With 4 bivoltine strainsas group A and 4 strains of bivoltinism, with their ancestry of multivoltinism, or of multi-voltinism as group B, 32 crosses were made according to a diallel mating design to evaluate the combining ability and heritability of resistance of silkworm larvae to CPV. The result showed that the relative effect values of the general combining ability (GCA) among parents and the special combining ability (SCA) among crosses were significantly different. The differences of the relative effects of the GCA among multivoltine strains and bivoltine strains containing multivoltine pedigrees were larger than those among bivoltine strains. The reciprocal crosses as well as the crosses of one of these strains outcrossed with other stra ins gave different values in the relative effect of SCA of the same strains. Moreover, diallel analysis showed that the variance of GCA(Vg% ) was 76.63%, the value of SCA (Vs% ) was 23.37. In the reciprocal crosses the variance for GCA ( Vg% ) was 45.12, and the variance for SCA (Vs%) was 54. 88. Therefore, the former showed an obvious additve effect and the latter gave a non-additive effect. The broad sense heritability ( BSH ) was 87.84% and the narrow sense of heritability ( NSH ) was 67.32%. But in the reciprocal crosses, BSH was 97.06%, NSH was 43.79%.

The main results are as follows: Variances of general combiningability (GCA) of 10 quantitative characters among each strain tested, as wellas those of special combining ability(SCA) of 9 characters among crosses wereall highly significant. The relative effect values of different characters in eachstrain were significant, so were those for different strains of each character.The ranges in GCA of characters among strains were different. It was foundthat each cross had different relative effects in different characters, and eachcharacters in different strains also had different relative effect values. TheSCA of different crosses showed a complex manner, however, it was possibleto evaluate the SCA of F1 crosses according to their parent's GCA. The cocoon shell weight. The cocoon shell percentage. the cocoon filamentlength, the number of eggs produced by one female had higher narrow senseof heritability (NSH), while the cocoon weight. the reelability. the length ofnon--broken cocoon filament. the cocoon filameut size, and the sensitivity toNPV had middle or lowor NSH. Moreover, The BSH of some characters weremuch higher than their NSH, it indicated that the nonadditive effects werestill significant.
