The results of a comparative evaluation of winter and spring wheat genetic material in the soil and climatic conditions of the Middle Priamurye Region are presented. Eight varieties of winter wheat bred in Zernograd Agricultural Research Institute were compared to varieties and lines of spring wheat bred in the Far East Agricultural Research Institute. It was found that regional conditions meet winter wheat biological requirements completely and are favorable for productivity features. Under optimal hydrothermal conditions, the productivity of winter wheat varieties is within 30.6–58.4 dt ha–¹, which is 22.3–75.0% higher than spring wheat’s due to a higher 1000 seed weight. On average over the years of research, 1000 seed weight of winter wheat was 35.0–41.0 g, while that of spring wheat was 29.7–36.6 g. In the local conditions, spring wheat’s grain quality is higher than that of winter wheat varieties. Spring wheat varieties and breeding lines surpass winter wheat crops in protein content by 2.5%.
