Variations among 45 wheat genotypes were studied on multivariate scale through Mahalanobis’ D2 statistics at saline and non-saline environments. In the both environment, the genotypes were grouped themselves into five different clusters. Number of genotypes in each cluster varied with the environments. In non-saline environment, cluster II was the largest having 13 genotypes. While, under saline condition, the cluster II also had the highest number of genotypes (16). The distance within cluster were always less than the distances between clusters. The cluster III and IV, I and V and II and V exhibited wide distance between them in non saline, Again cluster III and IV, I and V, I and II and IV and V were distinctly different from others. Cluster mean for yield and its components indicated that twelve genotypes in the cluster V had good performance under non-saline and five genotypes under saline in the cluster IV had good performance. Number of spikes per plant and days to maturity in non-saline environment and number of grains per spike and days to heading in saline environment contributed maximum towards divergence among 45 genotypes.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22216 J.

Salt stress impact was appraised on different antioxidative enzymes, MDA and H2O2 in ten spring wheat cultivars i.e., S-24, Lasani, Fsd-2008, Saher-2006, Inqlab-91, AARI-10, P.B-18, S.H-20, M.P-65, and G.A-20 when salinity applied at the seedling stage. The wheat cultivars were grown under saline (150 mM) and non-saline regimes (0 mM) in pots filled with sand. Diverse response in all wheat cultivars was observed in different studied attributes. Saline stress markedly decline SOD, CAT and POD conc. in different wheat cultivars. While some cultivars (S-24, Lasani, AARI-10 and GA-20) showed increase in these attributes under saline condition as compared to control. MDA and H2O2 content were increased in different wheat cultivars due to imposition of salt stress at the seedling stage. Whereas decrease in some cultivars was recorded in these attributes under saline regime than in non-saline conditions. Of all wheat cultivars, S-24, Lasani, AARI-10 and GA-20 showed high antioxidative activity, less lipid peroxidation and H2O2 content in plant shoot when salt stress applied at the seedling stage. On the basis of higher antioxidative activity and less MDA and H2O2 content, these four cultivars (S-24, Lasani, AARI-10 and GA-20) could be categorized as salt tolerant as compared to others
