Seedling vigour evaluation study was conducted to assess the tolerant range of different genotypes of Brinjal under different Sodium chloride salinity stress conditions. The salinity stress was simulated by using different concentration of sodium chloride solution viz., 0.25,0.50, 0.75, 1.0 % concentration along with 8 ml of 0.1 milli molar (mM) calcium sulphate as control. Germination percentage and seedling vigour were declined with increasing levels of salinity stress in all the twenty genotypes. Among the twenty genotypes five genotypes namely IC112589, IC126784, IC203585, IC90774, IC112960 showed maximum tolerance for salinity stress at 0.25 % level. The performance of the line IC 111589 alone was found to be better by recording higher germination percentage of 64,26,and 14 and seedling vigour index of 150.3; 40.6 and 6.2 at 0.25 %; 0.50% and 0.75% sodium chloride concentration respectively.
