Optimum salt concentration was 10,000 ppm. Shoot and root dry weight had high direct effects to visual score, and the shoot dry weight related to number of leaves/plant. Root dry weight and number of leaves/plant of seedling obtained from nutrient solution were related to grain yield and yield components grown in saline soil. From fifteen wheat varieties tested; Insee 1, Sonalika, SW 95 and SW 23 were salt tolerant, no. 84, SW 91 and SW 93 were salt susceptible based on the results from nutrient solution. When wheat yield and yield components obtained from saline soil condition were considered, SW 23, Insee 1, no. 1015 and Sonalika were classified into salt tolerance group whereas SW 91 and Insee 2 were classified into salt susceptible group. However, when the results from two conditions were combined, Insee 1 and SW 23 were the most salt tolerant varieties and SW 91 was salt susceptible variety. It was concluded that root dry weight and number of leaves/plant could be used to screen salt tolerance of wheat in seedling grown in nutrient solution.
