Abstract. Hemerocallis hybrida hort. is a decorative perennial short–rooted polycarpic of the red-leaf family (Hemerocallidaceae R. Br.), genus (Hemerocallis L.). Daylily (krasodnev) is widely known as a summer-flowering, sustainable crop, which is still insufficiently used in the green construction of the Novosibirsk region. This is due to the lack of recommended assortment from different garden groups adapted to the sharply continental climate of Western Siberia. The aim of the study was to evaluate the varieties of hybrid daylily from the collection of the Central Siberian Botanical Garden according to the complex of decorative and economic features for rational use in the floriculture of Siberia. Methods. In accordance with the methodology of V. N. Bylov et al. the introduced varieties were evaluated for decorative features (plant height, inflorescences, bush habitus, flower color and size, number of flowers in the inflorescence, aroma) and economic and biological properties (timing and duration of flowering; number of vegetative and generative shoots, resistance to weather factors, diseases and pests). Results. As a result of morphobiological analysis of 90 varieties of hybrid daylily, varieties from different garden groups were identified that have a score of 63–99 points for decorative qualities (Angel of Light, Christopher Columbus, Pandora, s Box, White Cream, Strawbary Candy, Primel Seream, Red of Roses, Lady Hesketh, etc.). According to the economic and biological properties of the variety estimated at 27–48 points. As a result of a comprehensive 150-point assessment, 52 varieties were identified as very promising (more than 120 points), 30 varieties are promising (106–120 points), 8 unpromising varieties (less than 105 points), these are Lemon Bells, Goi, Revolute, Awaited Hourse, Highland Lord, Close Childe, Apricot, Solid Scarlet. Scientific novelty. For the first time, a ranking of 90 varieties of hybrid daylily introduced into the conditions of the forest-steppe zone was carried out and a sorting was recommended for different types of plantings (mono- and mixed groups, mixborders, rabatki, borders, tapeworms, containers).
Keywords: daylily, varieties, biological features, decorative and economic features, rational use, forest-steppe zone, Western Siberia.
