There is a dearth of bivoltine silkworm hybrids specific for seasons and regions. In this line APSSRDI has made an attempt in identification of silkworm hybrids for high temperature and high humidity tolerance. The experiment all the silkworm genetic stocks with high productivity and temperature tolerance were selected for screening the initial parents. These stocks were exposed to high temperature (36 °C) and high humidity (85-90%) for identification of resource material. Among the breeds ten promising stocks, five each of oval and peanut have been selected as breeding resource material on the basis of their tolerance to high temperature and high humidity. By utilizing these breeds, 100 combinations were prepared by following complete diallel method and evaluated. Accordingly 28 hybrid combinations were short listed for targeted traits and in subsequent trials, most promising single hybrid, APC1 x APJ1 was identified for further studies.
