ABSTRACT

Three breeding plans were initiated using three bivoltine commercial hybrids from China with
an objective to inbreed productive bivoltine pure lines. A total of 09 inbred lines including two sexlimited larval marking, one each of oval and dumbbell, two plain oval, three plain dumbbell and two marked dumbbell lines were developed. Evaluation and characterisation of all these lines was detailed in the investigation. The lines showed productive merit for pupation rate, cocoon weight, single shell weight, cocoon shell ratio, filament length and reelability besides exhibiting tolerance/resistance to BmIFV, BmDNV and BmNPV.
