Five wheat genotypes (SI-91195, N-41, N-1076, N-886 and SD-1200/14)were evaluated under different salinity levels (control, 6.0, 9.0 dS m-1) incemented tanks filled with river sand. The objectives of the study were tosee the salinity tolerance and solute accumulation (organic and inorganic),of different genotypes for turgor maintenance at varying salinity levels.Growth performance was recorded at the time of harvest. The genotype N-41 performed better at high salinity level (i.e. 9 dS m-1) in terms of plantheight, biomass plant-1, spike length, number of grains plant-1 and 1000-grain weight, followed by N-1076, SI-91195 and SD-1200/14. Theperformance of N-886 was comparatively poor, at higher salinity levels. Theadaptability of good performing genotypes might be due to the lowaccumulation of Na, resulting in high K/Na ratio and the higheraccumulation of proline for the turgor maintenance.
