The first, second and third instar silkworm Bombyx mori were reared on MI-79, ME-52, S-36, S-13 and C-20. The larvae fed on MI-79 recorded higher growth rate (0.68), (0.78) and (0.82) at first, second and third instar respectively followed by S-36 and least growth rate found in C-20(0.57) and (0.64) at first and second instar respectively. Significantly minimum growth rate was recorded when silkworms were reared on ME-52 (0.76) at third instar. The variation of growth rate among mulberry accessions might be due to difference in biochemical constituents present in the mulberry varieties.
