A field experiment was carried out in Iraq , during the season 2013-2014, in order to evaluate the performance of different ten genotypes of bread wheat in irrigated field conditions, according to the design of randomized complete block in three replications. The results indicated the existence of genetic variability, in a significant manner (at the level 5%), in the response of the studied genotypes to the conditions of the field for all of the traits such as plant height (cm), number of tillers per plant, number of spikes per unit area, spike length (cm), weight of spikes per stem and thousand grains weight (g). Both Egyptian and American genotypes gave the highest grain yield which reached to 4.84, 4.66 tons hectare -1 respectively. While both genotypes Apa-99 and Synthetic-10 gave less grain yield 2.62, 2.60 tons hectare -1 respectively. The study showed the importance of the number of grains per spike and the thousand grains weight due to their positive and high significant correlation with the grain yield, so it can be used as indicators of suitable selection for the development of high- yielding genotypes.
