Purpose. Theoretical and experimental substantiation of introduction of “Romantica” roses originated by Meilland company under the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. Methods. Biometrical, comparative-morphological, statistic ones. Results. Viability, growth and development indices as well as ornamental qualities (tolerance for winter conditions, frost hardiness, drought resistance, complex disease and pest resistance, habit maintenance, shoot formation, flowering, coloration, shape of flowers, petal number etc.) were analyzed for 12 rose cultivars of “Romantica” series planted on the collection and exhibition plots of the National Dendrological Park «Sofiivka» NAS of Ukraine. The investigations were conducted within 2012–2015. The most of the cultivars got the mark of introduction success 41–45 points of 50; so, the cultivars are totally promising for introduction into the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. ‘Leonardo da Vinci’ and ‘Yves Piaget’ cultivars got point number 35–38 and they can be considered promising ones. The acclimatization number for the most of the investigated cultivars was 85–90 points of 100 that means good adaptation of the plants in the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. The adaptation of cv. ‘Leonardo da Vinci’ and cv. ‘Yves Piaget’ roses (point number 75) can be considered satisfactory. The total evaluation of “Romantica” roses ornamental qualities made 76–87 points of 100; so, all the cultivars display high ornamental qualities and deserve to be introduced to the production. Conclusions. The garden roses of “Romantica” series originated by Meilland company being introduced into the conditions of the Right-Bank Forest-Steppe Zone of Ukraine are adapted well in the introduction region and they are promising for the subsequent introduction.

The article unveils results and prospects for the introduction of lesser-known vegetable crops of Cucurbitaceous family to extend the diversity among vegetables. Among 5 species the best by commodity yield and quality indexes are selected. The promising species could be recommended for use in horticulture and landscaping. Introduction onto the territory of Ukraine of new lesserknown species of Cucurbitaceous family, such as trichosanthes, luffa, lagenaria, anguria, momordica will enable to extend the use of vegetable crops in landscaping for the designing of alpine hills, ornamental beds, decorating verandas, arbours, balconies with planting, as a wonderful material for artistic visage, restaurant business and agro-tourism. To extend the diversity among the vegetables in openair espalier growing it is promising to run the cultivation of disease and pest resistant, displaying good indices of taste estimate and quality species, namely trichosanthes of 5,1 kg/sq.m. commercial yield, with fresh and canned fruits accumulating high content of a dry matter (6,5 to 10,1%) and sugars (4,1 to 8,5%) and characterized by taste estimate for the processed foodstuff of 8,5 points.

Purpose. Studying and identifying winter wheat varieties that are resistant to causal agents of major diseases and pests. Methods. Laboratory analysis, field study. Results. On artificial infection backgrounds of causal agents such varieties as ‘Smuhlianka’, ‘Svitanok Myronivskyi’, ‘Berehynia Myronіvska’, ‘Horlytsia Myronіvska’ have shown high level of resistance to brown rust; ‘Svitanok Myronivskyi’, ‘Berehynia Myronіvska’ – to powdery mildew; ‘Smuhlianka’ – to covered smut. Varieties ‘Voloshkova’, ‘Yuviliar Myronivskyi’, ‘Myrliena’, ‘Oberih Myronivskyi’, ‘Kolos Myronivschyny’, ‘Lehenda Myronivska’ had medium resistance to Septoria leaf blotch; ‘Smuhlianka’, ‘Myrliena’, ‘Oberih Myronivskyi’, ‘Berehynia Myronіvska’, ‘Horlytsia Myronіvska’, ‘Myronivska storichna’ – to Fusarium head blight; ‘Myronіvska 65’, ‘Smuhlianka’, ‘Lehenda Myronivska’, ‘Berehynia Myronіvska’ – to root rots. Among the varieties studied, there were those with group resistance to diseases: ‘Voloshkova’, ‘Myrliena’, ‘Yuviliar Myronivskyi’, ‘Oberih Myronivskyi’, ‘Bohdana’, ‘Myronivska storichna’, ‘Ekonomka’, ‘Svitanok Myronivskyi’, ‘Berehynia Myronіvska’, ‘Horlytsia Myronіvska’, ‘Smuhlianka’. Varieties bred at the V. M. Remeslo Myronivka Institute of Wheat are distinguished by pest resistance. During autumn tillering phase of winter wheat the smallest number of large cereal aphids was observed in varieties ‘Smuhlianka’ and ‘Myronivska storichna’, leafhoppers – in varieties ‘Smuhlianka’, ‘Myrliena’, ‘Yuviliar Myronivskyi’. The slight population of thrips in the phase of earing was marked in the variety ‘Kolos Myronivschyny’, in the milk-ripe stage the smallest number of larvae per ear was detected in varieties ‘Smuhlianka’, ‘Voloshkova’, ‘Kolos Myronivschyny’. Varieties ‘Lehenda Myronivska’ and ‘Smuhlianka’ were proved to be resistant to damages of stems by sawflies. It should be noted that ‘Smuhlianka’ variety shows resistance to aphids, leafhoppers and grain sawflies. Conclusions. It was established that winter wheat varieties bred at the V. M. Remeslo Myronivka Instutite of Wheat are characterized by resistance to certain causal agents, some of them – to their group. Varieties that are resistant to the most common and harmful phytophages were identified.
