THE RESULTS OF THE STUDY OF MULTIFLOWERED DAFFODILS IN FRC SSC OF RAS

Daffodil (Narcissus L.) is one of the leading bulbous crops from the Amaryllis family (Amaryllidaceae Jaume Saint-Hilaire), with an early spring flowering period. Selection works with this crop are carried out in many countries of the world, the leaders in the breeding of new cultivars and in the production of planting material are companies from the USA, Great Britain and the Netherlands. For the convenience and systematization of daffodils, an international classification has been developed, which includes 13 garden groups. The genetic collection of daffodils has been maintained and studied at the FRC SSC of RAS since 1961. The purpose of this work was to study and isolate new, introduced multi-flowered daffodils from various garden groups. The research was carried out at the Centre’s experimental sites in Razdolnoye village in 2018–2022. The cultivar study was carried out according to the methods of studying flower crops. 14 multi-flowered daffodil cultivars from various garden groups were studied: Double, Triandrus, Jonquilla, Tazetta, Poeticus, and daffodils distinguished solely by botanical name. As a result of the conducted research, it was found that in the humid subtropics of Russia, two studied cultivars begin growing in November, four – in December, five – in January, three – in February. The multiflowered cultivars from the Center's collection differ in terms of flowering dates and are divided into groups: very early – two cultivars, early – two, medium – four, late – six. In height, they belong to miniature – two cultivars, lowgrown– eight and medium-grown – four. Most have an average (from 1.6 to 2.5) and a high (2.6 or more) reproduction rate. The described cultivars can be used in landscaping, pot culture, for cutting and during forcing.
