Abstract The factors that affect the storage of the bulbs of the introduced tulip varieties (Tulipa L.) have been determined and the methods of their storage until autumn-spring in the conditions of the Right-Bank Forest-Steppe of Ukraine have been evaluated. For this purpose, a study of the storage conditions of 500 bulbs of 50 varieties of tulips of four groups (according to the flowering period) and their 15 classes (according to the modern Single classification system and data from the International Register of Tulip Names, adopted in the Netherlands in 1981) was carried out. Studies that have been carried out over two years (2020–2021) have shown that in order to get an abundant flowering of tulips, it is necessary to store planting material methodically correctly, paying special attention to the timing of digging out of the bulbs, sorting, drying and treating them with fungicides against diseases, selecting the right containers for storage in winter. It should be noted that the correct choice of a site for planting, timely application of organic and mineral fertilizers are also of great importance. The description of the condition of the tulip bulbs was carried out by the visual assessment method as a result of a thorough revision of each bulb of all varieties after digging them out, during drying, before planting in autumn, before laying them for winter storage and planting in spring. Studies have shown that bulbs of the Darwinian hybrid class, simple early class, Triumph tulips class and simple late class were preserved best of all. 100 % preservation of planting material during winter of 2019–2020, summer 2020 and 2021 was observed in 42 varieties. The rest of the varieties had 1–2 bulbs, which were partially or completely damaged.
