| 摘 要： | 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个间撞遗传系数较在的典范选择－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，作为间接选择的指标，有较好地满足多目标育种的要求。

| Abstract: | This paper studies the relation between the selective characters' phenotypic vector and objective's genotypic vector under the restriction of breeding objectives and it also sets up the model of comprehensive canonical trait pair by using integreted and optimized methods CCT is a linear combination of S CTPs which has larger indirect hereditary coefficient (IHC) and a maximal IHC under the restriction of breeding objectives. As an indirect selection index,compreherrisive canonical trait can satisfy the needs of multi-objective breeding faily good. |
