The purpose of the research is to identify the most large-fruited and high-yield varieties of strawberry for breeding, commercial and amateur gardening. The work was carried out in the department of the “M.A. Lisavenko Research Institute of Horticulture for Siberia” according to the generally accepted methods. Yield accounting was conducted in 2016-2017 in comparison with the average long-term data. The objects of study were 7 early ripening strawberry varieties (control variety Darenka) and 12 mid- and mid-late-ripening varieties (control variety Pervoclassnitsa). From early ripening varieties on large fruitfulness, the variety Festival Romashka (maximum mass of berries was 36.2 g) was selected, from mid- and mid-late ripening varieties - Anastasia (38.5 g), Zabelinskaya (44.0 g), Pervoclassnitsa (48.4 g), Solnechnaya Polyanka (49.0 g). The average yield of strawberry according to the average long-term data was 2.7-20.9 t/ha, for 2016-2017 - 2.7-31.7 t/ha. Samples for the assortment expansion in commercial and amateur gardening were selected. For use in breeding, the following varieties were selected as sources: large fruitfulness - Pervoclassnitsa; high yield - 188 Zabelinskaya, Pervoclassnitsa, Solnechnaya polayanka; early ripeness - Festival romashka; high quality of berries (leveling by harvesting, density, transportability) - The Bylinnaya, Festival romashka; simultaneous ripening of berries - Spasskaya and Festival romashka.
