Study was conducted for screening and evaluation of selected breed’s for nutrigenetic traits in silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) is an essential prerequisite for better understanding and development of nutritionally efficient breeds under Subtropical condition of North Western India based on the breeds which shows less food consumption with higher efficiency conversion. The aim of this study was to identify nutritionally efficient bivoltine silkworm breeds selected from different regions of our country. Highly significant differences were found among all nutrigenetic traits of bivoltine silkworm breeds in the study. The nutritionally efficient silkworm breeds were resulted by utilizing nutrition consumption index and efficiency for conversion of ingesta/cocoon traits as the index for selection of highly promising breeds. Higher nutritional efficiency conversions were found in the bivoltine silkworm breeds on efficiency of conversion of ingesta to cocoon and shell were shortlisted during spring season. Furthermore, based on the overall nutrigenetic traits utilized as index, eight bivoltine silkworm breeds (B.con 1, B.con 4, BHR 2, ATR 16, BHR 3, CSR 50, RSJ 14 and NB4D2) were identified as having the potential for nutrition efficiency conversion and can be utilized for further breeding programme. The data from the present study advances our knowledge for the development of nutritionally efficient silkworm breeds/hybrids and their effective commercial utilization in the sericulture industry.
