Two field experiments were conducted at Al-Oha wheat State Farm, Department of Agriculture and Livestock – Al-Ain, United Arab Emirates, during the two successive seasons of 1996/1997 and 1997/1998, to find out the effect of the different seeding rates on yield, yield components and some other agronomic characters of Mexican wheat cultivar Ceti Serres (7C) and Syrian wheat cultivar Sham 2 .  The results obtained could be summarized as follows: 1-    The two cultivar produced statistically the same grain and straw yields. 2-    Increasing seeding rate decreased each of spike length, number of spikelets/ spike flag leaf area, number of kernels/ spike and spike grain weight but in the same time increased number of spikes /m². However, 1000-grain weight was not affected by the different seeding rates. 3-    Grain and straw yields were not affected by various seeding rates in both seasons.
