Inter- and Intra-Varietal Variations in Wheat (Triticum aestivum L.) Under Saline Conditions

M. Ahsan and D. Wright    

Abstract: Three wheat varieties (Kharchia-65, KRL 1-4and Alexandria) were tested for their salt tolerance at 125 mol m3 NaCl salinity. Inter- and intra-varietal variations in these wheat varieties were also investigated for ion contents (Na+, K+, CI), K+ /Na+ ratio, yield and yield components under saline conditions. Although environmental conditions were uniform , but variability within varieties was found to higher than the variability between varieties. KRL1-4 was found salt tolerant than Kharchia-65 and Alexandria under saline conditions. These inter-and intra-varietal variations suggested that improvement for salt tolerance might be achieved through selection from within already existing varieties and, or by crossing salt tolerant and salt sensitive wheat genotypes.
