Durum wheat (Triticum turgidum L. var durum) is an indigenous predominant tetraploid wheat species in Ethiopia. Ten released durum wheat varieties were evaluated during 2016 and 2017 main cropping seasons at five districts representing various agro-ecologies of northwestern Ethiopia. The experiment was laid-out using Randomized Complete Block Design, replicated three times. Grain yield and protein contents (%) of entries were scored and the ANOVAs were performed for the traits under study. Additive Main effect and Multiplicative Interaction (AMMI) model was used to determine the stability of the genotypes across environments. Analysis of variance revealed a significant difference among the tested varieties for the grain yield in all tested locations. The AMMI analysis of variance of the grain yield showed that the presence of a highly significant difference among genotypes, environments and genotype–environment interaction with the contribution of 10%, 75.6% and 14.4% of the total sum of square variance, respectively. Genotypes Denbi, OBSA and Tate were identified as the most stable genotypes. Mukiye and Utuba recommend for Shebel Berenta; Filakit and TOLTU recommend for Debre; Elias and Mangudo recommended for Wonberema woreda.
