Abstract: Levels of genetic diversity in the silkworm populations affect with the yield of economic traits and its stability.Silkworm breeders across the country contributed significantly to the development of many bivoltine breeds not only with improved economic merit but also suitable for variable climatic conditions so as to make sericulture a sustainable avocation. The study was carried out to evaluate genetic potential of the ten silkwormgenotypes (CSR2, CSR4, SH6, NB4D2, PAM101, PAM111, PAM114, PAM115, PAM117 and CS6) for various traits during spring season (May-June) from2014 to 2018 at Central Sericultural Research and Training Institute, Central Silk Board, Pampore, Kashmir. On the basis of the evaluation index values ranking PAM117 (58.20), SH6 (53.46), PAM114 (52.03), PAM115 (51.88) and CSR2 (51.85) were identified as good performing genotypes for various economically important traits and are recommended for hybridization and other breeding programmes under temperate climatic conditions.
