Abstract. The purpose of the study was to breed a new highly productive variety of spring common wheat for the conditions of the Middle Volga region, to assess its economically valuable traits, adaptability, and resistance to pathogens. The work was performed in 2017–2020 in the forest-steppe zone of the Samara region. The new promising variety Kinelskaya 2020 was studied in comparison with the regionalized varieties Kinelskaya Niva (standard) and Kinelskaya Yubileynaya according to the methodology of State Variety Testing. The genotype was bred by hybridization (L-503/Tulaykovskaya 1 // complex hybrid K-34376) according to the classical breeding scheme. The promising variety Kinelskaya 2020 is distinguished by consistently high grain productivity of 2.25–4.01 t/ha; the average increase to the standard was 0.35 t/ha, or 12.4%. Under conditions of sufficient moisturization (2017), it reached 0.54 t/ha; the increase to Kinelskaya Yubileynaya variety was 0.27 t/ha. The adaptability of the promising variety was 111.4%, which was 12.4% higher than that of the standard; the adaptability of Kinelskaya Yubileynaya variety was 2.7% higher. Productive bushiness on average over the years of the study was 1.9 pcs (for the standard, it was 1.5 pcs); in a favourable year, it reached 2.1 pcs. The productive plant density of Kinelskaya 2020 before harvesting averaged 522 pcs/m2, which was 51 pcs/m2 higher than that of the standard. The mass of 1000 grains varied from 35.5 g (dry year) to 41.2 g (moisture-rich year). Kinelskaya 2020 was distinguished by a stable flour strength over the years (283–386 a.u.), a large quantity of grain units (827–850 g/L), and high gluten content in grain (25.2–31.8%) of the second quality group (89–99 RLI units). The overall bakery score was 4.3 points, which corresponded to the values of the valuable variety. Kinelskaya 2020 has been submitted for State testing in the Middle Volga region of the Russian Federation since 2021.
