Abstract: The conducted research demonstrated that the productivity and grain quality of winter bread wheat (Triticum aestivum L.) are strongly influenced by soil and climatic conditions of the growing area. The comparative evaluation of 28 new cultivars across the Steppe, Forest-Steppe, and Polissia zones of Ukraine during the 2022/23–2023/24 growing seasons confirmed the decisive role of environmental factors in the realization of varietal potential. The highest grain yield levels were consistently recorded in the ForestSteppe zone, where favorable moisture and temperature regimes allowed cultivars to fully express their genetic productivity. Lower yield values were observed in the Steppe and Polissia zones, reflecting the limiting effects of drought stress and cooler climatic conditions, respectively. Despite these differences, all tested cultivars exceeded the conditional standard, indicating a generally high yield potential of modern breeding material. Among the studied genotypes, the cultivar DSV 2129120 demonstrated the highest yield performance and relative stability across all agroecological zones, confirming its high adaptive capacity. Grain quality parameters showed clear zonal differentiation. Protein and wet gluten contents were highest in the Steppe and Forest-Steppe zones and declined toward Polissia, which is consistent with established agroecological patterns of wheat grain formation. Cultivars Hapter, Invictus, and Bilotserkivchanka were distinguished by higher and more stable grain quality indicators, making them valuable for both production and breeding purposes. Overall, the results emphasize the importance of zone-specific cultivar selection as a key component of sustainable wheat production under conditions of increasing climatic variability. The identified high-yielding and quality-stable cultivars can be recommended for targeted cultivation in specific agroecological zones of Ukraine, contributing to improved grain production efficiency and agroecosystem resilience.
