Abstract
The present investigation
was undertaken to evaluate and compare the commercial cocoon and silk quality
traits of two reciprocal bivoltine silkworm hybrids of Bombyx mori,
namely PM×CSR2 and CSR2×PM. A comprehensive assessment of key economic
parameters including cocoon weight, shell weight, shell ratio, filament length,
denier, raw silk percentage, and renditta was carried out under uniform rearing
and environmental conditions by following the standard evaluation procedures
outlined by Benchamin and Nagaraj (1987). The results revealed distinct and
consistent differences between the reciprocal hybrids, clearly demonstrating
the presence of reciprocal effects on important commercial traits. These
variations can be attributed to maternal inheritance and cytoplasmic influences
affecting growth and silk production, which is in agreement with earlier
findings reported by Datta (2000) [3] and Ramesha et al.
(2010) [8].
