Thirteen salt tolerant wheat genotypes along with a local cultivar, WQS 160, were investigated for their response to five levels of irrigation water salinity viz. Control (2 dSm-1), 4, 8, 12 and 16 dSm-1 consecutively during two winter seasons. The results indicated that the effects of year, salinity, genotypes and their interactions were highly significant with respect to K+, CI-, K+/Na+ ratio and protein. All the ANOVA components except three factor interaction viz. year x salinity x genotypes were highly significant for Na+ while all these components were not significant for P. There was strong and significant positive correlation of salinity with Na+ (+0.722** and +0.661**) in both years while the associations were equally strong and significant but negative between salinity and P (-0.159* and -0.234**), K+ (- 0.521** and -0.633**) and K+/Na+ (-0.816** and -0.654**). The negative correlations of protein (-0.146**) and Cl- (- 0.277**) with salinity were significant only during Year 2 and Year 2, respectively. Differential nature of accumulation of different ions and protein at varying levels of salinity was found among the genotypes. The genotypes Sakha-69 and Sids-9 were assessed to be tolerant based on high K+, low Na+ and Cl-, and high K+/Na+ ratio.
