Among the various plants breeding technique induced mutation using physical and chemical mutagens play a great achieving role in current days in improving economic value of the crop with genetic modification. In the present investigation foxtail millet [Setaria italica (L.) Beauv.] seeds were treated with different doses of gamma rays (GR) ranging from 200, 300 and 400Gy, varying concentration of ethyl methane sulphonate (EMS) 0.2, 0.3 and 0.4% and sodium azide (SA) 0.02, 0.03 and 0.04%. Variations in the germination percent of seeds, seedling height, seedling injury and survival of plant at maturity of foxtail millet were recorded in M1 generation. The effects of the mutagenic treatments on quantitative traits resulting in reduction in traits such as percent seed germination except 200Gy (86.13%), 0.2% EMS (85.96%) and 0.02% SA (87.21%), seedling height except 200Gy (7.02cm), 0.2%EMS (7.12cm) and 0.02%SA (6.96cm) while survival of plant at maturity except 200Gy (82.94%), 0.2% EMS (81.73%) and 0.02%SA (83.02%) but increases seedling injury except 200Gy (-02.03%), 0.2% EMS (-03.49%) and 0.02%SA (-01.16%) was observed in treated M1 generated plants.
