Abstract
The experiment was conducted at Sericulture Research Unit, V.N.M.K.V, Parbhani, during 2022, in randomized block design with six treatments and three replications. The variety V-1 was utilized during experiment. The hybrids viz., (CSR16 x CSR17) x (CSR50 x CSR51), FC1 x FC2, FC2 x FC1, S8 x CSR16, CSR50 x CSR51, and CSR16 x CSR17 were utilized as treatments.
Among the different hybrids reared, the bivoltine hybrid (CSR16 x CSR17) x (CSR50 x CSR51) and FC1 x FC2 were performed better for economic characters viz., hatching per cent (98.16 per cent), weight of ten matured larvae (43.75 g), single cocoon weight (2.12 g), single shell weight (0.45 g), filament length (1205 m), filament weight (0.381 g) and cocoon yield/10,000 larvae brushed (19.70 kg). Hybrid CSR50 x CSR51 recorded larval duration (22.10 days) and shell ratio (21.84 per cent), FC2 x FC1 recorded lowest denier (2.61). The mulberry green tea powder per 100 g. recorded moisture 9.59 g., ash 12.59 g., Fat 3.68 g., Protein 14.87 g., Fibre 18.50 g., carbohydrates 40.77 g. and Energy 255 Keal. Silkworm litter recorded nitrogen 2.08 per cent, phosphorus 0.74 per cent, potash 1.60 per cent, calcium 1.54 ppm, magnesium 0.65 ppm and sulphur 0.27 ppm, respectively.
