Chickpea is grown under a wide range of climatic conditions and is known to be highly sensitive to salinity stress. An experiment was conducted during 2019-20 to study the morpho-physiological responses of chickpea (Cicer arietinum L.) genotypes to salinity stress, in the Department of Crop Physiology at College of Agriculture, Vijayapur. The present study was carried out with ten chickpea genotypes sown under three salinity concentration (0 dSm-1, 3 dSm-1 and 6 dSm-1). All the parameters were recorded at 30, 60 and 90 Days after sowing (DAS). The results indicated that, plant height, relative water content (RWC), SPAD value and membrane injury index were decreased with increase in salinity concentration from 3 dS/m to 6 dS/m. Maximum plant height was observed in 0 dSm-1 salt concentration for all genotypes. Among the genotypes significantly higher Relative Water Content (RWC) was recorded in JG11. While, lowest RWC was recorded in genotype ICCV96029 at 60 days after sowing. From the study it was observed that the genotypes JG 11, BGD 103, MNK 1 and ICC 1431 were tolerant to salinity while, ICCV 96029 and NBeG 47 were found to be salt sensitive genotypes.
