Abstract The creation and use of rust-resistant varieties is the most eco-friendly and efficient method of protecting wheat and triticale crops. For successful selection of spring triticale for rust resistance, it is necessary to have genetic material with efficient genes. In order to identify the carriers of leaf and stem rust-resistant genes, a collection of spring triticale (86 samples) was studied using molecular markers and phytopathology methods. On an artificial infectious background, 81% of collection samples of spring triticale demonstrated a high resistance (0R) to the stem rust population. Nineteen samples that demonstrated a resistance (0–5% R) to the leaf rust population were isolated. Identification of the collection using DNA markers allowed for isolating the samples with Sr2 (19 samples), Sr22 (nine samples), and Lr28 (14 samples) genes. Among the collection, no carriers of Lr9 and Lr35/Sr39 genes were found. The samples with the efficient genes Sr2 and Sr22 were included in crossings to create stem rust-resistant domestic varieties.
