This study includedtwenty samples of spring triticale, including Russian and foreign varieties (Grebeshok (standard), Lana, Pamyati Merezhko, Ukro, Ulyana, Khlebodar Kharkovsky, Yarilo, Dublet, Legalo, Sandro) and 10 breeding lines (131/7, 131/714, С259, С238, 6-35-5, Л8665, 131/1656, П2-13-5-2, ПЛ-13-5-13, П2-16-20) in terms of ecological stability of the productivity, content protein in grain and gluten content. Varieties Grebeshok, in memory of Merezhko and line 131/714 are responsive to favorable environmental conditions according to all the studied characters. The remaining samples for individual indicators belonged to both the plastic group and the groups of high and / or low responsiveness.
Grouping by classes of plasticity, high and low responsive to favorable environmental conditions showed a negative correlation between classes based on yield and classes based on protein content in grain and gluten content (r = -0.31 and r = -0.49, respectively) and in at the same time, there is a high correlation between the classes in protein content in grain and gluten content (r = 0.86).
Based on the study, promising samples were identified: by yield: Ukro, Ulyana, Khlebodar Kharkov, Dublet, 131/1656; by protein content in grain: Yarilo, Sandro, Lana, 131/7, 131/714, P2-13-5-2, P2-16-20; gluten content: Yarilo, Sandro, 131/7, 131/714, C238, L8665, P2-13-5-2, P2-16-20, which can be recommended for inclusion in breeding programs according to these characteristics.
