Evaluation of Bivoltine Hybrids of the silkworm, Bombyx Mori L.

In India, bulk of silk produced is from multivoltines which are of inferior quality. It is a fact that more than 96% of the silk produced comes from multivoltine x multivoltine or multivoltine x bivoltine hybrids. Quality silk can be produced only from bivoltines. Therefore, it is highly pertinent to have more bivoltine silkworm breeds known for quality silk. However, the hot climatic conditions of India is not conducive to rear bivoltine hybrids. Hence, there is an urgent need to develop bivoltine hybrids which can yield stable crops under adverse climatic conditions. Keeping this in view, an attempt has been made to evaluate the bivoltine hybrids under high temperature and high humidity conditions.
