| 摘 要： | 应用灰色系统理论分析方法,对18个家蚕纯种的万蚕产茧量和10个主要数量性状的相互关系进行了分析.结果表明,各个性状对万蚕产茧量的关联度由大到小的次序依次为:全茧量＞茧层量＞单蛾卵量＞四龄结茧率＞良卵率＞死笼率＞普茧率＞健蛹率=茧层率＞同宫茧率.可为家蚕纯种的定向培育和选育种提供参考.

| Abstract: | The relationship between cocoon yield/10 000 silkworms and ten main quantitative characters of ten silkworm varieties were analyzed by the grey related system theory.The results showed that the related degree between cocoon yield/10000 silkworms and ten main quantitative characters was cocoon weight>cocoon shell weight>egg weight per moth>cocoon rate at the fourth instar stage>good egg rate>rate of dead cocoons>normal cocoon rate>cocoon shell percentage>cocoon rate of the same,which can provide the referenc... |
