A pot culture experiment was carried out in Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during the period from November 2001 to March 2002 to investigate the effect of salinity stresses on canopy structure, yield and yield attributes of three varieties of wheat e.g. shotabdi, kanchan and gourob. The plants were subjected to grow under five salinity levels, 0.6 (control), 2.6, 5.2, 8.2 and 11.0 dSrn-1 imposed' by crude sodium chloride salt. Increasing salinity levels significantly decreased plant height, number of total tiller per hill, number of effective tiller per hill, length of spike, number of grain per spike, grain weight, straw yield, grain yield and harvest index compared to control. Salt tolerant capability varied among varieties and shotabdi was the best for canopy growth, yield and Yield attributes over the rest. The per cent decrease of grain yield and harvest index were the highest in gourob, medium in kanchon and the lowest in shotabdi. Thus shotabdi was found salt tolerant variety than others.
