INDUCED VIABLE MUTATIONS IN Sorghum bicolor (L.) MOENCH WITH GAMMA RAYS AND METHYL METHANE SULPHONATE

Abstract

In a study of induced, mutagenesis in Sorghum, a total of 374 viable mutants has been isolated from both single and alternate treatments. A linear trend of increase in the frequency of viable mutations with increase in dosage of the mutagens was observed. A high frequency of viable mutants was obtained in alternate treatment than in single treatment. In alternate treatments the spectrum of viable mutants was wider, affecting various traits such as stature, duration, leaf, Panicle size and shape, seed. fertility than in single treatment.
