HYBRID VIGOUR IN THREE-WAY CROSSES OF MULBERRY SILKWORM BOMBYX MORl L.
Main Article Content
Abstract
The present experiment was carried out with a view to combine the best characters of the popular evolved multivoltine breed 'G' with bivoltine hybrids for rearing under tropical conditions. The crosses and their parents were reared during three seasons for study of heterosis. Heterosis over mid-and better parents was determined for seven important commercial characters. The degree of heterosis varied considerably for different economic characters in different seasons. Highly significant he.terosis was noticed over both parental values for most of the characters during dry summer season. The overall data indicate that two crosses viz., G x (PSxNB18) and G x (NB18xP%) during dry summer and two crosses viz., G x (KPG-BxNB7) and G x (NB7x KPG-B) during autumn and winter seasons can be exploited commercially in the tropical plants.
