Silkworm Breeding and Genetics Section, Central Sericultural Research & Training Institute, Berhampore, West Bengal 742101.
A study on genetic variability was made with 5 X 5 diallel of genetically divergent multivoltine lines to determine the importance of quantitative traits of mulberry silkworm, Bombyx mon L. Data were collected from rearings made during four commercial seasons of West Bengal. The study of phenotypic and genotypic variation, coefficient of variation, heritability and genetic advance for 10 quantitative traits indicated additive and nonadditive effects of genes which facilitates selection for the amelioration of breeds.
