Abstract: Chickpea (Cicer arietinum L.) is the third most important pulse crop grown throughout the world. About 65 per cent of the global area and 68 per cent of global production of chickpea is contributed by India. Fusarium oxysporum f. sp. ciceri is a soil-borne as well as seed-borne fungus. During the past few decades, modern techniques such as mutation breeding by radiation and chemical mutagens have been tried to identification/creation of novel genes that impart disease resistance/tolerance in cultivars of many crop plants. Present investigation entitled “Radiation induced mutation for resistance against Fusarium oxysporum f. sp. ciceri (Cicer arietinum L.)” was aimed at identification of suitable mutant or a combination of mutants influencing resistance/tolerance to Fusarium wilt in chickpea. The experimental material was consisted of the population of four selected cultivars of chickpea (JG 62, BDNG 798, JAKI 9218 and Vijay) grown in randomized block design at College of Agriculture Golegaon, VNMKV, Parbhani during Rabi 2018-19. Among 11Mutagenic treatments seven treatments (20 KR, 30 KR, 0.2% EMS, 0.3% EMS, 20 KR+0.2% EMS, 30 KR+0.2% EMS) showed significant impact on various morphological and biological parameters of the plant habit. Efficacy of Gamma rays, EMS and their combination treatment screened for resistance/tolerance in M2 progeny mutant chickpea against two isolates of Fusarium oxysporum f. sp. ciceri by using root dip inoculation technique. Present finding revealed that combination treatment of 30 KR+0.2% EMS showed resistance/tolerance against both the isolates of Fusarium oxysporum f. sp. ciceri in the three experimental genotypes i.e., BDNG 798, JAKI 9218 and Vijay whereas, 0.3% EMS shows resistance/tolerance against both the isolate of Fusarium oxysporum f. sp. ciceri for Vijay genotype.
