Response to salinity was assessed for the traits like shoot length, root length, fresh shoot weight, fresh root weight, Na+, K+ and K+/Na+ ratio in 44 wheat accessions. Absolute mean values were subjected to analysis of variance. All the traits differed significantly (P less than 0.001) for the three NaCl concentrations, 44 accessions and accessions x concentrations except K+/Na+ ratio (insignificant for accessions), while shoot length and K+ appeared significant (P less than 0.01) for interaction. There was highly significant negative correlations between Na+ content and seedling traits and highly significant positive correlations among K+, K+/Na+ ratio and seedling traits. The genotypes i.e., 18187-II, 18180-II, 18194-II, 18203-II, K-65 (standard), 18183-II, and DN-5 with good performance for these traits could be used in breeding programme to develop salt tolerant wheat genotype.
