Adaptive capacity of different potato varieties under the conditions of the Right-Bank Polissia of Ukraine

Purpose. To carry out an analysis of the ecological plasticity and stability of the characteristics of productivity, starch content, dry matter and to determine the parameters of ecological adaptability of potato varieties based on the characteristic “yield” in the soil-climatic zones of the Forest-Steppe and Polissia. Methods. The following methods were used in the research: laboratory, computational and statistical; to draw conclusions – analysis and synthesis. Results. The results of the analysis of potato varieties grown in different soil and climatic zones of Ukraine in terms of yield, starch and dry matter content are given. Promising varieties for selection and practical use with high indicators of adaptability, stability and plasticity were identified. It was found that the highest productivity results were obtained for the variety ‘RANOMI’ in the Forest-Steppe and Polissia zones – 34.6; 28.2 t/ha and high adaptability potential – 1.28; 1.27. The varieties ‘RANOMI’, ‘Cherie’ performed best in the Forest-Steppe zone with yields of 34.6 and 31.4 t/ha, in Polissia conditions – the varieties ‘RANOMI’, ‘PARADISO’ – 28.2 and 27.4 t/ha. The varieties with high plasticity were distinguished by starch and dry matter content (‘7 FOUR 7’, ‘PARADISO’, ‘FONTANE’, ‘RANOMI’, ‘LAUDINE’), productivity (‘7 FOUR 7’, ‘Rodriga’, ‘ALOUETTE’, ‘PARADISO’, ‘LAUDINE’). The varieties ‘Mysteriia’, ‘7 FOUR 7’, ‘LAUDINE’, ‘FONTANE’ and ‘LAUDINE’ proved to be very stable in terms of productivity and the varieties ‘Mysteriia’, ‘7 FOUR 7’, ‘Rodriga’, ‘PARADISO’, ‘RANOMI’ in terms of dry matter and starch content. The varieties with the highest productivity were ‘Rodriga’, ‘PARADISO’, and for dry matter and starch content – ‘FONTANE’, ‘LAUDINE’. Conclusions. In different soil and climatic zones, highly plastic varieties were selected according to yield index – ‘7 FOUR 7’, ‘Rodriga’, ‘ALOUETTE’, ‘PARADISO’, ‘LAUDINE’, according to starch and dry matter content – varieties ‘7 FOR 7’, ‘PARADISO’, ‘FONTANE’, ‘RANOMI’, ‘LAUDINE’. It was found that on average for 2019–2020 the highest productivity and high adaptive potential in the Forest-Steppe and Polissia zones had the variety ‘RANOMI’ – 34.6; 28.2 t/ha, respectively, CA – 1.28; 1.27. In the Forest-Steppe zone it is worth mentioning the varieties ‘Cherie’, ‘Rodriga’ with average CA index 1.15; 1.12 and productivity – 31.4; 30.62 t/ha, in the Polissia zone – ‘PARADISO’, ‘Rodriga’ with CA value – 1.20; 1.11 and productivity – 27.4; 25.5 t/ha.

An overview of bacterial causative agents of soft (wet) rot of potatoes is given, the epidemiological and etiological aspects of the diseases caused by them are analyzed. When preparing the article, general scientific methods were used: generalization, comparison, system analysis. Data from the European and Mediterranean Plant Protection Organization (EOPO), as well as data from phytosanitary services of EU countries and Ukraine, scientific literature served as material for the analytical study. Trade in plant materials, including potato seed tubers and ornamental plants, is largely responsible for the widespread distribution of pathogens. Locally, pathogens are also spread through plant debris, soil, waterways, aerosols, alternative hosts, and/or farm machinery. The main causative agents of bacterial wet rot of potatoes are gram-negative bacteria of the genera Pectobacterium and Dickeya and quarantine phytopathogens of the genera Clavibacter and Ralstonia. The main methods of detection and identification in asymptomatic potato tubers on an industrial scale are: phytopathological (visual examination of plantations and registration of symptoms of soft rot), microbiological (cultural-morphological and biochemical method, use of test systems for accelerated identification of microorganisms), immunoenzymatic ( enzyme immunosorbent assay), molecular genetic (PCR with specific primers, BIOLOG, DNA fingerprinting and nucleotide sequencing). To date, there are no completely effective pesticides to control all pathogens, so disease control measures will continue to rely primarily on avoiding infection during plant cultivation, and especially during the production of healthy certified seed. For a crop like potatoes, this is primarily based on obtaining bacteria-free minibulbs, applying strict seed certification schemes and strict phytosanitary restrictions. Knowledge of the sources of pathogens and routes of infection should be the basis for the application of phytosanitary measures, especially during and after harvest. Control of quarantine phytopathogens requires special attention. Soft rot pathogens are the main cause of limiting potato production in many regions of the world, particularly Clavibacter michiganensis subsp. sepedonicum and R. solanacearum are quarantine objects of the A-2 list of the European and Mediterranean Organization for Quarantine and Plant Protection. Upon entering our country, R. solanacearum has a high probability of acclimatization and spread in the country.
