Abstract According to the results of researches it is established that in the territory of Vinnytsia NAU genus Forsythia Vahl. represented by 5 species, the most common of them: Forsythia suspensa (Thunb.) Vahl (about 47%), Forsythia europaea Degen & Bald (23%), slightly less common such species as: Forsythia ovata Nakai (12%), Forsythia × intermedia (10%), Forsythia viridissima Lindl. (8%). It was investigated that in Vinnitsa conditions the highest acclimatization numbers are characterized by the species Forsythia suspensa (Thunb.) Vahl., Forsythia ovata Nakai (85 and 87 points, respectively), the lowest acclimatization number are characterized by Forsythia giraldiana (Thorsybia). Vahl, Forsythia suspensa «Decipiens» (Thunb.) Vahl. (72 points) and Forsythia viridissima Lindl. (70 points), respectively. As a result of our research, we have found that most plants have the highest ornamental Forsythia europaea Degen & Bald (score 29-32), with an average degree of ornamental characteristic of Forsythia suspensa (Thunb.) Vahl. (score 23), a relatively low decorative score of the forsythia hanging in the conditions of VNAU biostationary was caused by spring frosts, as a result of which one- and two-year shoots of the plant were affected, which in turn negatively affected the flowering intensity of the species. As a result of these observations, we have identified groups of prospects for species of the genus Forsythia Vahl. in the conditions of the biostationary of VNAU. For perspective species we have included such as the forsythia Giralda and the forsythia average with a prospect score of 82 and 78, respectively. The plants of this group bloom and fruit annually, but are slightly less winter-hardy than the plants of the first group to which the forsythia hung and forsythia european ones belong.
