Abstract:

The present investigation was carried out at Central Sericultural Research and Training Institute, Pampore, Jammu & Kashmir (J&K) during spring, summer and autumn, 2017 to study the performance of eleven silkworm, Bombyx mori L, breeds (CSR2, CSR6, CSR27, CSR26, CSR50, PAM114, PAM117, APS4, APS5, SK6 and SK7) of different origin under temperate climatic conditions. The rearing was carried out under uniformed laboratory condition by adopting standard method. These eleven breeds were evaluated for their performance in eight metric traits viz., fecundity (No.), hatching (%), larval weight (g), yield per 10,000 larvae by number and by weight (kg), single cocoon weight (g), single shell weight (g) and shell ratio (%). The performance of breeds varied from season to season since they were originated from different progenitors. The data generated was analyzed statistically and subjected to multiple trait Evaluation index. On the basis of the evaluation index values ranking (Mano et al., 1993) CSR2, CSR6, CSR26, CSR27, CSR50, PAM114 and PAM117 were performed well in all the three seasons except CSR6 and CSR26 which didn’t performed well in summer and autumn whereas, APS4, APS5 and SK6, SK7 performed well in spring, summer and summer, autumn respectively. Based on their performance in all the three seasons, these parental breeds will be utilized for development of foundation crosses which will be further shortlisted for the development of bivoltine silkworm double hybrid suitable to temperate region of J&K as an alternate for ruling CSR double hybrid.
