The results of the evaluation of the viability of 20 in-troducents of the family Rosaceae Juss. from Siberian State University named after academician M.F. Reshetnev (SibSU) arboretum's collection are presented. SibSU arboretum is located in suburban area of Krasnoyarsk city and belongs, according to floral zoning, to the Anga-ra-Sayansky district of the Central Siberian province. The researches were carried out according to the meth-od developed in the Department of Dendrology of the Main Botanical Garden. According to the area of natural distribution species are conditionally divided into three groups (floras). The final assessment of the indicators for taxa was determined by the average long-term data prevailing in a biogroup. Winter hardiness, features of vegetative and generative development, the possibility of reproduction of taxa were established. The group of perspective species introductions for these conditions was determined, basing on the set of indicators. Stable and adapted biotypes were identified. The most per-spective and promising species were the species of the Far Eastern flora: Cerasustomentosa, Padusmaackii, Prunusussuriensis, Pyrusussuriensis, Sorbariasorbifolia, Crataegus chlorosarca, Prinsepia sinensis, Rosa ru-gosa; European species: Malus sylvestris, Sorbus aucuparia, Rosa glauca; North American species: Ame-lanchier alnofolia, Aronia melanocarpa, Padus pensyl-vanica, Padus virginiana, Physocarpus opulifolius. Less promising species were Armeniaca mandshurica, Amygdalus nana, Prunus spinosa which were recom-mended for cultivation with the application of methods of active acclimatization. Clear dependence of the viability of plants on their floristic distribution was not revealed. It is advisable to use allocated taxa (taking into account ecological characteristics) as part of additional range of landscaping. Further studies are aimed at assessing species that have passed acclimatization as a selection basis for fruit growing.
