Assessment of decorative features of representatives of the genus narcissus l. in the South-Ural botanical garden-institute of UFRC RAS

Abstract

The article presents the results of the primary introduction study of nine new varieties of the genus Narcissus L. (‘Apricot Whirl’, ‘Candy Princess’, ‘Green Eyes’, ‘Mon Cheri’, ‘Peach Cobbler’, ‘Slim Whitman’, ‘Sunlover’, ‘Sunny Girlfriend’, ‘Sunny Side Up’) on the basis of the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of Russian Academy of Sciences. It is shown that more than half of these cultivars from the SUBGI UFRC RAS collection are represented by plants registered in the last century. According to the international classification, introduced species were assigned to four groups. The maximum number of varieties is presented in groups: large-crowned narcissus and narcissus with a split crown. It was revealed that in two years of study, all cultivars reached the flowering phase. The main biomorphological parameters of introduced varieties (plant height, leaf length and width, flower diameter, length and width of the crown and perianth lobes) were studied. It has been determined that most varieties are characterized by a two-tone color and an average flower size. Phenological observations were carried out. It was revealed that spring regrowth in all studied varieties is observed aft er snow melt in the second decade of April. By the timing of flowering, cultivars are divided into early (flowering in the III decade of April) and early middle (flowering in the I decade of May). The duration of the flowering phase varied on average from 6 to 12 days. The decorative qualities of the studied varieties have been investigated. On a 100-point scale, five cultivars scored over 90 points (‘Mon Cheri’, ‘Sunlover’, ‘Candy Princess’, ‘Apricot Whirl’, ‘Sunny Side Up’). They have large and beautifully shaped flowers, with a clean bright color of the perianth and crown, strong and tall peduncles, long and abundant flowering, pleasant aroma. These varieties are the most promising for inclusion in the zonal assortment of cultivated plants recommended for use in green building in the Republic of Bashkortostan.
