Two hundred and forty nine chickpea mutants in M4 generation developed through gamma irradiation and Ethyl methane sulphonate (EMS) were screened along with their respective parents and susceptible check Aug-424 for resistance to Fusarium wilt in natural wilt sick plot during 2003-2004 seasons. All the 4 parent genotypes showed highly susceptible reaction to Fusarium wilt. Out of a total of 249 morphological mutants of 4 genotypes, 75 mutants exhibited highly resistant reaction (less than 10 %) followed by 31 mutants resistant (11 to 20%), 34 mutants moderately resistant/ tolerant (21 to 30%), 35 mutants susceptible (31 to 50%) and 75 mutants were highly susceptible (50 to 100%). The mutagenic treatments proved to be effective in producing morphological mutations along with improved tolerance to Fusarium wilt. These mutants with resistant to tolerant reaction for Fusarium wilt could be used in hybridization program for transferring of resistance genes into high yielding elite cultivars/ producing better recombinants.
