Abstract: The purpose of research is to study the dynamics of protein content in the grain of spring wheat of Siberian selection in the forest-steppe conditions of the Krasnoyarsk Region and to determine the most stable varieties in terms of its accumulation. The experiments were carried out in 2016–2022. The objects of the study are five varieties of soft spring wheat, zoned in the Krasnoyarsk Region: Novosibirskaya 29, Novosibirskaya 31, Krasnoyarskaya 12, Pamyati Vavenkova and Altayskaya 75, according to the quality group belonging to valuable and strong wheat. Among the varieties studied, the Novosibirskaya 29 variety had the highest average protein content in grain. The lowest grain protein content was noted in the Krasnoyarskaya 12 variety. In general, the protein content varied predominantly weakly over the years (V = 8 %), with the exception of the varieties Krasnoyarskaya 12 and Pamyati Vavenkova (V = 11–13 %), which indicates the stability of the indicator under the conditions of the forest-steppe zone of the Krasnoyarsk Region. Analysis of variance showed that the protein content in spring wheat grain statistically significantly (p < 0.001) depends on the variety and year conditions. The indicator of the strength of influence of the factor “variety” on protein content is 17.6 %, the strength of influence of the factor “year” is 59.2 %. Of the studied varieties, for the stable production of grain with the highest protein content in the forest-steppe of the Krasnoyarsk Region, the Novosibirskaya 29 variety is recommended, since it forms high-protein grain regardless of the weather conditions of the growing season and is the most environmentally stable.
