Abstract

Salinity is a major environmental problem in arid and semi-arid areas. Chickpea (Cicer arietinum L.), like other legumes is sensitive to salinity. Therefore, selection of genotypes to grow on saline areas is important. This experiment was conducted in research greenhouse of the Faculty of Agriculture, University of Mohaghegh Ardabili in 2019 and a factorial experiment based on randomized complete block design with three replications. Experimental factors were first factor: 19 chickpea genotypes and factor two include salinity at three levels (0 as control, 0.05 and 0.1 mM) as NaCl. The results showed that with increasing salinity, chickpea height decreased. Among genotypes of chickpea, the highest plant height was observed in genotype 6, genotypes 1, 2, 3, and 5 were in the same group as treatment 6, the lowest plant height was obtained in genotypes 18 and 19. In salinity of 0.1 mM, the highest chickpea height was obtained in genotypes 2 and 3 and the lowest chickpea height was observed in genotype 15. This experiment showed that genotypes 1, 2, 3, and 6 can be recommended in areas where there is a problem with salinity.
