Study of economic traits of different silkworm hybrids on V-1 cultivar of Morus alba

The present investigation was conducted to study the economical traits of bivoltine silkworm hybrids on V-1 mulberry variety at Sericulture laboratory, Department of Entomology, Post Graduate Institute, Dr. P.D.K.V. Akola during 2023-2024, laid in Completely Randomized Design with seven treatments and three replications. During study, it was observed that among all the hybrids used for rearing, FC2×FC1 found the significantly superior over the rest of other hybrids tested in case of highest weight of ten mature larvae (40.20gm), single cocoon weight (1.89 gm), single shell weight (0.38 gm), shell ratio (20.32%), which was found statistically at par with hybrid S8 X CSR16. However, these two hybrids were found significantly superior over rest of hybrids tested. In case of filament length and filament weight hybrid FC2×FC1 has shown superior performance followed by hybrid TT21 X TT56, which was statistically at par with each other
