The lack of information about the effects of salinity on growth and productivity of triticale prompted us to study the salt tolerance level of 39 triticale lines and barley cultivar subjected to four levels of NaCl: control, 100, 150, 200 mM/L at stem elongation and maturity stages. This study was carried out in greenhouse at ICARDA during 2007, using Randomized Complete design with a factorial arrangement of treatments. Results revealed that the measured characters were affected by NaCl, with an interaction between treatments and lines. The influence of NaCl was observed at the levels 150 and 200 Mm/L more than the 100 Mm/L. Shoot dry weight was affected by salinity more than the root one. NaCl affected the biomass per plant and thousand kernels weight more than plant height, peduncle and spike length At the two harvesting dates the lines: (14, 32, 13, 30, 34, 16, 10, 26, 19, and 22) characterized by the lowest reduction percentages in almost of measured traits
