Mutagenic effect of gamma rays, chemical mutagens, and combined treatments in sorghum

K. Sree Ramulu

Abstract

Sorghum subglabrescens seeds were treated with gamma rays, ethyl methanesulphonate (EMS), methyl methanesulphonate (MMS) and diethyl sulphate (DES) separately or in various combinations of gamma rays + chemical mutagen. The combined treatments were not additive in respect of M1 effects, but the frequency of chlorophyll mutations in the M2 showed additive effects for gamma rays + EMS and less than additive effects for the other combined treatments. Mutagenic efficiency, estimated on the basis of seed sterility, was more than additive for gamma rays + EMS
