Abstract. A study of 413 spring oats collection samples from 42 countries was carried out. The aim was to determine valuable breeding varieties that demonstrate an optimal combination of the productivity and the duration of the ‘seedling – wax ripeness’ period. The work was carried out in the forest-steppe of the Ob River Region in 1994–2018. In terms of the duration of the ‘seedling – wax ripeness’ period, most varieties developed in Russian breeding institutions were given 4 and 5 points, while varieties from Western Europe, Estonia, Belarus and Ukraine received 3–5 points. OS 6 sample from India was given the lowest rating (1 point). Varieties from Turkey were evaluated at 2 points, compared to those from South America and China (3 points). Oats genotypes from Japan and Australia varied in the ranges of 3–6 and 4–5 points, respectively. Two varieties from New Zealand were rated at 7 points. The widest range of ratings, from 2 to 7 points, was noted for the genotypes from the USA and Canada. Over 25 years, an average positive (r = 0.39–0.61) correlation was established between the amount of precipitation by periods (May, May-July, May-August) and the hydrothermal coefficient (May-August) with the productivity of Krasnoobsky and Rovesnik standard varieties. High-yield varieties were identified by ripeness groups: very early – Neklan (Czech Republic), Dukat (Poland); early ripening – Carl Theodor (Germany), Ardo KR-FPTS (Czechoslovakia); middle-early – Uranus (Omsk Region), SG-K-93682 (Czech Republic), Magne (Sweden), Gramena (Germany), Allure (Ulyanovsk Region), LD 788 Poncho (France), David (Czechoslovakia), Klaus (France); mid-season – R8N9 3037-3072 (Krasnoyarsk Territory), Gallop (Moscow Region), Mutika 572 (Omsk Region), Kwant (Poland), AC Mustang (Canada), 55h 2106 (Moscow Region), OM 1385 (Great Britain); middle-late – Irtysh 22 (Omsk region), Rs-67 (Czech Republic); late-ripening – Mapua 70 (New Zealand), CDC Bell (Canada).
