The aim of this study was to evaluate grain yield, ecological plasticity, and stability of ten durum wheat (Triticum durum Desf.) cultivars in multi-environment trials in terms of their suitability for dissemination under the conditions of the Western region of Ukraine. Field experiments were conducted over two growing seasons (2023-2024 and 2024-2025) at three agroecologically distinct locations, which in combination with years constituted six environments. Grain yield data were analyzed using combined analysis of variance and parametric stability approaches, including the Eberhart-Russell regression model and a set of nine stability parameters. The ANOVA results revealed a predominant contribution of the genotype effect to grain yield formation (over 90% of the total variation), while the effects of environment and genotype × environment interaction were statistically signific..
