To evaluate salt-tolerance of triticale genotypes, experiments were conducted as factorial design based on a completely randomized design with four replications at germination stage and hydroponics greenhouse planting. At germination stage, 41 triticale genotypes, 'Kavir' cultivar of bread wheat, and 'Dipper-6' cultivar of durum wheat (as salt-tolerant genotypes) included as the first factor while the six salinity levels: 0, 0.5, 1, 1.5, 2, and 2.5 percents of NaCl were the second factor. In greenhouse experiment, four salt-tolerant triticale genotypes including 'Caracal', 'Prego', 'Lasko', and 'Zorro' and two salt-sensitive genotypes of 'Pollmer' and 'Alamos-83' were used (base on the result of germination experiment), while 'Kavir' cultivar of bread wheat and 'Dipper-6' cultivar of durum wheat were also used as the first factor (total of eight genotypes) and four salinity levels 0, 0.5, 1 and 1.5 percents of NaCl were the second factor. Results evaluation of salinity tolerance at germination stage indicated that the increase of salinity levels has lead to a significant decrease in germination percent, the number, weight and length of roots of germinated seeds, and the number and weight of shoot of germinated seeds. Also, salinity genotype interaction for the studied traits was highly significant. 'Kavir' and 'Dipper-6' had less salt-tolerance compared to triticale genotypes in the germination stage. The genotypes 'Caracal', 'Prego', 'Lasko' and 'Zorro' had least percentage of traits reduction in different salinity levels compared to control treat, hence, were introduced as salt-tolerant triticale genotypes at the germination stage. Genotypes 'Pollmer', 'Alamos-83' and 'Magnat' had higher of traits reduction in different salinity levels compared to control, hence, were introduced as salt-sensitive triticale genotypes at the germination stage. The results of analysis of variance in greenhouse experiment showed that salinity had significant effect on all evaluated trait of this experiment in such a way it caused significant decrease in the number of leaves, number of tillers, number of roots, length of roots, dry weight of shoot, dry weight of root, ratio of shoot dry weight to root dry weight, K + concentration in shoot, K + concentration in root, and K + /Na + ratio in shoot root. On the other hand, salinity caused to an increase in Na + concentration in shoot and root, the ratio of K + in shoot
