A pot experiment was carried out to study the effect of salinity stress on seeds germination and plants growth of Coriander (Coriandrum sativum L.)by the selection method. For this purpose, four treatments of different concentrations of NaCl were used, namely, 0, 1000, 2000, 3000, and 4000 ppm of NaCl. The following parameters of: seeds germination, roots number and length, plant strength, number of leaves, plant length, shoot tip necrosis, and the percentage of survivals were recorded. The Obtained results showed that all growth parameters were reduced by increasing the NaCl concentration except for the percentage of shoot tip necrosis which was increased with a significant difference among all treatments. Coriander plants were found to resist salinity up to the concentration of 3000 ppm NaCl only.
