Nineteen cowpea (Vigna unguiculata) genotypes were tested during germination and seedling stages of growth at 4 NaCl concentrations (0, 50, 100 and 200mM). The experimental design was completely randomized design (CRD) in factorial combination with three replications. Data analysis was carried out using SAS (version 9.1) statistical software. Germination percentage (GP), seedling shoot and root traits were evaluated. The analyzed data revealed highly significant (p<0.001) variation among cowpea genotypes, treatments and their interactions. It is found that salt stress significantly decreased root length and shoot length. The extent of decrease varied with accessions and salt concentrations. Most accessions were highly susceptible to 200 mM NaCl concentration. Genotypes 211557 and Asebot were better salt tolerant. The result showed the presence of broad intraspecific genetic variation in cowpea genotypes for salt tolerance. ER -
