Historical varieties in the rose collection of the Central Botanical Garden of the National Academy of Sciences of Belarus

The article contains the information about 29 historical varieties of roses cultivated in the Central Botanical Garden of the National Academy of Sciences of Belarus for more than 50–70 years. They belong to 5 garden groups, including the oldest roses – repairable ones. The plants were described and the morphometric indicators and features of flowering plants in the garden were established. Winter hardiness of varieties in local conditions was estimated. It is noted that such varieties should be preserved in collections, because they not only reflect the history of rose breeding, but also are a valuable gene pool for breeding work.
