利用综合优化方法，研究了在育种目标约束下，选择性状表现型向量与目标性状基因型向量的典范相关，提出了综合典范性状对的数学模型．综合典范性状对是S个间接近传系数较大的典范选择-目标性状对，在育种目标约束下间接遗传系数极大化的线性组合．综合典范选择性状．作为间接这择的指标，能较好地满足多目标育种的要求．
Using the comprehensive optimization method, we studied the canonical correlation between the selected trait vector and the target trait genotype vector under the breeding target constraint, and put forward the mathematical model of the comprehensive canonical trait pair. The comprehensive canonical pair is a linear combination of S, which has a large indirect proximization coefficient and a large number of target trait pairs, and indirect genetic coefficients under the breeding goal constraint. Comprehensive model selection traits. As an indirect indicator of choice, can better meet the requirements of multi-target breeding.
