The studies on various multivoltine races viz., APDR-15, APM-3, L-14, Mcon-1, MH-1, Nistari and PM on mulberry S-30 variety carried out at Sericulture Laboratory, Navsari Agricultural University, Navsari during November, 2017- January, 2018. The results showed that APM-3 race found significantly superior in weight of mature larvae (21.25g/10 larvae), effective rate of rearing (87.32%), larval survivability (93.70%), single cocoon weight (0.94g), single shell weight (0.25g), shell ratio (27.73%), filament length (415.33m), filament weight (0.11g) and denier (2.43) with lowest larval duration (23.33 days), disease incidence (9.30%), renditta (8.66kg) followed by Mcon-1. Based on overall performance, the multivoltine race, APM-3 is the most suitable when reared on mulberry variety S-30.
