Abstract
The two varieties of cocoons viz., multi-bivoltine crossbreed cocoons (PM × NB4D2 race) and bivoltine hybrid cocoons (CSR2 × CSR4 race) reared during the sarne season were studied for the reeling performance and quality characteristics. The results indicate that the cocoon races have significant influence on the cocoon characteristics viz. Cocoon weight, shell weight, shell ratio percentage, average filament length, non-breakable filarnent length, single cocoon filament denier, on the reeling characteristics, viz. reelability, renditta, raw silk percentage, raw silk recovery percentage, waste generated during reeling and pelade weight and on quality characteristics, viz. neatness, cleanness, tenacity, elongation, cohesion, degumming loss characteristics of raw silk.
