Abstract

Salinity stress is a non-toxic and important limiting factor for crop production. Due to the increasing salinity of the country, identification of salinity tolerant genotypes in crops such as chickpea is important in areas where salinity is high. This experiment was carried out in a greenhouse of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardebili, in a randomized complete block design with three replications. First factor: 19 chickpea genotypes and the second factor was salinity stress 3 levels (control, 0.05 and 0.1 mM sodium chloride). The results of this study showed that salinity levels reduced the chlorophyll index in chickpea. Among the genotypes, the highest chlorophyll index was obtained in Genotype 1 and the lowest was observed in Genotype 19. In interaction of salinity and chickpea genotypes, genotype 11 had the highest chlorophyll index. Also, the lowest chlorophyll index in chickpea was in genotypes 17 and 19. The results of this study showed that genotype 1 is susceptible to cultivation in high salinity areas among genotypes.
