The goal is agroecological and cluster analysis of winter triticale collection samples to identify sources of breeding traits. To expand and ensure the use of the genetic diversity of winter triticale in the conditions of the Western Polissia by establishing identification elements of the component system of valuable economic traits for culture samples with increased adaptive properties to the conditions of the region. In the conditions of Western Polissia, 105 samples of winter triticale were studied and the best 35 of them were introduced. The information database of winter triticale samples has been updated regarding economic and valuable and biological characteristics. A representative triticale collection was formed in the amount of 164 samples, of which 125 are winter and 39 are spring triticale. 116 samples have been deposited, 96 collection samples have been certified. 4 samples of winter triticale were transferred for long-term storage in the National Storage. Sources of valuable traits are identified: short stemness, early maturity, optimal plant height, long ear, grain fullness, resistance to brown leaf rust and leaf septoriosis. The samples were classified according to 36 morpho-biological and economic characteristics. According to valuable economic characteristics, reference samples were selected: Khleborob (RUS), Tit (RUS) - medium-early; Shalanda (UKR) – high level of winter hardiness, high density of stems, high level of productivity; Tit (RUS) – high level of regeneration intensity; Titus (RUS), Timofey (UKR) – high level of resistance to lodging; Maestro (POL) - high level of productivity; Rat (RUS) - high stem density; Pudik (UKR) - high resistance against the main pathogens.
