Complex assessment of Hemerocallis hybrida Hort. cultivars under the conditions of the Forest-Steppe Zone of the Bashkir Cis-Urals

A comprehensive assessment and selection of the most valuable taxa suitable for use in landscaping under certain natural and climatic conditions is one of the most important tasks of introduction studies of ornamental plants. The article presents the results of a comprehensive variety assessment, a study of the seasonal rhythm of growth and development, and morphometric characteristics of 20 hybrid daylily varieties (Hemerocallis hybrida hort.) in the South-Ural Botanical Garden-Institute of UFRC RAS. An assessment of the decorative and economically valuable qualities of daylily varieties was given on a 100-point scale, including 11 traits: color, size and shape of a flower, plant habitus, height of the flower stalk, abundance of flowering, originality, reproductive ability, duration of flowering, sustainability in unfavorable conditions, resistance to diseases and pests. As a result of our variety assessment of Hemerocallis hybrida hort., the entire studied assortment was divided into 3 groups according to the prospects for use in decorative floriculture. 8 highly promising varieties (‘Bela Lugosi’, ‘Bestseller’, ‘El Desperado’, ‘Ledgewoods Jumstar’, ‘Moon Over Monteray’, ‘Pardon Me’, ‘Red Rum’, ‘Stella de Oro’) have been identified for cultivation under conditions of Bashkortostan Republic. They are distinguished by their bright color and original flower shape, abundant and long flowering, strong peduncle, and high reproductive capacity. Nine varieties are characterized by medium prospects (‘Artic Snow’, ‘Cherry Eyed Pumpkin’, ‘Final Touch’, ‘Frans Hals’, ‘Macbeth’, ‘Mini Stella’, ‘Pandoras Box’, ‘Sea of Cortez’, ‘Tooth’); 3 − are unpromising (‘Night Embers’, ‘Prince of Lemon’, ‘Strawberry Candy’). All studied varieties can be used in various types of flower decoration under the conditions of the Bashkir Cis-Urals.
