The experiment was conducted at Sericulture Research Unit, V.N.M.K.V, Parbhani, during 2016, in randomized block design with nine treatments and three replications. The variety V-1 was utilized. The bivoltine hybrids viz., CSR₂ × CSR₄, CSR₂ × CSR₅, CSR₁₆ × CSR₁₇, CSR₅₀ × CSR₅₁, CSR₃ × CSR₆, CSR₁₂ × CSR₆, CSR₁₈ × CSR₁₉, (CSR₅₀ × CSR₅₂) × (CSR₅₁ × CSR₅₃) and (CSR₂ × CSR₂₇) × (CSR₆ × CSR₂₆) was utilized as treatment. Among the different hybrids reared, the bivoltine double hybrid (CSR₂ × CSR₂₇) × (CSR₆ × CSR₂₆) performed better for economic characters viz., hatching per cent (93.27 per cent), larval duration (22.68 days), weight of ten mature larvae (44.04 g), single cocoon weight (1.82 g), shell weight (0.388 g), shell ratio (21.34 per cent), filament length (999.33 m), filament weight (0.308 g), cocoon yield/10000 larvae brushed (18.84 kg) and low disease incidence (3.51 per cent) over rest of treatments.
