Salinity is becoming a major problem in irrigated agriculture of Pakistan. Ten spring wheat cultivars (Ghaznavi-98, Ogab-2000, Tatara, Takbeer, Fakhr-e-Sarhad, Ingilab, SARC-3, Chanab-2000, Dera-98, and Nowshera-96), representing five different breeding programs were evaluated for salinity tolerance using three saline hydroponic levels: 0, 6 and l2deci-siemen meter -1 (dSm-1), at NWFP Agricultural University. Peshawar during 2002-2003. A split-plot treatment arrangement in a completely randomized design with salinity levels as main-plots and wheat cultivars as sub-plots, was used. Data recorded on shoot and root weight seedling height and leaves plant-1 showed highly significant differences (P-1 vs 60 to 78% at 12dSm-1 level compared to the control. Root weight plant was reduced from 17 to 51% and 57 to 76% under 6 and l2dSm-1, respectively. The results showed 43 and 71% reduction in shoot and root weight when all ten cultivars were averaged at l2dSm-1. Seedling height and leaves plant of wheat cultivars were 29 and 35% less under salinity level of l2dSm-` indicating adverse effect of salinity on wheat growth and development. Three of the ten cultivars evaluated (Ogab-2000. Tatara and Gaznavi-98) exhibited least reduction in all growth traits indicating more salt tolerance than either contemporary wheat cultivars.
