A laboratory experiment was conducted at Plant Physiology Division, Bangladesh Agricultural Research Institute (BARI) during rabi season of 2013-2014 to evaluate the response of 36 wheat genotypes to different levels of salinity and to find out the salt tolerant genotype(s) for saline areas. The treatments consisted of thirty six wheat genotypes and four levels of salinity (0, 5, 10 and 15 dS m-1) in complete randomized design (CRD) with three replications. The plant growth media was used in Hoagland solution with pH 6.0. Distilled water was used as a control (0 dS m-1) treatment. The results showed that germination percentage, seedling root and shoot dry weight and vigour index were found to be affected by different levels of salinity. Among the tested genotypes of wheat, BWSN E-15, PYT E-14 (BAW-1193), CVD E-5 (BAW-1135), CVD E-9 (BAW-1151), CVD E-10 (BAW-1157), CVD E-11(BAW-1161) , CVD E-12 (BAW-1163) and PYT E-15 showed better performance up to 10 dS m-1 as evaluated on the basis of germination percentage, seedling growth, seedling dry weight and vigour index.

Key words: Screening, Wheat genotypes and Salinity.
