The article presents the results of breeding research with representatives of the peony genus complex (Paeonia L.) at the South Ural Botanical Garden-Institute of the Ufa Federal Research Center of the Russian Academy of Sciences. The study aims to create highly ornamental cultivars of hybrid peony (P. hybrida hort.) for the climatic zone of the Republic of Bashkortostan. The cultivars are characterized by high resistance to diseases and pests, as well as by winter hardiness and heat tolerance. Since the 1950s of the 20th century, a collection fund of the Paeonia genus complex has been formed in the Ufa botanical garden. This enabled selection of parental forms with specified ornamental traits for hybridization. In 1999-2000, the garden staff conducted crossing combinations between certain peony cultivars. Also, they collected seeds from open pollination. As a result of sowing the obtained seeds outdoors, about 200 seedlings from controlled pollination and 22 from open pollination were grown. When the hybrids reached the reproductive period of development, they were carefully selected according to the main ornamental traits (color, doubleness, flower size). Specimens superior to the parental cultivars or especially noticeable for one such trait were selected. Upon reaching the period of full and mass flowering, the selected hybrids were evaluated according to the methodology of the State Variety Test of the Russian Federation. Of these, 11 promising hybrid seedlings distinguished by their ornamental features were selected for transfer to the State Variety Site for plant breeding testing. The article describes new hybrid peony cultivars (‘Bashkirskaya Zhemchuzhinka’, ‘Bashkirskiy Suvenir’, ‘Geliya’, ‘Kruzhevo Sada’, ‘Minzifa’, ‘Pamyati A.S. Sakharovoy’, ‘Ural’skaya Fantaziya’, ‘Ufimskiy Val’s’, ‘Ufimskiy Rassvet’, ‘Yubileynyy YuUBSI’, ‘Yantarnoye Ozherel’ye’) included in the State Register. All cultivars bred in the botanical garden are resistant to adverse weather conditions, pests, and diseases. Moreover, they are winter-hardy and drought tolerant. We recommend including them in the assortment of cultivated plants used for soft landscaping in the populated areas of Bashkortostan and generally in central Russia.
