dc.description.abstractThe present investigation was undertaken to screen the chickpea genotypes for the growth behavior and alteration in yield contributing traits during salinity stress. Twenty two diverse chickpea genotypes were evaluated for salinity tolerance. The experiment was conducted in plastic pots raised under rain out shelter. The treatments comprised of control, 20mM and 30mM NaCl applied in split doses: 50% at the time of sowing and remaining at 15 days after sowing. The observations on various physiological and biochemical traits were recorded at 65 DAS (vegetative stage), 90 DAS (flower initiation) and 110 DAS (pod initiation) and yield attributes at maturity. Salt stress profoundly affected the growth attributes. All the genotypes depicted reduction in plant height, leaf area and biomass efficiency. The photosynthetic pigments, activity of nitrate reductase and relative leaf water content was also reduced in response to salt application with effect being more pronounced in identified salt sensitive genotypes (ICC15868 and GL26054) as compared to salt tolerant ones (BG1053, L550, ICC8950 and ICCV10). Lipid peroxidation increased with both the salinity levels. Under saline conditions higher accumulation of osmotic solute proline, total proteins and protein fractions was observed with tolerant genotypes in contrast to sensitive genotypes. Salt imposed stress finally caused a higher decline in yield attributes of sensitive genotypes as compared to tolerant. The genotypes viz. BG 1053, L550, ICC8950 and ICCV10 were identified as salt tolerant.en_US
