06.01.01 General agriculture, crop production (agricultural sciences)
Description
In the article, we have studied the influence of biological nitrogen deposition on the physical and chemical parameters of natural semi-sweet wine, on the example of two grape varieties – classic European Chardonnay and interspecific hybrid Ekaterinodar, including amino acids and aroma-forming components. It is established, that the use of the proposed technology contributes to the active consumption of amino acids by yeast in the fermentation stage. At the same time, yeast cells consumed most actively alanine, valine, phenylalanine, histidine, aspartic, aminobutyric, glutamic acids, leucine, lysine, Sirin, tyrosine, threonine. A slight increase in the concentration of amino acids was observed at the end of fermentation, when the yeast cells entered the stationary phase of development. However, the content of all amino acids, with the exception of Proline, in the wine material was less than in grapes and fermenting wort. As a result of biological nitrogen deposition in experimental versions, the concentration of nitrogen compounds (total and amine nitrogen) was three times less than in the control ones. There is a difference in the concentration of flavor-forming components in wines prepared from both grape varieties using different technologies. In experimental versions, we observed a greater accumulation of almost all components of the aroma-binding complex (especially esters, terpenes, phenylethanol, and ionone), with the exception of higher alcohols. Experimental samples of natural semi-sweet wines from the Chardonnay and Ekaterinodar grape varieties were characterized by a bright floral and fruit aroma and had a higher tasting rating in comparison with the classic technology

06.01.01 General agriculture, crop production (agricultural sciences)
Description
We have studied 17 strawberry varieties due to their economically valuable traits: the number of berries (pcs per plant), average fruit weight (g), biological yield (g per plant), firmness of fruit (g). Among the studied varieties is 6 - Honeoye, Alba, Belrubi, Asia, Nelli, Bogota are zoned varieties; 3 - Djeni, Elegia, Kemia is a new varieties of local selection and 8 an introduced varieties from the EU - Joly, Onda, Galia, Vivaldi, Rumba, Florence, Alina, Molling Opal. The purpose of the work is to identify the strawberry varieties which are promising for industrial production in the south of Russia among new strawberry varieties of local selection and introduced varieties. Based on two-factorial analysis of variance according to 2018-2019 studies there were revealed significant differences between the genotypes of varieties for all studied parameters. It is shown that the greatest differences in the variability of traits are observed by the “year” factor. The varieties were ranked according to the values of the smallest significant difference for each individual trait. In accordance with the results of the cluster analysis on a complex of traits we have identified strawberry varieties which are showing the prospect for industrial cultivation. In the new varieties of strawberries as Joly, Vivaldi and Rumba the values of yield and quality of berries are comparable to the best zoned varieties, such as Nelli, Asia and Bogota

06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article considers the types of functional stability of reproduction processes in industrial fruit growing. We have substantiated the necessity of developing methodological bases for ensuring and managing the stability of reproduction processes. Methodological bases for managing the stability of reproduction processes have been developed, taking into account the specifics of industrial fruit growing as a complex organized system, consisting of biological, technogenic and economic subsystems. We have also proposed an algorithm for ensuring and managing the sustainability of reproduction processes, which is the basis for the development of digital technologies for managing the sustainability and efficiency of industrial production. The work reveals and defines factors influencing the level of sustainability and efficiency of reproductive processes, the relationship and interaction between result indicators and factor variables; it identifies emerging imbalances in the organization of reproduction processes in industrial fruit growing. Using methods of mathematical statistics, we calculated an integral indicator of the functional stability of reproductive processes and gave its semantic interpretation. It was found that the structural elements of reproduction processes are inconsistent with the actual indicators that characterize functional stability, with the normative parameters. This trend makes it necessary to develop a mechanism for managing sustainability and tools for influencing functional zones in order to bring actual indicators to the standard level. When developing tools for sustainability management, the following were clarified: management methods, process goal setting, functional load of the management object, level of organization, various restrictions (criteria) related to the specifics of technological and economic relationships and mutual influences. We have developed a mechanism for ensuring and managing the functional stability of reproduction processes in industrial fruit growing by its types, including the following stages: automated database formation; cognitive analysis of the influence of factors on the functional areas of influence by types of stability; assessment of functional stability and justification of the integral indicator; filling in, compensating for missing information, generating information data; determining the optimal parameters of functional stability; developing regulators for leveling functional imbalances in the organization of reproduction processes that ensure effective and sustainable management of industrial production

Description
This article is devoted to the definition of criteria for the functioning of agrocenoses. It is determined that the functioning of agrocenoses largely depends on the resource potential: used ecological zones, applied technologies, technological operations and regulations. The basis of effective reproduction and sustainability of agrocenoses is the optimal balance of resources used. The work purpose is the substantiation of optimal parameters of resource intensity of the technological processes in horticulture and the determination of the limits of sustainability of agrocenoses under anthropogenic influences. The integrated assessment of resource intensity of production and technological processes in industrial fruit growing for optimization of its parameters of resource intensity is given. The optimum of reproduction possibilities and limits of stability of agroecosystem components in comparability with the level of technogenic load is achieved by means of regulation of permissible anthropogenic loads in separate elements of agroecosystem and resource balance of elements and processes. The limits of sustainability of fruit agrocenosis under anthropogenic influences are substantiated as well. Regression dependences on technological processes in the context of certain types of resources used are established: capital (depreciation), turnover (material consumption and coefficient of consolidation) and labor (wage). The complex coefficient of efficiency of the economic mechanism of resource saving is defined. The article substantiates optimal parameters of resource-intensive production and technological processes in industrial horticulture. We have also calculated the normative value of the total index of resource intensity of technological processes

APPLE ROSETTE DISEASE IN NORTH CAUCASUS PLANTATIONS
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article presents the results of a study of the apple tree rosette disease found in a collection garden and having a viral nature. The rosetting has typical signs of manifestation. Sick plants develop narrow small chlorotic leaves. Rosettes of leaves on the upper cervical and lateral shoots are formed as a result of the convergence of internodes. The spread of the rosetting in the planting reaches 10-11 %. The prevalence of viral disease varies among the 44 varieties of apple trees of different ecological and geographical origin. So, the lesion of rosetting was noted on single trees in the varieties of Gala Redi Red, Fujiko, Red Free, etc., and it was a complete defeat in the variety of Piros. A different degree of the manifestation of the disease on the trees was established: from partial manifestation on individual shoots, to aggressive damage to the entire crown of the tree. On young trees bearing fruiting (3-4 years from planting), the rosetting reduces the yield of apple trees by 36 %, ¼ part of the fruits on the trees are small in size compared to the fruits of healthy trees. The infectious nature of the rosetting is confirmed by the transfer of the disease on the most affected Piros variety using summer budding

DEVELOPMENT OF MULTIPLEX SETS OF SSR MARKERS FOR GENOTYPING APRICOT VARIETIES (PRUNUS ARMENIACA L.)
Description
Genetic studies of apricot are the actual direction in the genetics of fruit crops. In this regard, the improvement of the collection of SSR markers for the genotyping of this culture is an objectively significant task. In a study for the 16 SSR-markers previously developed on almonds (PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1, PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1) and Siberian apricot (A3-72, A1-63, H2-22, A3- 7-1, H2-5, A1-7, A3-9, H2-45), approbation and evaluation of the prospects of using for genotyping Prunus armeniaca L. were performed. Approbation, performed on 3 varieties of different origin, revealed markers and their combinations optimal for their use. During the study, all tested DNA markers were grouped into multiplex sets, including 4 markers. This allows carrying out genotyping simultaneously on 4 loci in the formulation of one reaction. One marker (PdUnchar2) from the studied sample included in the multiplex set did not show amplification. Five markers gave a monomorphic product. The remaining 11 SSR markers allowed us to obtain polymorphic, cultivar-specific SSR fingerprints for all the studied cultivar. These multiplex sets are proposed for use in studying the genetic polymorphism of the species Prunus armeniaca L.
