Abstract
Seven species of three genera of perennial grasses for lawn agrophytocenoses on ashen-gray soils in a taiga zone were studied for the first time. The objective of the study was to identify the best samples of lawn grasses that can effectively use the agro-resource potential of natural climatic conditions of the research area. The width of a leave (texture) was used as one of the main indicators for the assessment of the decorativeness of a lawn grass stand. The samples were studied according to the methodological instructions of the All-Russian Williams Fodder Research Institute. Samples distinguished by grass stand high decorativeness were identified. Samples of meadow grass, bent grass and fescue grass, a variety of English bluegrass Yuventus are distinguished by complete winter hardiness. The lowest samples of meadow grass were varieties Yaskia, Limonsine, Barkenta; English bluegrass - Sport, Fiesta, Yuventus; bent grass - wild populations K-14272, K-14273, K-14265. Samples of English bluegrass - Yuventus, Primevere, K-14233 - are distinguished by the highest decorativeness of the grass stand in terms of the texture.

Summary
Ключевые слова: коллекционный питомник, мятлик, райграс, полевица, зимостойкость, морфологические признаки, декоративность, текстура листьев. Впервые изучались 7 видов 3 родов многолетних злаковых трав для газонных агрофитоценозов на подзолистых почвах в таежной зоне. Цель исследований – выделение лучших образцов газонных трав, способных эффективно использовать агроресурсный потенциал природно-климатических условий района исследований. Как один из основных показателей оценки декоративности газонного травостоя использовалась ширина листа (текстура). В результате выделены образцы с высокими показателями декоративности травостоя. Лучшей зимостойкостью отличались образцы мятлика, полевицы и овсяницы, сорт райграса пастбищного Yuventus. Самыми низкорослыми образцами мятлика лугового были сорта Yaskia, Limonsine, Barkenta; райграса пастбищного – Sport, Fiesta, Yuventus; полевицы – дикорастущие популяции К-14272, К-14273, К-14265. Самые высокие показатели декоративности травостоя по текстуре отмечены у образцов райграса пастбищного: Yuventus, Primevere, К-14233.
