Genetic improvement for higher production and better quality considered pivotal to agriculture. Improvement in either single or few economic traits and quality characters can be achieved with the help of induced mutations within the shortest possible time. The study was conducted to study 28 mutants of the chickpea cultivar Gab4 in the third generation M3. Seeds of the M3 generation together with the untreated control were evaluated in a randomized block design with three replications at the Agricultural Science Research Center in Lattakia, Syria during winter 2020. Observations were recorded for days to 50% flowering, plant height,number of pods per plant, number of seeds per plant, 100 seed weight and seed yield per plant. The highest number of high-yield mutant strains resulted from treatment with 15KR of gamma irradiation. The highest seed yield was recorded in the mutant strain 15-16 (49.37 g.plant -1). The results indicated that the dose of 20KR of gamma irradiation was the most effective in decreasing seed weight, while the dose of 15KR was the most effective in increasing the number of pods per plant, number of seeds per plant, and seed yield per plant in the mutants. In contrast, the dose 25KR of gamma irradiation was the least effective among all doses.
