Cowpea (Vigna unguiculata (L.) Walp.) is one of the most important grain legumes worldwide, and its production is affected by increasing soil salinity due to global climate change. In the present study, fourteen genotypes were tested for their salt tolerance at different concentrations of salinity; 0, 100, 150 and 200 mM of NaCl. The relative shoot length, relative fresh weight of whole plant, fresh root weight, relative water content, electrolyte leakage, malondialdehyde (MDA), proline and chlorophyll parameters were investigated. The results showed that growth of seedling, photosynthetic pigments parameters, relative water content were decreased significantly, and MDA, proline content and electrolyte leakage were increased under salinity stress compared to the control circumstances. This study revealed that KBC-2 and KM-5 amongst the fourteen genotypes showed salinity stress tolerance. These two salt tolerant genotypes KBC-2 and KM-5 can be used further in breeding program to develop salt tolerance in cowpea lines.
