Background. The article presents the data obtained after the screening of potato cultivars for resistance to Phytophthora infestans (Mont.) de Bary. The selected genotypes combine late blight resistance with other valuable commercial traits, such as high yield, high starch content, resistance to virus dis­eases and potato nematode (Globodera rostochiensis Woll.).Materials and methods. Potato accessions representing do­mestic and foreign cultivars from the VIR collection served as the material for this research. The screening was performed according to the techniques developed at the Potato Genetic Resources Department of VIR.Results and conclusion. The following true-breeding cultivars were identified for their re­sistance to Phytophthora infestans: ‘Ania’ (k-24063), ‘Baszta’ (k-24067), ‘Bobr’ (k-21103), ‘Dunajec’ (k-24074), ‘Klepa’ (k-24080), ‘Koga’ (k-24174), ‘Meduza’ (k-24082) and ’Mors’ (k-24083) from Poland; ‘Caprice’ (k-25193), ‘Certo’ (k-19440) and ‘Valetta’ (k-21769) from Germany; ‘Avrora’ (k-12188), ‘Bastion’ (k-25198), ‘Bryansky nadezhny’ (k-12160), ‘Vdokh­noveniye’ (k-12192), ‘Vektor’ (k-25200), ‘Velikan’ (k-25201), ‘Zvezdochka’ (к-25209), ‘Kalinka’ (k-25148), ‘Lukyanovsky’ (k-11750), ‘Musinsky’ (k-25312), ‘Nakra’ (k-11916), ‘Nikulin­sky’ (k-12171), ‘Prizer’ (k-25217), ‘Rapsodiya’ (k-25258), ‘Rossiyanka’ (k-12057), ‘Rucheyek’ (k-12213) and ‘Udacha’ (k-11900) from Russia; ‘Aktsent’ (k-12237), ‘Vetraz’ (k-11989), ‘Vytok’ (k-11897), ‘Zhuravinka’ (k-12106), ‘Kupalinka’ (k-12155), ‘Sintez’ (k-11666), ‘Suzorye’ (k-11992) from Be­larus; ‘Vikhola’ (k-11270), ‘Zarevo’ (k-10773), ‘Svitanok ki­evsky’ (k-11665), ‘Olviya’ (k-25094), ‘Rakurs’ (k-25098) from Ukraine; ‘Aytmurat’ (k-25248), ‘Berkut’ (k-25250), ‘Zholbarys’ (k-25155), ‘Nur-Alem’ (k-25253), ‘Senim’ (k-25306), ‘Sey­anets Lapteva’ (k-25161), ‘Sunkar’ (k-25258), ‘Tamyz’ (k-25307) and ‘Udovitsky’ (k-25260) from Kazakhstan; etc. High percentage of plantlets resistant to late blight was ob­served among self-pollination progenies of cvs. ‘Avrora’ (k-12188), ‘Astra’ (k-10697), ‘Vikhola’ (k-11270), ‘Zhuravinka’ (k-12106), ‘Nayada’ (k-12157), ‘Rosinka’ (k-11993), ‘Skarb’ (k-11904), ‘Bobr‘ (k-21103) and ‘Clarissa’ (k-21770). There were cultivars combining late blight resistance with such traits as resistance to potato nematode (Globodera rosto­chiensis Woll.) and viruses, high productivity, and increased starch content: ‘Zhuravinka’, ‘Ania’, ‘Baszta’, ‘Bobr’, ‘Certo’ and ‘Mors’. The selected genotypes are recommended as promis­ing to be included in potato breeding programs.
