Review Paper on Successive Doses of Gamma Irradiation and EMS for Inducing Mutation in Glycine max and Brassica juncea.

Abstract

Suitable dose of mutagen in mutational breeding play a key role in developing a new mutant. Every plant’s seed have different number of chromosome, time duration of S phase, and morphology of seed like size of seed, seed coat and biochemical composition of seed. On the basis of these characters different type of seeds require different wavelength of gamma rays and different concentration of EMS for inducing mutation in mutational breeding. The present work on successive dose of Gamma irradiation and EMS for Glycine max (Soybean) and Brassica juncea (Indian mustard) helps to select correct doses of mutagen for the suitable crop.
