Abstract: Two environmental locations in Anbar Governorate have been chosen. Both of them are on the right bank of Euphrates, distance between on and another is 90 km. The first location is in (sufia) arural area of Ramadi, its soil is (sandy loam). The second location is in (zakhikha) village in Hit city, its soil (loam sand). Eight durum wheat genotypes have been planted in December 8, 2010 as (main plots); seven mutations (7, 26, 38, 49, 53, 63, 82) and door 85 cultivar were used. The seeding rates have been used (120, 160) kg.ha-1 as (sub plots). These factors (8×2) were used as an input with split plot design at three replicates. The aim of the experiments is to understand growth and production of these genotypes in there two locations. Genotypes did not differ significantly in number of tillers, while it significantly differed in plant height, flag leaf length, number of kernelsspike, weight of 1000 kernels and grain yield at two locations and their means. Mutation 63 gave the upper significance rates in plant height, flag leaf length and weight of 1000 kernels, while mutation 7 resulted in the highest rate of kernel per spike at the mean of both locations. Mutations (82, 63, 49) gave higher significant rates in grain yield at the mean locations, reached (7.3, 6.8, 6.6) t.ha-1, respectively.Variation of the seeding rates did not significantly affect, flag leaf length, spike length and weight of 1000 kernels. Planting of 120 kg.ha-1 seed at both locations gave upper significance means of tillers number and number of kernel per spike. While using 160 kg.ha-1 seeds resulted in high rates of plant height, grain yield at the mean of both locations which reached 80.9 cm, 6.0 t.ha-1 respectively. Ramadi - sufia location gave higher significant means in plant height, weight of 1000 kernels and grain yield. While Hit - zakhikha location gave higher means in tillers number, flag leaf length an number of kernel per spike. Consequently, changing the planting location affects in the growth and production of these genotypes, but this depends on the type of soil and climatic conditions, although it has grown naturally and gave an acceptable economic yield.
