Abstract
The collection of eight ornamental plants in the Nikita Botanical Gardens (garden roses, irises, daylilies, tulips, lilacs, cannas, clematis, and chrysanthemum) account for 2,456 species, cultivars, and forms.
The collections renewal is carried out by introduction, and also by creating new domestic cultivars.
A wide range of morphological and biological characteristics qualitative variability within the species or the genus in each is represented by the time being.
The collections cultivars belong to different groups according to their ornamental and biological characteristics: coloring, doubling, a flower form, flowering duration, flowering term.
The cultivars, which have been introduced over the last years, are obtained through the process of introductive testing and are bred to put in the collections.
As the result of the introductive work, the collections biodiversity has been expanded constantly.
For the time being, the study of the new cultivars for the garden groups hybrids Hulthemia, spray roses, patio roses, the group of English roses cultivars by D. Austins introduction, Atragene, Flammula, Tangutica, Texensis clematis groups and Veridiflora tulips garden class is being done.
The cultivars with the new characteristics are prepared to be put in the collection: polypetalous lilac cultivars, garden roses cultivars with a coffee and blue coloring, with carved edges of petals, daylilies with a spider flower form, hybrid irises with a spatial continuation of a beard that looks like a horn and a petaloid, chrysanthemum cultivar with a filiform spider narrow-tubular inflorescence form, garden cannas with a dark-violet almost black flower coloring.
These cultivars are the sources of the new valued biological characteristics for the breeding work to create the perspective domestic cultivars in the conditions of southern Russia.
