Abstract

The objective of research is to examine collection potato accessions and identify genotypes with a complex of economically valuable traits for use in breeding. The paper presents the results of a study of 71 potato accessions of domestic and foreign selection for economically valuable traits over the period 2022–2024 in the Kamchatka Region. The Fresko and Vulcan potato varieties were used as standards. The evaluation of the potato varieties resulted in the identification of early-ripening genotypes with high yields (over 50 t/ha): Zhavoronok, Meteor, Latona, and Fiesta; mid-early genotypes: Detskoselsky, Ryabinushka, Severyanin, Samba, Gala, and Evolution; and the mid-season variety Provento. The following varieties were selected domestically and had a marketability of over 90 %: Arktika, Zhavoronok, Pushkinets, Lileya Belorusskaya, Udacha, Irbitsky, and those of foreign selection: Raya, Provento,. The following early-ripening varieties were noted for their large-tuber capacity exceeding 91 g: Zhukovsky ranniy, Zhavoronok, Pushkinets, Udacha, Fiesta, Fermer; the following mid-early and mid-season varieties were noted: Zoya, Irbitsky, Ketsky, Ladozhsky, hybrid 134-2-2006 (VIR), Zekura, Raya. The following varieties were characterized by increased starch content in potato tubers (12.0–19.7%): Alyi Mestny, Vasilyok, Detskoselsky, Kamchatka, Ketsky, Lazar, Solnyshko, Severyanin, Mayak, Otrada, Memory of Rogachev, Adretta, Agata, Alvara, Zekura, Raya; interspecific hybrids: 8-1-2004, 99-6-6, 135-5-2005, 134-2-2006, 8-5-2004, 94-5 (VIR); increased content of vitamin C in tubers (7.9–16.0 mg%) were noted in the following early-ripening varieties: Zhemchuzhina Kamchatki, Apis, Fiesta, Varmas, Gala, hybrid 99-6-5 (VIR). Based on the results of evaluation of table qualities with slight darkening of the flesh of boiled tubers (7.0–8.0 points), the following early-ripening varieties were distinguished: Alena, Zhemchuzhina Kamchatki, Meteor, Penzenskaya Skorospelka; from mid-early and mid-season varieties: Vulcan, Agata, Detskoselsky, Otrada, Sante, Solnyshko, Severyanin, hybrid 12-13-90, Evolution. In the conditions of the Kamchatka Region, potato varieties with a complex of economically valuable traits — Alyi Mestny, Arktika, Vulcan, Zhemchuzhina Kamchatki, Zhavoronok, Zhukovsky Ranniy, Kolymsky, Meteor, Radonezhsky, Rucheyok, Severyanin, Solnyshko, Sirenevy Tuman, Kamchatka; Udacha, Charodey, clone 94-5, Alvara — are recommended for use in breeding as parental forms when creating new potato varieties.
