TL;DR: Some promising salt tolerant lines with improved seed yield were selected which have a good promise for coastal saline belt after releasing as a variety.
Abstract: Genetic improvement through induced mutation has been very effective in improvement of crops. Seeds of three popular chickpea variety namely BGM 408, B115 and JG 315 were treated with 10,20 and 30 kR of gamma rays. Then treated seeds with their respective control(0 kR gamma rays) were sown in the field of Calcutta University experimental farm,Baruipur (with no salinity) in three consecutive years to raise M1, M2 and M3 generations respectively.Some M3 lines having higher yield potential were subjected to grow as M4 lines in salt stressed field (5-7ds m-1) of Hingalganj,South 24 Parganas. Finally, some promising salt tolerant lines with improved seed yield were selected which have a good promise for coastal saline belt after releasing as a variety.

TL;DR: Chickpea varieties (BG-256 and CSG-8962) were subjected to salt stress (50mM, 100mM and 150mM of NaCl) in a pot experiment as discussed by the authors.
Abstract: Chickpea varieties (BG-256 and CSG-8962) were subjected to salt stress (50mM, 100mM and 150mM of NaCl) in a pot experiment. Untreated plants served as control. Plants were analyzed from 20 DAS up to 60 DAS at ten-day interval. Salt stress significantly reduced growth parameters like biomass, net assimilation rate, relative water content and biochemical parameters viz., total nitrogen and protein content of both the varieties. However, decrement was more pronounced in sensitive (BG-256) than in tolerant (CSG-8962) variety. Proline content increased with increase in salt exposure in both the varieties. SDS-PAGE of the protein reveal large amount of protein degradation in plants treated with high concentration of salt.
