| 摘 要： | 考虑育种目标的要求，对多个独立的主成分性状进行综合优化，建立了综合主成分性状的数学模型．综合主成分性状是S个表型方差（遗传方差）最大的主成分性状在育种目标约束下表型方差（或遗传方差）极大化下的线性组合，作为育种指标，选择效果好，预见性强．

| Abstract: | Comprehensive principal component trait is set up by restriction of breeding objective using integration and optimization methods. It is a linear combination of s traits with principal component which have larger phenotype or genotype variance. As selection index, ti is unique, predictable and can result in good selection effect. |
