Issue №: 1 (40)
This issue of the journal is devoted to current issues related to the optimization of technological elements in the cultivation of agricultural crops. Considerable attention is paid to the specific features of growing vegetable and cereal crops, which play an important role in ensuring the state’s food security. The scientific publications present research results on the role of leguminous crops in improving soil fertility, the development of domestic and international adaptive breeding, as well as the application of mineral and foliar fertilization to increase the productivity of agroecosystems. Separate studies are devoted to improving the efficiency of forest management and to issues related to landscape greening.

The article presents the results of a long-term comprehensive assessment of the resistance of potato varieties and hybrids to Phytophthora infestans under the natural infectious background of the Carpathian region of Ukraine during 2023–2025. The study was conducted using breeding material of different genetic origin in order to establish patterns of resistance under contrasting hydrothermal conditions and to identify stable sources of resistance for practical breeding. It was found that the meteorological conditions of the years significantly influenced the intensity of late blight development and the nature of genotype differentiation. In 2023–2024, under conditions of increased moisture and moderate temperatures, forms with weak and medium resistance prevailed, while in 2025, under changed hydrothermal conditions, the proportion of resistant and highly resistant genotypes among hybrid material and varieties ranged from 45 to 89%. Analysis of the distribution of genotypes by resistance categories revealed statistically significant interannual and decadal differences (χ², p < 0.001), indicating pronounced epiphytotic pressure and high informativeness of the test site conditions. A ten-day analysis of average resistance scores identified the second ten days of August as a critical period for disease development, when the maximum decrease in resistance was observed. A strong positive correlation was found between the average hydrothermal coefficient of the growing season and the average resistance score of hybrids (r = 0.998; p < 0.05), confirming the decisive role of weather conditions in the realisation of genetic resistance potential. Based on the results of a long-term assessment, the following genotypes were selected: Z.15.96/4, P.17.30-3, P.15.5/27, P.17.19-26, P.17.20-3, P.17.38/16, P.18.78/1, Soborna, Helena and Rodinna, which maintained an increased level of resistance over two years under various scenarios of epiphytotic development, indicating a likely polygenic nature of resistance. The data obtained confirm the uniqueness of the Carpathian natural infectious background for objective selection evaluation of potatoes and scientifically based selection of sources of resistance to late blight.
