Abstract

This study was carried out during the years 2001 and 2004 to determine the inheritance of important agronomical and quality traits and also the correlations between these traits in durum wheat. The research, studies concluded that genotypical variance is important with regard to spike length, number of spikelet per spike and test weight and that the useful selections could be made with respect to these traits. Environmental variance was found important for seed number per spike, seed weight per spike and thousand kernel weight, while the variance component of genotype x environment was found important for seed yield, gluten content and protein content. Environmental and genotype x environment variances were determined to be important for SDS-sedimentation.
