Abstract:
The experiment was conducted to evaluate and identify suitable hybrids with comparatively improved economic traits specific for climatic conditions of Marathwada region of Maharashtra at Sericulture Research Unit, V.N.M.K.V, Parbhani, during 2021-22, laid in Randomized Block Design with six treatments and four replications. It is generally done in comparison with the existing commercially accepted popular variety and aimed to select the better strains than the existing ones. During the study (CSR₁₆ x CSR₁₇) x (CSR₅₀ x CSR₅₁) recorded significantly highest hatching percent (98.16 percent), 10 mature larval weight (43.75 g), single cocoon weight (2.12 g), shell weight (0.45 g), filament length (1205 m), filament weight (0.381 g) and cocoon yield (19.70 kg) was found significantly superior over rest of hybrids. CSR₅₀ x CSR₅₁ had shown shortest larval duration (22.10 days), maximum shell percentage (21.84 percent) and highest moth emergence (98.25 percent). Silkworm hybrid FC₂ x FC₁ showed lowest denier value (2.61) while (S₈ x CSR₁₆) recorded minimum pupal duration (10.00 days).
