Abstract
A total of 374 viable mutations were obtained from a very tall variety, Ingru Cholam, following treatments with gamma rays and/or methyl methane sulphonate (MMS) . There was a linear relationship between increasing mutagen dose and increasing frequency of viable mutations. Alternate treatments with gamma rays and MMS produced a higher number and wider range of mutations than those provided by each treatment alone. The mutations included variations in height, growth period, the size and shape of leaves and panicles, and seed fertility.
