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 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, Letnee polosatoe (K); winter – Orenburgskoe pozdnee, Zimnee, YUzhnoural'skoe (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 YUzhnoural’skoe 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 "Evrikor − Forte + 7" increased both the number of fruits and their weight, and also increased the yield of the studied varieties.

Abstract 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.

Abstract This research explores the compactness of apple varieties and forms with different types of crown. Orchards on semi-vigorous rootstocks with density and high density planting systems are cost-effective in modern horticulture. For making such gardens, it is necessary to have trees with special compact crown shape. They ensure the high-quality fruits production, meeting the requirements of world standards. To date the most perspective apple varieties and forms for domestic intensive gardening from the rich gene pool of the Selection and Genetic Center of Federal State Scientific Institution «I. V. Michurin Federal Scientific Center» are identified. Varieties of folk domestic and foreign breeding took part in the creation of new genotypes. Apple varieties and promising forms (more than 160 genotypes), including from near and far abroad selection, were used as materials for crown features studying. We conducted our study by the following indicators: tree height, crown volume, “degree of compactness” and the shoot-forming ability. We found that the genotypes Sholokhovskoye, Zvezda Artemyeva, 25-7(11), 40-9(8), 36-8(21), 40-9(6), 8-7(72), 40-9(7), 36-8(17), 62-5(140) have optimal crown parameters. We recommend their use for industrial horticulture and further breeding to create restrained growth, low-volume crown, and a high degree of compactness varieties.

Researches were conducted in 2019-2020 in the department of closed artificial agroecosystems for plant growing on the basis of Federal State Budgetary Scientific Institution “Federal Scientific Agroengineering Center VIM”, Moscow. The object of the study was the seeds of tomatoes Solanum lycopersicum L. The aim of the research was to study the effect of a biostimulant (succinic acid) on biological characteristics and productivity of Solanum lycopersicum L. grown in the substrate hydroponics of a climatic chamber. As a result of conducted researches, there was identified the most effective method of using succinic acid as a biostimulator – inoculation of seeds, which contributed to an increase in yield with a significant rise in relation to the control – 64.1%. The average fruit weight in this variant was 114.1 g, which exceeds the control by 37.0%. The complex application of the biostimulator provided an increase in the average fruit weight in 18.6%, the addition of hydroponics to the nutrient solution is 4.1%.

The results of a long-term ecological testing of 12 apple varieties of domestic and foreign selection in the Republic of North Ossetia-Alania are presented. The biological features of fruiting of representatives of the genus Malus in a southern region of Russia were studied with the purpose of identifying the most valuable varieties in terms of a set of indicators for further breeding and production. According to the conducted long-term observations (2012–2019), the following varieties with compact small-sized crowns (volume of 1.48-2.09 m3) were identified: Zolotaya Korona, Lyubimoe Dutovoj, Sunrise and Red Chiff. Among summer triploid varieties, the variety of Soyuz was selected according to the yield factor (total yield was 159.2 t/ha, which was 56.5 t/ha higher than the control). The varieties of early winter and winter ripening period with a high total (198.3–299.2 t/ha) and average (33.05–49.87 t/ha) yield were determined: Ligol, Zolotaya Korona, Lyubimoe Dutovoj, Alanskoe and Pinova. It was established that the varieties of Alanskoe, Zolotaya Korona, Lyubimoe Dutovoj, Sunrise and Pinova exhibit high productivity indicators, with the specific productivity of the crown volume being 17.00–21.87 kg/m3. It was revealed that the fruits of all studied foreign and domestic apple varieties grown under favourable conditions of the region meet modern requirements in terms of diameter (65–75 + mm) and average weight (200–220 g). Among the most promising varieties for breeding and production were found to be Liberty, Zolotaya Korona and Lyubimoe Dutovoj with large fruit (214.5–237.8 g), as well as Soyuz, Ligol, Alanskoe and Prikubanskoe with very large fruit (289.3–330.2 g). It is concluded that the apple varieties of regional selection (Alanskoe, Zolotaya Korona, Lyubimoe Dutovoj, Soyuz) and foreign selection (Sunrise and Pinova) can be recommended when breeding varieties with the required set of valuable agrobiological propertites, as well as when creating intensive industrial plantings and obtaining high-quality domestic fruit products.
