Abstract
In the Nikitsky Botanical Gardens (NBG), located on the southern coast of the Crimea (SCC), the genetic resources of eight flower and ornamental crops are collected, with which breeding research is conducted.
The total volume of these collections is 2718 species, cultivars, and forms.
A long-term study has revealed valuable features in several crops, which are most clearly manifested in the xerothermal conditions of the subtropical Mediterranean climate of the SCC. Modern cultivars of garden roses (Rosa × hybrida Hort.), whose origin includes subtropical species, have evergreen or semi-evergreen leaves and remontant, multiple flowering, the duration of which exceeds 200 days.
In Syringa L., early-blooming cultivars have the longest flowering period.
In Hemerocallis × hybrida Hort. particularly valuable features are the ability to remontant flowering and semi-evergreen and evergreen types of leaf growth inherited from Hemerocallis aurantiaca Baker., growing in subtropical-monsoon climate, and Iris × hybrida Hort.
NDASH ability to remontant flowering inherited from Iris lutescens Lam. native to the North-West of the Mediterranean.
The specified qualities of cultivars Hemerocallis × hybrida Hort. and Iris × hybrida Hort. allow us to significantly extend the period of decorative compositions with their participation under the conditions of the SCC. The introduction of evergreen and semi-evergreen species and forms of Clematis armandii Franch., C. montana Buch. – Ham. ex.
DC., C. montana var. rubens in landscape compositions contributes to the extension of the total flowering period of clematis by 30-35 days.
Cultivars of Canna × hybrida Hort. the most fully show their economic and valuable qualities under the conditions of the SCC: they have bright original flowers, ornamental foliage, the longest (up to 155 days) flowering and maximum height (up to 2.0 m for orchid-like and 1.5 m for the Crozy group cultivars). This allows us to fully use them in various landscape compositions.
Cultivars from the group of large-flowered chrysanthemums (Chrysanthemum × morifolium Ramat.) are suitable for cultivation in the open ground not only in flower design but also for cutting flowers.
The total volume of these collections is 2718 species, cultivars, and forms.
