Abstract:
The experiment was carried out to study the “Performance of single and double hybrids of silkworm (Bombyx mori L.) for economic traits on Mulberry” at Sericulture Research Unit, Department of Agricultural Entomology, College of Agriculture, VNMKV, Parbhani during 2020 – 2021. The variety V-1 was utilized during experiment. The hybrids viz., BL67 x CSR5, SHP5 x DHP5, DHP5 x SHP5, (CSR16 x CSR17) x DHP5, (CSR2 x CSR40) x (S8 x CSR16), (CSR46 x CSR47) x (S8 x CSR16), (S8 x CSR16) x (CSR50 x CSR51) and (CSR2 x CSR4) x (G3 x G2) were utilized as treatments. The weight of cocoons was found to be in the range of 1.54 g to 1.92 g. The significantly highest cocoon weight was observed in (CSR16 x CSR17) x DHP5(1.92 g) over the rest of the hybrids, The maximum shell weight was recorded by the bivoltine hybrid (CSR16 x CSR17) x DHP5 (0.403 g). Among double hybrids, the two double hybrids (CSR46 x CSR47) x (S8 x CSR16) (0.367 g) and (S8 x CSR16) x (CSR50 x CSR51) (0.363 g) shown superior performance over the control treatment (CSR2 x CSR4) x (G3 x G2) (0.356 g). The bivoltine hybrid (CSR16 x CSR17) x DHP5 recorded highest filament length (1140 m) followed by the hybrid (CSR2 x CSR4) x (S8 x CSR16) (1096 m). Only two hybrids (S8 x CSR16) x (CSR50 x CSR51) (783.33 m) andBL67 x CSR5 (793.33 m) shown non-significant filament length values to control treatment (CSR2 x CSR4) x (G3 x G2) (840 m) and The filament weight was varied from 0.294 to 0.322 g and the highest filament weight of T4 hybrid (CSR16 x CSR17) x DHP5 (0.322 g). The significantly lowest filament weight was observed inBL67 x CSR5 (0.294 g) and (S8 x CSR16) x (CSR50 x CSR51) (0.298 g).
