The article presents results on winter and spring triticale breeding material developed at the Yuriev Plant Production Institute of NAAS of Ukraine. The purpose of the study was to develop complex-valuable lines of spring and winter triticale characterized by easy threshability and increased yield capacity. In 2024–2025, winter and spring triticale breeding material was investigated, and economically valuable, easily threshable lines with were identified. Seven spring triticale lines – ‘YaTKh 37-25’, ‘YaTKh 92-25’, ‘YaTKh 157-25’, ‘YaTKh 159-25’, ‘YaTKh 174-25’, ‘YaTKh 179-25’, and ‘YaTKh 183-25’ – as well as four winter triticale lines – ‘TKhZ 168-25’, ‘TKhZ 194-25’, ‘TKhZ 215-25’, and ‘TKhZ 216-25’ – with easy threshability significantly outperform the chek cultivar, 'Volia Kharkivska', and the best reference cultivars, 'Svoboda Kharkivska' and 'IR Lehit' in terms of yield and specific valuable economic traits, including grain size and plumpness, starch and protein contents, kernel hardness, etc. Technological analysis of the lines demonstrated that the overall bread-making scores of the selected spring and winter triticale lines were quite high (7.8–8.6 points). Pedigree analysis showed that the lines were developed through intraspecific hybridization involving parental components with the “easy threshability” and “high yield capacity” traits. These lines are promising source materials for triticale breeding.
