The results obtained during the study of resistance of promising gooseberry varieties to Septoria leaf spot in the Western Forest-Steppe of Ukraine are described. Variety samples were divided into groups by the resistance to disease. Among them none was found with complete field resistance. Sladkiy proved to be highly resistant variety. Resistance above the average is typical for Berill, Grushenka, Kooperator, Lehin, Malakhit, Rodnik, Shennon varieties. Hrossulyar, Kamenyar, Karat, Knyazhych, Kolobok, Krasnoslavyanskiy, Laskovyi, Mazershkota, Russkiy, Svityaz, Severnyi kapitan are varieties of average resistance to Septoria leaf spot. Zyelyonyi dozhd, Zlatogor, Invikta, Kubanyets, Nesluhivskyi, Slivovyi are characterized as low resistant ones.

The author presents the results of studying of black currant 9 varieties resistance against pathogenic fungi. The most resistant varieties against Sphaerotheka mors-uvae Berk, et Curt are Yarynka, Leleka and Pamyaty Leonyda Mycha- levskogo; against Septoria ribis Desm - Leleka and Govtva; against Cronartium ribicola Dietr - Yarynka, Dochka Vorskly and Govtva.

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.

The article features summary of studying the resistance of rasberry promising varieties to main diseases (Didymella applanata Sacc., Gloeosporium venetum Speg. і Septoria rubi Sacc.) of stem expression type under the conditions of the Ukraine’s Northern Forest-Steppe. 8 summer rippeing varirties (‛Gusar’, ‛Kryepysh’, ‛Novokytaivs’ka’ (control), ‛Perseya’, ‛Saya’, ‛Tarusa’, ‛Phenomen’) were asessed, as well as the same number of that remontant (‛Babye lyeto 2’, ‛Heracles’, ‛Zolotyye kupola’, ‛Lyulin’, ‛Nyedosyagayemaya’, ‛Osinnya’ (control), ‛Osinny zorepad’, ‛Polana’). Weather conditions of the 2009-2011 vegetation periods were described. Favorable conditions were determined for the above raspberry diseases development. The studied varieties were divided into groups of resistance to the studied diseases. The resistance of the overwhelming majority of varieties was average to above average. The ‛Patricia’ and ‛Novokytaivs’ka’ (control) displayed low resistance against Dydimella and septoria spot, respectively. The varieties of ‛Kryepysh’, ‛Saya’, ‛Tarusa’, ‛Polana’, ‛Niedosyagayemaya’ and ‛Osinnya’ (control) have been found to display a complex resistance to Dydimella, anthracnose and septoria spot under conditions of the region researched.
