Zorin – creator of the Friendship Tree, candidate of agricultural sciences (1944), are considered. Fyodor Mikhailovich developed valuable varieties of mandarin oranges, grapefruits, lemons, plums, figs, and hazelnuts. Author of more than 40 scientific papers. He was awarded the State Prize for the creation of new varieties of fruit plants. This article shows theoretical research and practically used methods for breeding new varieties of citrus fruits. The basis of his research was vegetative hybridization (from Greek “hybris” – inbreeding) – the production of hybrids by grafting. Zorin F.M. paid a special role in the breeding work to “tree gardens”, which were of both scientific and industrial importance. Fruits from such a tree could change shape, size, color and ripening time. At the same time, he paid attention not only to the selection of the scion, but also the rootstock. As a result, such a tree had many trunks, and the crown consisted of numerous varieties and species of three genera – Citrus, Fortunella, Poncirus of the Rutaceae family. Almost the entire Pomeranian subfamily (Aurantioideae) grafts onto each other and is highly compatible. It is important to take into account varietal characteristics: timing of flowering and ripening, as well as their biology. The main advantages of citrus «tree-gardens» are the saving of garden space, the aesthetic appearance of the trees and originality, as well as the ability to obtain more varieties per unit area.","PeriodicalId":504482,"journal":{"name":"Fruit growing and viticulture of South Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140494758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is possible only if predictive models of the behavior of the grape variety or its scion-rootstock combination are developed in the grafted culture in various ecoagrobiocenoses. The purpose of the study was to consider methodological approaches to the creation of mathematical models for predicting the behavior of an individual variety or groups of grape varieties, depending on the abiotic and agrotechnological characteristics of cultivation. To achieve this goal, a previously created database was used, obtained during an experiment conducted on the basis of uterine plantations and an open grape school of the Institute \"Agrotechnological Academy\" of the V.I. Vernadsky Crimean Federal University, collected in the period from 2018 to 2021 and subjected to multidimensional regression analysis using the developed program. The total number of items included in the database is 1,860. (31 parameters). The research proved the possibility of developing regression models for predicting productivity using nonparametric digital introduction of varieties, as well as environmental factors. It is established that regression models characterizing the quality of the vine, taking into account varietal characteristics and weather conditions, can vary depending on a particular variety. Thus, a similar model for the Cabernet Sauvignon variety is fundamental with a multiple correlation coefficient of R = 0.9866, and for the Syrah variety it is logarithmic at R= 1.0000.

Therefore, it is very relevant to use scion-rootstock combinations based on rootstocks with high drought resistance in creation mother-cutting orchards of apple trees in the “Basic” category. In the conditions of Krasnodar, the summer months of 2018-2023 became hotter, which is confirmed by data on the excess of the average monthly temperature over long-term values. July was the hottest in 2018, 2020 and 2021. (38.0, 38.0 and 36.3 ºC, respectively). In August, the excess of the long-term norm was greatest in 2018, 2021 and 2023. The trend of increasing temperatures in the autumn months has led to a lengthening of the growing season and a decrease in the resistance of apple plants to unfavorable overwintering conditions, which can negatively affect the quality of cuttings. The purpose of the research was to identify the most adaptive apple tree rootstocks for use in mother-cutting plantings of the «Basic» category. We assessed the drought resistance of the most common introduced apple rootstocks M 9, MM-106 and the rootstock breed by FSBSI NCFSCHVW SK 2U under conditions of high-temperature stress during the summer growing season. Leaf water content in particularly hot years (2020, 2021, 2023) was predominantly higher in the M 9 and SK 2U rootstocks. The best water-holding capacity of leaves was observed in the rootstocks M 9 and SK 2U, the worst – in the rootstock MM-106. Preference should be given to the semi-dwarf rootstock SK 2U when designing mother-cutting apple tree plantings of the “Basic” category.

The article analyzes the range of insecticides allowed on pear against pear psylla, which is represented by preparations from 8 chemical classes. To reduce the resistance of pear psylla to the used pesticides, it is necessary to expand the range of broad-spectrum insecticides against this phytophagan. In this study, insecticides with larvicidal action, such as Voliam Flexi, SC, Lirum, SC, Lufox, EC, were tested in laboratory conditions. The characteristics of the used pesticides are given and the mechanisms of their action are described.Samples of annual pear growth were selected in the Prikuban zone of the Zakuban horticulture subzone of the Krasnodar region, Ust-Labinsk district. As a result of the study, it was found that the following pesticides have the best biological efficacy against nymphs (first-third age) of pear psylla: Voliam Flexi, SC with a consumption rate of 0.5 l/ha and Lirum, SC 1.5 l/ha. On the seventh day, they showed a maximum biological efficacy of 100 %, which was at the level of the standard preparation Movento Energy, SC. In this experiment, Lufox, SC had low efficacy, due to the fact that the drug has a longer mechanism of action, it takes 10-12 days for a good effect.

It is noted that an air temperature of +14 ... +30 ºC and a relative humidity of 52 % are necessary to maintain viability and fertility. The eggs of the buffalo ceresa leafhopper overwinter in the branches and trunks of trees of woody species, often in young annual shoots. The female ovipositor cuts the bark and lays eggs in two rows of 5-11 eggs. Damage by the buffalo ceresa leafhopper causes a violation of the flow of nutrients to the tops of shoots, weakening and a sharp decrease in their growth. The rose leafhopper gives up to 4 generations during the summer. Damaged leaves turn yellow, photosynthesis processes are disrupted in them, plant nutrition deteriorates, which affects the reduction of economically valuable indicators. The presence of sucking pests increases the risk of spreading viral diseases. Insecticides and phytosanitary monitoring are most effective in fruit-bearing vineyards only in combination with high agricultural techniques of cultivation. In this connection, there is a decrease in yield losses and environmental pollution with chemicals. Therefore, it is necessary to deal with weeds in a timely manner, to carry out maintenance work to ensure good ventilation of grape bushes, to regularly carry out phytosanitary monitoring of the population with sugescent pests and diseases, to carry out row-to-row tillage.
