The study was conducted to evaluate the main grain quality indicators of winter common wheat varieties in the steppe Trans-Volga region and to establish correlations between them. The work was carried out from 2022 to 2024 on ordinary chernozem soil in Samara region, using 12 winter common wheat varieties sown on complete fallow, as part of a competitive variety trial. Agrometeorological conditions in 2022 were characterized by favorable moisture, while drought of varying intensity was observed in 2023 and 2024. The protein content in the grain, the volume of bread, the overall baking score and especially the falling number depended mainly on the genotype (share of the factor influence was 36.3...52.6%), while the rheological properties of the dough depended to a greater extent on the annual conditions (35.2...52.4%). Based on the protein content in the grain and the valorimetric value, most of the studied varieties can be classified as good fillers. Bezenchukskaya 380 (13.5%) and Vyuga (13.1%) met the requirements for valuable wheat in terms of protein content, while Alternativa, Skirda and Vyuga (58...65 unit of valorimeter) met the requirements. The maximum values of the key quality indicator for winter wheat, the “falling number” were observed in varities: Estafeta, Vyuga and Integratsiya (336–363 sec). Based on a set of quality characteristics a new short-stemmed variety of winter soft wheat - Vyuga, was distinguished. Based on the correlation analysis data, criteria for assessing the baking quality of common wheat have been proposed, including dough stability index according Brabender farinograph and grain protein content. The latter may be useful in years with favorable hydrothermal conditions during the winter wheat growing season, when the greatest differentiation in grain protein content occurs among varieties.
