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.

Twenty genotypes triticale were evaluated in an alpha lattice design and RCBD for eight characters to a comparison of the relative efficiency (RE) of alpha-lattice design and RCBD. Two experiments were analyzed according to alpha lattice design and RCB design. Average estimated (RE) was 12.97, 5.93, 21.79, 35.50, 21.53, 23.96 and 26.69% for number of plants / m2, tillering fertility, plant height (cm), spike length (cm), number of spikelets / spike, 1000-grain weight (g) and grain yield (g / m2), respectively, the high precision is obtained significantly to estimate treatment effects indicating that using an alpha lattice design in place of RCBD. Mean comparisons for both RCBD and alpha lattice design were performed and two designs confirmed to Dublet, Ulyana, 131/1656 and C259 genotypes were the highest yield (g / m2). Cluster analysis showed that genotypes were isolated into three principle groups and one of these contains one variety (Dublet). This variety was characterized by a high yield over two years. The results showed that alpha lattice more efficient and it can be used it instead of traditional RCB design in the agricultural field trials.
