| 摘 要： | 对蚕种繁育中个体选择的标准和方法作了探讨，提出以被选个体偏离总体重心的概率大小即马氏距离作为个体选留淘汰的综合指标。该方法在综合考虑品种特性（全茧量、茧层量和茧层率）方面，比现行个体选择标准（限值淘汰方法）更为合理。

| Abstract: | In this article,standards and methods for individual selection in reproducingparental stocks of silkworm,Bombyx mori are discussed.It is suggested that the devia-tion probability of the individuals,i.e,the Mahalanobis'generalized distance,is agood comprehensive index for the selection,It includes the comprehensive characters ofthe variety(single cocoon weight,cocoon shell weight and shell percentage).It is morereasonable than the current method (critical value elimination method). |
