Introduction and breeding research has been carried out in garden roses in the Nikita Botanical Gardens since 1812. More than 6,000 species, cultivars and forms of roses have been studied. Thirty groups out of 36 existing garden groups of a world garden rose assortment were utilized by the scientists of the Nikita Botanical Gardens in the breeding research. The analysis of usefulness of different garden rose groups for the conditions of a dry subtropical zone of the south of Russia has been done. More than 300 domestic cultivars out of nine most perspective garden groups have been created: Hybrid Tea, Grandiflora, Floribunda, Polyantha, Miniature, Schrub, Ground Cover Plants, Large Flowered Climber, Kordesii. While creating the domestic cultivars, different breeding methods like analytic and synthetic breeding: an individual selection, cross-pollination, inbreeding, an inter-variety and distant hybridization, radiation and chemical mutagenesis. The most effective methods of breeding have been discovered an inter-variety and distant hybridization, and experimental mutagenesis. These methods underline the complex garden rose breeding system that was used, which had been worked out at the Nikita Botanical Gardens.
