Purpose. To find out the ecological importance of winter triticale varieties in the formation of species diversity of agro-ecosystems. Methods. Field, laboratoryones and mathematical and statistical analysis. Results. The authors studied ecological importance of winter triticale varieties of forest-steppe and Polissia ecotopes as determinants of agrobiocenosis in the structural and functional organization of species diversity. It was found that less favourable ecological niche for pests-phytophags is such winter triticale varieties and lines as ‘Slavetne’, ‘AD 256’, ‘Chaian’, ‘DAU 5’, for epiphytoparasites – ‘Vivate Nosivske’, ‘Pshenychne’, ‘Slavetne polipshene’, ‘Slavetne’, ‘Yaguar’, respectively. It is determined that varieties and lines of winter triticale such as ‘AD 256’, ‘Vivate Nosivske’, ‘Pshenychne’, ‘Slavetne polipshene’, ‘Slavetne’ show high biological ability to compete with synanthropic vegetation and form distinct associations of segetal plants. Conclusions. It was found that agrophytocenoses of the studied varieties of winter triticale under the conditions of forest-steppe, Polissia-forest-steppe and Polissia ecotops determined in movements structural and functional organization of species diversity of agroecosystems.
