Twenty-one genotypes of bread wheat (Triticum aestivum L.) were used in this study, which were planted in three locations (Hawija, Al-Alam, and Baladruz) within the governorates of Kirkuk, Salah Al-Din and Diyala in Iraq, using a complete random block design and with three replications. Data were recorded on the characteristics; number of days to spikes, plant height, leaf area, number of grains per spike, number of spikes per plant, weight of 1000 grains, grain yield, biological yield, harvest index, protein content and gluten content.  Genotype 38 exceeded all genotypes in earliness of heading (101.6 days), number of grains per spike (60.8), number of spikes (561.4 spikes/m-2), weight of a thousand grains (51.9 g), grain yield (923.7 g), the biological yield (2099 g), harvest index (44) and protein and gluten percentages (16.8 and 66.6%) respectively, also this genotypes was tolerant to yellow rust, and according to the interaction between genotypes and locations, the genotype 38 showed its superiority in most important characteristics, including the grain yield over the three locations, so it could be recommend and launched as a vareity of bread wheat in agriculture.

Key words:  Bread wheat, Genotypes, Yellow rust, Grain Yield.
