The purpose of the research is to create winter-hardy, large-fruited, high-yielding, high-quality varieties of apple trees of different ripening periods and their growing technology (use of a biological product) in the South Urals. The research was carried out on the basis of Orenburg Experimental Station of Horticulture and Viticulture - a branch of the Federal State Budgetary Scientific Institution “Federal Scientific Selection and Technology Center for Horticulture and Nursery ” from 1999 to 2020. Research objects were summer apple varieties – “Orenburgskoe”, “Orenburgskoe krasnoe”, “Solntsedar” (K); winter – “Orenburgskoe pozdnee”, “Zimnee”, “Yuzhnouralskoe” (K). The counts and observations were carried out according to generally accepted methods. As a result of the studies, the data obtained showed that the property of short stature as a genetic trait of resistance is transmitted to the offspring during hybridization. The varieties “Orenburgskoe pozdnee”, “Zimnee” and “Yuzhnouralskoe” showed the greatest increase in productivity embodiment experience “Evrikor Forte + 7” 2.5 l / ha by 25.4%, 24.3% and 22.2% respectively. Thus, the application of “Eurikor-Forte + 7” increased both the number of fruits and their weight, and also increased the yield of the studied varieties.
