Abstract

Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Evolution of salt tolerance genotypes is one of the major techniques to overcome this problem. Therefore, present investigation was under taken to screen out twelve (12) wheat genotypes at seedling stage under four level of salt stress 150, 250,350 mMNaCl including one control condition. Salinity treatments (150, 250 and 350) were achieved by adding NaCl in deionized water. All the wheat genotypes were moderately susceptible except the approved varieties (Sehar-06, Fareed-06 and Miraj-08) which were tolerant to different salinity levels. It is evident from the findings that salinity could decrease chlorophyll contents, root length, shoot length, root fresh weight, root dry weight, shoot fresh weight and shoot dry weight of wheat genotypes. Also, at low concentration of salt, all the genotypes gave better performance (<200 mMNaCl solution) and can best grow at low salty areas although approved varieties can be used in next breeding program because they are highly tolerant to salinity.
