Abstract. The article presents the results of perennial (2010‒2017) complex studies of the genus Poaceae Barnhart species collection in the Botanical Garden of the Institute of Biology, Komi Scientific Center, Ural branch of RAS, which are included 41 species (53 samples) belonging to 20 maternity. Perspective ornamental cereals of 12 species of 9 genera were bred (Beckmannia Host, Briza L., Bromopsis Fourr., Dactylis L., Deschampsia Beauv, Elymus L., Festuca L., Melica L., Phleum L.). They can be used in green building in the northern region. The species` prospects were determined by indicators, which are important during a growing plants in the North: winter hardiness; the passage of all development phases during the growing season; the ability to form fertile seeds; high decorative qualities. All species differ significantly in terms of their reproductive ability, as evidenced by data on real seed productivity (RSP) (pcs/m2 ) and laboratory seed germination (%).The maximum indicators of these signs are noted for the Phleum pretense and Briza media plants. Briza media (80 %), Melica nutans (71 %) and Deschampsia caespitosa (68 %) are notable for their high seed germination, except Phleum pratense (100 %). Plants of species of the genus Festuca are characterized by the lowest indices of these characters. It was found that the optimal time when using promising species in landscaping is the 2 and 3 years of life. After that, they should be reseeded due to loss or decorative properties: thinning the grass stand during the wintering process, disturbing the uniformity of the coverage of the occupied area, reducing the number of generative shoots.
Keywords: introduction, grass plants, Poaceae family, ornamental use, winter hardiness, seed productivity.
