Abstract : The result of various salinity levels (0, 5000 and 8000 ppm) on growth traits, yield and its components and grain quality of transgenic (mannitol-accumulating gene [mtlD] for salt stress tolerance event; 79/8 and non-transgenic (cv. Giza 163) wheat plants were investigated. For substantiative this work, the two genotypes used were subjected to the afore mentioned salinity levels. When compared the event 79/8 with the cv. G-163, significant positive results were obtained with the event 79/8 under zero and 5000 ppm NaCl-salinity as compared to the level of 8000 ppm. Irrespective of the two genotype, growth traits (No. of tillers plant-1, root size plant-1, No. of leaves plant-1, yield and its components (No. of spikes plant-1, spike length, No. of spikelets spike-1, No. of grains spike-1, 1000-grain weight and grains weight plant-1) and grain quality (nutrient status of grains, starch, protein and sugars) in 8000 ppm-NaCl-stressed plants were significantly lower than those in 5000 ppm-NaCl-stressed plants. No significant variations in all aforementioned parameters were found out between 5000 ppm-NaCl-stressed and non-NaCl-stressed plants. Regardless NaCl-stress treatments, all aforesaid characters (growth traits, yield and its components and grain quality) were significantly differed between both 79/8 event and cv. Giza 163 with preferability in behave of the former. The event 79/8 surpassed the cv. G-163 in all determined parameters. The interaction effect of NaCl-stress and also the genotype treatment was significant. Maximum positive results of all parameters under study were obtained with non-NaCl-stressed plants of the event 79/8 followed by plants of the same event under 5000 ppm NaCl stress. It has been recommended that, the transgenic genotype; salinity and drought tolerant must be used in wheat cultivation under the climatic changes occurred nowadays which proved to be increased soil salinization and droughts.
