The effects of gamma rays and EMS on plant regeneration and somaclonal variation in fingermillet were studied. While EMS had an inhibitory effect on plant regeneration, gamma irradiation in low doses (5 Gy) was stimulatory. A wide range of variation was observed for almost all the traits and it was similar in both mutagen treated and untreated regenerants and seeds. This indicates that tissue culture itself induces variation and it can be exploited to advantage for crop improvement.
