The present work was carried on lentil for classifying six new varieties with respect to their salt tolerance degree. Lentil crops were grown in small lysimeters placed in greenhouse and irrigated with saline waters of different concentrations, 0.9 dS m-1 (fresh water, used as a control), 3, 6 and 9 dS m-1. Grain water use efficiency (WUEg) is the agronomic criterion used for ranking the six varieties, it represents the ratio of dry grain lentil to the water consumed by evapotranspiration. For the six studied variety we observed that leaf area, productivity in dry matter in yield, and water consumptive use changed with the salt concentrations. The WUEg obtained as the average of the 4 salinity levels, indicated the ILL5845 variety as the most tolerant one, since it attains the highest WUEg value (1.20 g/kg). The varieties ILL5883, ILL6796, ILL5582 and ILL4400 ranged between moderately and weakly tolerant, since their average WUEg value was 0.89 g/kg. The ILL8006 variety was the one with the lowest WUEg value (0.67 g/kg); moreover its productivity was the lowest both under saline and no saline soil conditions; therefore, because of its poor agronomic performance, it is not recommended under irrigation with saline water.
