The breeding materials used in this study were the F₃, F₄ and F₅ generations of two durum wheat crosses, to improve grain yield using four selection criteria with pedigree selection.  Differences between F₃ families were highly significant in both populations and satisfactory genotypic coefficients of variation were detected for the selection criteria i.e., grain yield, no. of spikes/plant, no. of kernels/spike and 1000-kernel weight. The results indicated that selection for no. of spikes/plant improved it by 13.33 and 12.09% from the bulk sample and the check cultivar after two cycles of selection in population I, respectively. Such increase was accompanied with increasing no. of kernels/spike (5.29%), 1000-kernel weight (4.88%), grain yield/plant (12.08%) and biological yield/plant (19.45%), and decreasing heading date (1.56%) and plant height (2.13%) from the bulk sample.  Selection for no. of kernels/spike after two cycles of pedigree selection increased the criterion of selection by 11.63 and 17.86% for pop < /p>
