| Abstract | The article presents the results of selection work on the creation of new varieties of chrysanthemums at the Pryluky Research Station of the Institute of Natural Sciences of the National Academy of Sciences of Ukraine. For this purpose, in 2009, the creation of a collection nursery was started, the basis of which was varietal material purchased from the NBS named after M. M. Grishko (Kyiv). Each year, the collection is replenished with new varieties, both domestic and foreign. In the first years of the study, attention was paid to the suitability of generative propagation of varieties by free pollination, with their subsequent use in selection to create source material. The features of the technology for growinghybrid chrysanthemum seedlings are described, in particular, cassette cultivation of seedlings, planting plants using a tape method, and the use of a fog tape for irrigation. Studies have shown that the implementation of the proposed method makes it possible to productively organize work on the care and evaluation of chrysanthemum samples at the initial stage of the selection process. After the initial selection, hybrid seedlings were propagated and studied, going through all stages from breeding, control to competitive nurseries. Based on the comprehensive assessment, four promising variety samples were identified: 11-27-11, 14-8-04, 17-10-16 and 17-12-08, which passed the State Variety Testing and are suitable for cultivation in the northern part of the Left Bank Forest-Steppe of Ukraine.Certificates of State Registration of Varieties were received in 2022 for Bagryana Osinh, in 2023 for Prometheus, Koralovo Namysto and Rozheva Diadema. These chrysanthemum varieties are characterized by high decorativeness, winter hardiness, resistance to diseases, pests and adverse environmental conditions. They have a high reproduction coefficient. Suitable for use in green construction to create group and solitary plantings, as well as cutting. Zonal recommendations: Forest-steppe and Steppe. | ||
