Abstract:
The experiment was carried out to study the “Performance of Biological traits of single and double hybrids of silkworm (Bombyx mori L.) 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. Among the different hybrids reared, the bivoltine hybrid (CSR16 x CSR17) x DHP5 performed better for biological characters, larval duration (24.25 days) and effective rate of rearing (93.70 per cent) over rest of treatments and hybrid SHP5 x DHP5 performed better for hatching (91.53%) and pupal duration (9.53 days).
