相关遗传进展的剖分,为构建和评价典范选择指数提供了一种有效方法.
Centre on breeding objectives, the Canonical Selection Index of Landrace Pigs is estimated by combination of canonical analytical and path analytical method. The total heredity progress CGSv(xi) of trait xi for Canonical objective trait (V) can be differentiated in parts : direct contributionCi of trait xi and indirect contribution rpijCj of trait xi via trait xj . It can help in the understanding of weight and function of each trait in Canonical selection index.
