Abstract
Wheat (Triticum aestivum L.) is a strategic cereal crop whose technological quality is strongly influenced by both genetic background and environmental factors. This study aimed to evaluate the quality performance of five bread wheat cultivars grown under the ecological conditions of Karacabey, Bursa, during the 2023 and 2024 production seasons. Field trials were conducted in a randomized complete block design with three replications, and standard agronomic practices were applied. Grain quality traits including protein content, wet and dry gluten, Gluten Index, Zeleny and delayed sedimentation, SDS-sedimentation, Falling Number, hectoliter, and moisture content were determined according to international standard methods (ICC, AACC). Analysis of variance revealed highly significant (P<0.01) cultivar effects for most traits across both years, particularly for protein content, gluten strength, sedimentation values, and hectoliter. Environmental variation between years significantly affected protein content, sedimentation values, dry gluten, hectoliter and grain moisture, highlighting the influence of rainfall distribution and temperature patterns during grain filling. However, the year × cultivar interaction was not significant for any trait, indicating stable cultivar performance across years. Among the cultivars, Mihalca and Karatopak consistently exhibited superior technological quality, whereas Lider cultivar showed the lowest performance. These findings emphasize the joint role of genetic potential and climatic variation in shaping wheat quality and suggest that cultivars combining high protein content and strong gluten properties are most suitable for sustainable high-quality wheat production in the Marmara Region under changing climate conditions.
