Abstract
The present investigation was conducted to know the economic traits of silkworm Bombyx mori L. two multivoltine races C. niche and Pure Mysore and two bivoltines NB4D2 and CSR2 were utilized to prepare four hybrids – viz., PM x NB4D2 and PM x CSR2, NB4D2 x PM and CSR2 x PM were analyzed for eleven economic characters namely fecundity, hatching percentage, larval duration, larval weight, cocoon weight, shell weight, shell percentage, length of the filament, pupation rate, denier and renditta in monsoon season. The results revealed that in multivoltine the pure Mysore recorded better performance in economic characters except Length of filament and denier than C.Nichi. The bivoltine CSR2 showed better in all economic character than NB4D2. Accordingly, cross from the pure race/ breeds ie., hybrids NB4D2 x PM recorded better in the more in fecundity, hatching percentage, larval weight, cocoon weight, shell weight, shell percentage, pupation rate and denier. CSR2 x PM has lower larval duration with higher renditta compared to all hybrids.
