Abstract
The research aiming to identify the sources of group resistance to the main diseases of soft winter wheat was carried out during the period of 2016-2020 in the Eastern Ukraine. Among the main pathogens, the resistance of varieties to septoria blight, hard smut, powdery mildew and tan spot or yellow spot was investigated. On infectious and provocative backgrounds, the sources with stable manifestation of trait of disease resistance under different meteorological conditions were identified according to the hydrothermal coefficient. The sources characterized by individual and group resistance (7 scores) and high resistance (8 points) to tan spot, septoria blight, powdery mildew and hard smut were identified. 35 varieties of soft winter wheat with individual resistance and 12 varieties with group resistance to diseases were selected. Varieties of soft winter wheat L 77-19, Koshova and Krasa Laniv were singled out. They are valuable as the sources with high yield and grain quality and complex resistance to diseases.During the research period, 12 sources with group resistance to diseases were identified: L 139-03 (resistance to hard smut and powdery mildew); L 165-02, LUV 148, Dobirna, Koshova, Ilona and Matrix (resistance to tan spot and powdery mildew); L 77-19, L 77-27 and Darunok Podillia (resistance to tan spot and hard smut); Krasa Laniv (resistance to tan spot, hard smut and powdery mildew); Figura (resistance to septoria blight, tan spot and powdery mildew). Among the sources with group resistance to diseases, the varieties of soft winter wheat L 139-03, L 165-02, L 77-19, LUV 148, Koshova, Krasa Laniv and Figura were characterized by high productive potential, the average yield of these varieties was over 800 g/m2. According to grain quality of soft winter wheat, the varieties with group resistance can be singled out: by protein content in grain – Darunok Podillia, L 165-02, L 77-19, L 77-27, Krasa Laniv and Matrix (over 13.5%); by gluten content – L 165-02, L 77-19, L 77-27, Krasa Laniv and Matrix (over 29%); by the quality of gluten – L 139-03, Koshova and Krasa Laniv (less than 76 units), which belong to the first quality group.
