近年来,育种研究中应用通径分析日趋增多,方法是利用性状间的遗传相关系数矩阵求出原因性状(x)与结果性状(y)间的直接遗传通径系数(p_(y·x)),它反映了原因性状基因型值对结果性状基因型值的直接作用。但由于选择是对表现型进行的,考虑到选择对于表型值的影响,采用相关遗传力的分析方法,就能将性状联系起来考虑,使基因型值
In recent years, path analysis has been increasingly used in breeding research by using the genetic correlation coefficient matrix between traits to find the direct genetic path coefficient (p_ (y · x)) between the causal (x) and the trait (y) ), Which reflects the direct effect of the trait genotype value on the trait genotype value. However, since selection is performed on phenotypes, considering the effect of selection on phenotypic values, using inheritance-based analysis methods, traits can be considered in relation to the genotype value
