Abstract The evaluation of 50 introduced tulip genotypes (Tulipa (L.) in the conditions of the Right-Bank Forest-Steppe of Ukraine were made by the Department of Horticulture of Uman National University of Horticulture into groups, classes, where different varieties, mainly of foreign selection were represented according to their decorative qualities, basic economic and biological features and grouped into a collection. The indicators concerning the phonological phases of development of introduced plants in the context of individual varieties of tulips and on average by years of research carried out and generalized. A brief agrobiological and decorative characteristics of collection varieties in the conditions of the Right-Bank Forest-Steppe of Ukraine, which are included in further research on the cultivation and reproduction of promising varieties is given/ Bulbs of all introduced varieties were planted in late September, namely on the 25th-27th, so that they would be fully rooted. before the first frosts, It should be noted that first of all, small fractions of bulbs were planted, sticking them into the loose soil at the bottom of the furrow made only with a distance of 6–8 cm from each other. However, we also took into account the factor that small bulbs were planted somewhat denser at depth, which is usually three times the height of the bulb. The plant survival stage was completed within 2–3 weeks. For processing we have chosen a site in the botanical nursery of the Department of Horticulture, where there are no stagnant floods and rainwater. During its preparation, a large fraction of river sand was applied for better moisture throughput, and with a small excess it can be easily removed. Later, when the soil actually freezes to a small depth, namely 1–3 cm, the experimental area was mulched with 3–5 cm sawdust and in the spring the mulch was raked. The experimental area was completely protected from cold winds, which in turn didn’t shorten the flowering period and didn’t actually weaken the plants. Field observations on the resistance of different varieties of tulips to gray rot in the Forest-Steppe of Ukraine were carried out and it was found that the infection of the studied genotypes was at a low and very low level, despite the contrasting conditions of different years of study. In early spring seedlings were sprayed with fungicides to prevent gray rot.
