Abstract

The studies on nine different multivoltine races viz., Pure Mysore, Hosa Mysore, Mysore Princes, Kolar Gold, C. Nichi, G Race, P2D1, CB5 and Nistari on M-5 variety of mulberry larval duration, weight of ten matured larvae, diseases mortality (%), single cocoon weight, denier and fecundity were undertaken during 2012-13. The studies shows that Kolar Gold race was recorded superior for weight of the ten mature larvae (22.16 g), Pure Mysore was recorded significantly superior for incidence of disease (1.50%) and fecundity (508.61 eggs). The race P2D1found superior for single cocoon weight (0.980g) and cocoon yield (9.800 kg). The race C.Nichi was recorded superior for denier (1.68) and larval duration (22.96). Hosa Mysore race (16.10%) was found significantly superior over rest of the races for shell ratio.
