Three genotypes of wheat differing in salt tolerance were evaluated for salt tolerance and physiological responses in sand culture under natural conditions. Higher salt tolerance of Kharchia 65 was indicated by its lower slope, lower concentrations of Na+ and Cl-, higher potassium selectivity and better maintenance of tissue hydration. Salt sensitivity of HD 4502 was due to higher Na+ and Cl-, lower K+ and lower degree of tissue hydration while that of HD 2160 x Kharchia was due to higher Cl- concentrations.
