A pot experiment was conducted to evaluate performance of Upland cotton (Gossypium hirsutum L.)varieties, (A118), Aleppo33/1 (A33/1), Aleppo90 (A90), Raqqa5 (Raq5) and Deir-Ezzor22 (DE22), grown under different salinity concentration 0, 50, 100 and 200 mM NaCl for 56 days. Results indicated that increasing salinity decreased fresh and dry leaf and root weights. Also, leaf K+/Na+ ratio was decreased as increasing salinity levels in all tested varieties. This reduction for the all indicators tested was relatively more pronounced in A118 than DE22. Thereby, DE22 variety relatively performed better under salinity compared to the other tested varieties. Based on this investigation, it can be concluded that DE22 and Raq5 are relatively characterized as salt tolerant, while A90 as moderate salt tolerant. On the other hand, A118 and A33/1 could be considered as salt sensitive.
