摘要
通过对二化性中、日系原种及其子代进行相关统计分析,初步获得如下结果:从遗传上结茧率与茧层量、茧层率为负相关,但不明显;在良好环境下的表型相关,日系品种的结茧率与茧层量、茧层率为负相关,中系品种则为正相关,但均不显著;唯有茧层量与茧层率之间无论遗传上还是表型上均表现密切正相关。
The relationship among cocooning rate and cocoon shell weight, cocoon layer ratio in bivoltine Chinese, Japanese strains and their filial generation. The results were as follows: (1) The negative relation among cocooning rate & cocoon shell weight & cocoon layer ratio were not significant on genetic character. (2) The relationships were negative in Japanese strains & positive in Chinese strains on phenotypic character in good breeding conditions. (3) The relation between cocoon shell weight and cocoon layer ratio were closely positive on both genetic & phenotypic character.
