生物的遗传性状(表现型)是受基因控制和环境影响的。对某一性状的遗传规律进行研究,可以了解其遗传变异和环境条件影响的相互关系,预测其杂交后代的性状表现,从而提高育种工作的效率。不同的家蚕品种的叶丝转化率的遗传性状如何,饲料效率有无显著性的差异,这对在家蚕选育过程中的早期世代进行预测能否选育出叶丝转化率高的品种,是一个极其重要的问题。
Biological genetic traits (phenotypes) are controlled by genes and the environment. Studying the genetic law of a trait can understand the relationship between the genetic variation and the environmental conditions and predict the trait performance of the hybrid offspring so as to improve the efficiency of breeding. The silkworm varieties of different silkworm conversion rate of genetic traits, feed efficiency, there is no significant difference, which in silkworm breeding process of early generation can predict the breeding of silkworm varieties with high conversion rate, is An extremely important issue.
