Abstract

An attempt was made to identify the superior cocoon parameter producing bivoltine silkworm hybrid from KSSR&DI, Thalaghttapura. 10 bivoltine silkworm hybrids were selected viz., HNPD, BBE266, NN6D, DD-1, KCR2, Viet 904, NK2, BRD12, SLX and SP4 their performance were analyzed for traits such as cocoon weight, shell weight and fibroin percentage and found the bivoltine hybrid HNPD was having superior cocoon weight (1.46g) and fibroin percentage (78.69%), whereas superior shell weight was found for the hybrid NN6D (0.272g) and least cocoon weight, shell weight and fibroin percentage was observed for the hybrid SP4, where they having 1.27 g, 0.240 g, and 76.99% of cocoon weight, shell weight and fibroin percentage respectively

Keywords

Silkworm, Bivoltine, Cocoon parameters, Fibroin

Conclusion

The result of the present study inferred that the bivoltine breed, HNPD registered highest cocoon weight and fibroin percentage and this character can be utilized during the development of silkworm breed
