Potato varieties resistance study to wart Synchytrium endobioticum (Schilbersky) Percival and late blight Phytophthora infenstans (Mont) de Bary
2023
The results of research on the selection of potato varieties and breeding material from Institute for potato study NAAS and Institute of Agriculture of Carpathian Region NAAS are presented in this paper. There were selected 12 potato varieties of Ukrainian breeding with high resistance level: ‘Aria’, ‘Glazurna’, ‘Knyagynya’, ‘Zheran’, ‘Zhytnytsia’, ‘Podolyanka’, ‘Skarbnytsia’, ‘Slavyanka’, ‘Chervona Ruta’, ‘Fantasy’, ‘Schedryk’ and ‘Chortytsia’ (1.2–2.4 points (R1) and 2 varieties (‘Dyvo’ and ‘Povin’ - 3.4 and 3.0 points (R2)) by the research results for potato assessment to wart in 2020–2021 by the results of field and laboratory studies for determining Ukrainian breeding potato varieties resistance to wart Synchytrium endobioticum (Schilb) Perc. There were chosen 6 varieties with relatively high resistance degree to late blight Phytophthora infenstans (Mont) de Bary (7.2–8.5 points): ‘Aria’, ‘Dyvo’, ‘Zhytnytsia’, ‘Knyagynia’, ‘Podolyanka’ and ‘Slavyanka’ by the choice. The evaluation results allow to put them into the State Register of plant varieties suitable for dissemination in Ukraine. These potato varieties recommend for implementation in potato disease sources and usage as a parent form for crossing as sources of potato resistance to wart and late blight.
