Abstract. The purpose of the studies was to give a comparative assessment of the collection forms of potato from the Netherlands, Germany, Belarus, and Russia by yield and biochemical indicators of tubers under conditions of the Middle Urals to identify the sources of these traits in directed breeding. The sample included 15 varieties from each country. The work was performed in 2017–2019. The varieties of different breeding schools differed slightly in the main economically useful characteristics. For three years of the study, the average yield for the countries was at the level of 30.3–34.1 t/ha, with a variation coefficient of 16.4–22.2%. The most high-yielding varieties from the Netherlands were Arizona (41.8 t/ha), Colomba (40.7 t/ha), Aluet (40.0 t/ha); the most high-yielding variety from Germany was Queen Anne (40.8 t/ha); the most high-yielding varieties from Russia were Lyuks (42.3 t/ha) and Meteor (40.7 t/ha). Especially valuable varieties combining high productivity with low variability of traits from the Netherlands were Aluet (40.0 t/ha; 6.8%) and Red Scarlett (34.0 t/ha; 2.0%); from Germany – Gala (31.4 t/ha; 6.5%), Inara (36.6 t/ha; 6.7%), Ricarda (37.7 t/ha; 8.1%); from Belarus – Nara (38.1 t/ha; 10.1%), Yanka (32.6 t/ha; 0.2%); Russia – Velikan (33.9 t/ha; 10.3%), Gornyak (35.0 t/ha; 4.0%), Lyubava (38.2 t/ha; 4.9%), and Lyuks ( 42.3 t/ha; 5.5%). The highest content of starch was noted in the varieties from Belarus, it was on average 13.0%. Differences between groups of different origin in terms of protein, sugars, vitamin C, and nitrates were insignificant. We identified varieties with a set of traits that combine value both as source material for breeding and for cultivation for production purposes: Aluet, Colomba, Madeleine (Netherlands); Gala, Inara, Queen Anne, Mia (Germany); Nara, Karsan, Charodnik, Yanka (Belarus); Gornyak, Lyuks, Lyubava, Meteor (Russia).
Keywords: potato (Solanum tuberosum); variety; genotype; source material; yield; biochemical parameters.
