Abstract
A study was accomplished in a field experiment at Sakha Agricultural Research Station Farm, to assess 18 bread wheat genotypes (16 promising lines and 2 checks) during 2014/2015 and 2015/2016 seasons over ordinary and salinity soil circumstances. Analysis of variance showed highly significant effects between genotypes and salinity soil treatments. Interaction effects were highly significant between all components of interaction except few cases. There were significant reductions in all studied characters due to salinity circumstances measure up to through normal circumstance. The obtained results showed that Lines 2, 14 and 15 and cultivar Misr 1 were the best genotypes under study. These genotypes had highest values for grain yield and its components under non-saline and/or saline soil conditions. Stress tolerance indices (STI's) results indicated that GMP and STI indexes gave similar ranks for lines 2 and 14 which can identified as salt tolerant genotypes. Lines 8 and 10 were recognized as sensitive genotypes, for reason that their little means for GMP and STI. In the similar situation, the 2 indexes TOL and SSPI ranked the considered genotypes for salt acceptance and indicated that lines 11, 14 and 2 were further tolerant to salinity stress. The correlation analysis Spearman's rank correlation coefficient between the salinity tolerant indices was used. There were highly significant positive correlation with salinity tolerant indices MP, GMP, STI, TOL and SSPI under normal condition. Whereas, at salinity (Ys) conditions correlation was highly significant and positive with salinity tolerant indices MP, HM, GMP, STI, YI and YSI.
