摘　　要：本文根据数学规划的原理和方法，提出了优化杂交方案的评定模型，并就复合配合力的构造方法及其性质作了进一步探讨。实际应用的结果表明，所建模型在资源有限的情况下，可以获得能够创造最大产值的杂交方案，且给出方案中不同杂交方式的优化结构；由特征值与特征向量所建立的复合配合力，不仅可以对杂交亲本进行综合评定，且可进行不同方向性选择，以筛选出在杂交体系中担任不同角色的适宜亲本。Based on mathematical programming theory and method,an evaluation model of optimum crossbreeding programm is presented and the character and constructing method of the compound combining ability are discussed.The applied results showed that the optimum crossbreeding programm under a given condition and the optimum structure of the mode of different crossbreeding in this paper were applied to the evaluation of crossbreeding programm and to the selection of crossbreeding mode.The compound combining ability constructed by eigenvalue and eigenvector able to be applied to the multiple evaluation on crossbreeding parents and to the direction selection of those as well.
