摘 要：
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.
