In: Assiut Journal of Agricultural Sciences 2008.v.39(3)Summary: This study was carried out during the three successive seasons of 2004/2005, 2005/2006 and 2006/2007 at the Experimental Farm of Faculty of Agriculture, Sohag University, Egypt. Two durum wheat populations (Triticum durum L.) in F₃ generation of the crosses Chahba 88 x Bani-Swief I and Carcomun x Sohag 3 were used in this investigation. One hundred F] families underwent pedigree selection in the F₁ basic materials. The best plant from each of the best 20 families for each selection criterion. namely days to heading, greater IDO-kernel weigh! and higher grain yield were saved to give the F₃ families. The analysis of variance showed highly significant differences between F₃ families in both populations and satisfactory genotypic coefficients of variation were detected for some traits.
