Thirty three genotypes of tomato including three checks (NS-515, Arka Rakshak and US-440) were analysed to determine their tolerance levels against salt stress. Four different concentrations of NaCl viz., 50mM, 75mM, 100 mM and 150mM were used along with control. Significant varietal and or salinity treatment effects were recorded on germination percentage, germination rate, root length, shoot length, root dry weight and shoot dry weight. With increasing concentration of NaCl growth parameters of tomato genotypes decreased proportionately. Among the commercial checks NS-516 while among crosses EC-619982 × EC-520078, EC-619982 × Pusa Ruby, EC-620428 × Punjab Chhuhara, EC-620360 × EC-620557, EC-620407 × Punjab Chhuhara and EC-608415 × Arka Saurabh responded positively against different NaCl concentrations. Confirmatory studies may be performed to access their potential under pot cultures before the internal physiological investigations for their variable response.
