Abstract. The purpose of the study is to evaluate a new variety of winter triticale Sudogda according to economic and biological characteristics and properties. The variety was created by the method of mass selection of highly productive plants resistant to lodging, brown and stem rusts from the breeding line L6, obtained from the Voronezh Federal Agrarian Scientific Center named after V. V. Dokuchaev. The selection of material and its study were carried out in the soil and climatic conditions of the Central Non-Chernozem zone according to the generally accepted scheme of the breeding process for winter crops. Results. A detailed morphological description is given and the results of the study of the new variety Sudogda in competitive variety testing on light soddy-podzolic, slightly acidic soils with a low content of organic matter (1.3 %) are presented. The average yield of the Sudogda variety was 4.68 t/ha (+0.54 t/ha to the Doktrina 110 standard), the maximum yield in the favorable year of 2017 on soddy-podzolic soils reached 5.5 t/ha, on gray forest soils 6.5 t/ha, the minimum – in the dry year of 2016 3.5 t/ha (+0.47 t/ha to the standard). The variety is characterized by high winter hardiness (95 %), resistance to lodging (5.0 points), drought resistance (4.5 points). During the years of variety testing, the variety showed tolerance to brown and stem rusts, and was moderately affected by leaf septoria at the standard level. It is distinguished by high indicators of the physical qualities of grain: the weight of 1000 grains is on average 40.4 g, the nature of the grain is 704 g/l, the vitreousness is 79 %. The protein content in the grain is 15 %, which is 0.5 % higher than the standard. The variety is intended for use in grain fodder. It is recommended for cultivation on all types of soils, but tolerates light slightly acidic soddy-podzolic sandy loamy soils better than other varieties. The new variety Sudogda has been included in the State Register of Breeding Achievements of the Russian Federation since 2021 and approved for use in the North-West region, where it showed a maximum yield of 6.96 t/ha. Scientific novelty. A new plastic, mid-season, stress-resistant variety of winter triticale has been created, which is distinguished by the ability to form a high grain yield on light soddy-podzolic, slightly acidic soils of the North-West region of the Russian Federation.
