다국어 초록 (Multilingual Abstract)

Since the estimate of the genetic relations between characters gave us effective basic informations about the selection of good strains of silkworm, the experiment was carried out to estimate the heritability and the genotypic correlation, etc. using the 21 combinations F1's by diallel crosses of seven strains of the silkworm.
As the result of this experiment some conclusions obtained were as follows;
1. The genotypic correlation is estimated highly positive in the heritability for all the 9 chcracters.
2. The correlations between all the characters are positive and the genotypic correlation is generally higher than the phenotypic one.
3. Since all the correlations between the bave length and other characters are highly positive, it can be considered that the effects of the other characters on the bave length are very important.
