  Salinization causes degradation in arid zones and irrigated soils, producing negative effects on crops such as tomato (Solanum lycopersicum L.). In order to identify native tomato phenotypes tolerant to salinity, 10 advanced lines were evaluated at three levels of electrical conductivity in Puebla, Mexico. Seeds were sown in Peat moss® substrate in 200-cavity polyethylene trays. They were irrigated with Steiner nutrient solution plus NaCl at 5, 7 and 9 dS∙m- 1. Treatments were set up under a split-plot design and four replications. Salinity at 7 and 9 dS.m-1 compared to 5 dS.m-1 negatively affected: plant height with a reduction of 6.8% and 30.6% respectively; stem diameter 5.8% and 15.3%; number of leaves 2% and 11.1%, and total dry matter production 8.5% and 28.4%.
