Sowing spring triticale based on mixtures of varieties may be more promising than sowing monoculture varieties. Four varieties of spring triticale (Ulyana, Rovnya, Saur and Khaikar) were evaluated with two-component (1:1) and three-component (1:1:1) variety mixtures. Studied 6 variants of two-component mixtures and 4 three-component mixtures. The research was carried out on the experimental field of the Chuvash State University in 2018-2020. The effectiveness of the variety mixtures was determined by a comparative analysis of the actual and possible yield. The stability of crops in terms of yield was assessed by the coefficient of variation. In monoculture, the Saur variety had the highest yield. The two-component crops were the highest yielding and stable over the years compared to the one-component and three-component crops. The most promising variety mixtures turned out to be Ulyana/Khaikar, Rovnya/Saur and Saur/Khaikar, which allow increasing yields by 4.7-20.2 100kg/ha.
