الملخص الإنجليزي

Half diallel crossing program was carried out by using six wheat bread genotypes ( Al-izz,Saberbaek,Entesar,Abo-ghraib,Tooz and Sabah) according to griffing approach (1956)to investigate the genetic differences of grain yield and its components.F1s(were obtaived in 2013 season)and their parents were grown in 2014 season at the from in Tooz district\Salahddin grovernorate by using Randomize completely block design with three replications.

Resulte showed highly significant differences among genotypes in all traits studied,while(Abo-ghraib*Sabah)and (Al-izz*Sabah)crosses were suprier in grain yield and its components,and siginificant hybrid vigor in wheat grain yield parent(Sabah6)was agood cambiner in spike length and grain yield.spicific combining ability of Saberbaiek*Tooz ,Entesar*Sabah and Tooz*Sabah was significant in grain yield and harvest index,and other crosses (Al-izz*Abo-Graib,Al-izz*Sabah,Entesar*Abo-Graib and Entesar*Tooz)in both biological yield and grain yield.Dominance varation was important in days to emergarce and specific grain weight .Grain yield and its components were controlled by additive gene action and have apartial dominance while, days to emergence,plant height,specific grain weight and harvest index have over dominance otherwise,expected genetic advance was high in spike length and moderat in grain yield.plant though principle component analysis exhibited that 0.432 of differences among genotypes caused by grain yield followed by 0.134 of specific grain weigth and 0.127 by spike length therefore, The application of selection on spike length and grain yield can be effective in improving wheat grain yield
