Abstract
An experiment was conducted to evaluate the performance of bivoltine mulberry silkworm (Bombyx mori L.) hybrids under Marathwada conditions at Sericulture Research Unit, Marathwada Agricultural University, Parbhani during October-November, 2008. The bi x bi hybrid CSR16 x CSR17 was found significantly superior with hatching percentage of 95.22. Maximum larval weight (45.08 g), maximum single cocoon weight (1.98 g), single shell weight (0.393 g), filament length (950 m), cocoon yield/10000 larvae brushed (18.55 kg), effective rate of rearing (96.33 per cent), whereas significantly superiority in less larval duration and shelling percentage was found in bi x bi hybrid CSR 18 x CSR 19 (22.65 days) and CSR 48 x CSR 4 (20.98 per cent), respectively. The multi x bi hybrid PM x CSR2 recorded significantly less disease incidence. Based on overall performance it can be concluded that the bivoltine hybrid CSR16 x CSR17 reared on mulberry variety V-1 was the most suitable and economical for rearing under Marathwada conditions
