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