dc.description.abstract Wheat genotypes were evaluated for salt stress at early seedling stage (solution culture) and maturity (pot culture) at Crop Physiology and Ecology Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. Shoot length, root length, root to shoot length ratio and seedling dry weight of 15 days old seedlings were found to be reduced at 12 dS m-1 salinity level compared to control condition. Based on seedling dry weight Shatabdi, BARI Gom 25, BARI Gom 26, BAW 1111, BAW 1146, BAW 1154 and BAW 1156 were identified as salt tolerant (STI = >0.70); BAW 1130, BAW 1135 and BAW 1142 were salt sensitive (STI = <0.60) and other ten were screened as moderately salt tolerant (STI = 0.60 to 0.70) wheat genotypes. Out of twenty genotypes, two salt tolerant (Shatabdi and BARI Gom 25) and two salt sensitive (BAW 1130 and BAW 1142) wheat genotypes were grown in pot irrigated with three levels of saline water (control, 6 dS m-1 and 12 dS m-1). Salt tolerant wheat genotypes maintained lower level of leaf Na, higher level of leaf K, greater K to Na ratio, increased level of flag leaf proline and greater flag leaf SPAD value in saline condition than the sensitive ones. Salt sensitive genotypes affected more in spikes plant-1, grains spike-1, grain dry weight spike-1, 100 grain weight and grain yield plant-1 under saline condition than salt tolerant genotypes. en_US
