More than 280 species, genotypes and varieties of wood plants representing 31 families are grown in the arboretum at the Russian Research Institute for Fruit Crop Breeding. At present, the task of study and introduction of qualitatively new range of plants capable to grow in new constantly changing conditions is urgent. The analysis of ecological and biological features of 23 species of introduced plants of Rosaceae family of different ecological and geographical origin from the VNIISPK collection has been done. 10 highly ornamental genotypes resistant to a complex of unfavorable factors of the environment have been allocated for use in the greenbelt setting of the settlements in the Central Chernozem region of Russia including the Orel region. According to our data the Far East zone is the most perspective one for the introduction of wood plants of Rosaceae family. It includes 6 promising species (50% of the studied species of this zone): Cotoneaster lucidus, Cotoneaster divaricatus, Potentilla fruticose, Padus Maackii, Spirea gemmate and Spirea japonica.
