The article presents the results of a comprehensive introduction study of 18 cultivars of tubular narcissus from the collection of the Cheboksary Branch of the MBG RAS in 2016-2022 in order to select cultivars of value for production. The study of narcissus cultivars was carried out according to the classical methods of the Main Botanical Garden of the Russian Academy of Sciences. The assessment of decorative and economic and biological features on a 150-point scale in the soil and climatic conditions of the Middle Volga region was carried out. The potential possibilities of cultivars for use in green construction are investigated. In the comparative assessment, the main attention was paid to the decorative qualities of cultivars and their general adaptability to local conditions. The studied cultivars are divided into groups according to the flowering period. 8 cultivars of tubular narcissus bloom early (19.IV-2.V), 10 cultivars – in the middle (30.IV-11.V). The total flowering period is 30 days. The duration of flowering of introductions varies from 7-12 days (in the ‘Stentor’ cultivar) to 17-21 days (the ‘Arctic Gold’ cultivar). The decorative qualities of the cultivars were determined by the following indicators: aroma, originality, plant condition, duration and productivity of flowering, strength and length of the peduncle, size, color, shape of the flower. Assessment of tubular narcissus on a 100-point scale revealed a high degree of decorativeness in 8 cultivars with a total score of at least 90: ‘Soiree’ (92 points), ‘White Triumphator’ (93), ‘Point Barrow’ (94), ‘Grape Fruit’ (94), ‘Mount Hood’ (97), ‘Dutch Master’ (97), ‘Spellbinder’ (98), ‘Beersheba’ (98). When studying the economic and biological qualities of cultivars, the reproduction coefficient, damage by diseases and pests, general resistance to adverse conditions were taken into account. According to the methodology, the maximum score for economic and biological characteristics is 50 points. 15 collectible cultivars received high marks – in total more than 40 points. According to the complex of decorative and economic and biological features, the most valuable cultivars for introduction into the zonal assortment are cultivars with complex ratings of at least 140 points: ‘Beersheba’, ‘ Dutch Master’, ‘Grape Fruit’, ‘Mount Hood’, ‘Point Barrow’, ‘Soiree’, ‘Spellbinder’, ‘White Triumphator’. These promising, decorative, with high adaptive potential cultivars of tubular narcissus are recommended for industrial cultivation and landscaping in the conditions of the Middle Volga region.
