The process of removal of gummy proteinous material sericin from silk is commonly called as degumming loss or boil-off loss ratio. In the present study, the boiloff loss ratio in the cocoon shells of twelve multivoltine × bivoltine hybrids and their parents were analysed. Inheritance pattern of boil-off loss ratio was analysed in crosses involving high and low boil-off loss parents, F1s, F2s and back-crosses by parent off spring regression analysis. Heterosis and heterobeltiosis was also analysed for this character. Highly significant (P > 0.01) variations were observed in eight out of ten multivoltine and two out of five bivoltine parents indicating the presence of genetic variation in the expression of boil-off loss ratio. Among F1 hybrids, ten hybrids expressed significant (P > 0.01) variations when compared with control hybrid PM × NB4D2. Significant negative heterosis was expressed in three multi × bi hybrids viz., BL67 × CSR101, 96A × CSR19 and 96C × CSR19, which is desirable for this character, whereas expression of heterobeltiosis was significant only with one hybrid, 96C × CSR18 in desired direction. Studies on inheritance pattern showed that the character is heritable and contribution percentage of female and male in the ratio of 50.9: 49.1 and it appears that both the parents are influencing in the expression of boil-off loss ratio in silkworm. Based on the overall performance and evaluation by multiple trait evaluation index and also considering the expression of the boiloff loss ratio three hybrids viz., BL67 × CSR101, 96A × CSR19 and 96C × CSR18 were found superior and recommended for commercial exploitation.
