Genetic improvement through induced mutation has been very effective in improvement of crops. Seeds of three popular chickpea variety namely BGM 408, B115 and JG 315 were treated with 10, 20 and 30 kR of gamma rays. Then treated seedswith their respective control(0 kR gamma rays) weresown in the field of Calcutta University experimental farm, Baruipur (with no salinity) in three consecutive years to raise M1, M2 and M3 generations respectively. Some M3 lines having higher yield potential were subjected to grow as M4 lines in salt stressed field (5-7ds m-1) of Hingalganj, South 24 Parganas. Finally, some promising salt tolerant lines with improved seed yield were selected which have a good promise for coastal saline belt after releasing as a variety.
