The relative effects of some chemical mutogens vir mytomycin-c and E.M.S. in different concentrations at egg and pupal levels of taser producing insect. Antheraea mylitta-D in relation to its economic characters have been evaluated during the red crop and commercial crop season. Results of the experiments are indicative of the fact that lower concentration of chemical mutagens having 0.01% and 0.1% as effective in improving the cocoon weight shall weight shall ratio filament length. And denier of tasar yarn. The higher concentration of E.M.S. and mytomycin-c have shown lethal effect and adverse manifestation on the Economic characters of tasar. No seasonal variation in respect of two different seasons have been noticed. The results obtained may be due to stimulating effect of mutagens on the life cycle of tasar silk worm. Which is very much in conformities with the earlier work carried out by Sharma and Kumar.

Antheraea mylitta-D mytomycin-c E.M.S. seed crop. Commercial crops.
