Both of them are on the right bank ofEuphrates, distance between on and another is 90 km. The first location is in (sufia) arural area of Ramadi, itssoil is (sandy loam). The second location is in (zakhikha) village in Hit city, its soil (loam sand). Eight durumwheat 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). Thesefactors (8×2) were used as an input with split plot design at three replicates. The aim of the experiments is tounderstand growth and production of these genotypes in there two locations. Genotypes did not differsignificantly in number of tillers, while it significantly differed in plant height, flag leaf length, number ofkernelsspike, weight of 1000 kernels and grain yield at two locations and their means. Mutation 63 gave theupper significance rates in plant height, flag leaf length and weight of 1000 kernels, while mutation 7 resulted inthe highest rate of kernel per spike at the mean of both locations. Mutations (82, 63, 49) gave higher significantrates in grain yield at the mean locations, reached (7.3, 6.8, 6.6) t.ha-1, respectively.Variation of the seeding ratesdid not significantly affect, flag leaf length, spike length and weight of 1000 kernels. Planting of 120 kg.ha-1 seedat 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 reached80.9 cm, 6.0 t.ha-1 respectively. Ramadi - sufia location gave higher significant means in plant height, weight of1000 kernels and grain yield. While Hit - zakhikha location gave higher means in tillers number, flag leaf lengthan number of kernel per spike. Consequently, changing the planting location affects in the growth andproduction of these genotypes, but this depends on the type of soil and climatic conditions, although it has grownnaturally and gave an acceptable economic yield.
