06.00.00 Agricultural sciences
DescriptionIn the article we have studied 55 aboriginal varieties, collected in the North Caucasus. We have described allelic diversity and identified four haplotypes. All the populations were closely related while being examined using a factor of Nei's genetic distance (Dn), with the exception of indigenous varieties of Armenia. Maximum differences have been found between the Uzbek population and Astrakhan, Turkmenian, Armenian populations. The most genetically rich were the population of Don area and Krasnodar region

THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS
06.00.00 Agricultural sciences
DescriptionVitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection

DescriptionIn peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)

TECHNIQUES AND ALGORITHMS OF INTERACTIVE AUGMENTED REALITY VISUALIZATION: RESEARCH AND DEVELOPMENT
DescriptionThe author performed a research with the purpose of improving visualization of three-dimensional objects by means of augmented reality technology with the use of massively available mobile devices as a platform. This article summarizes the main results and provides suggestions for future research. Since graphical user interfaces made it to the consumer market about 30 years ago, interaction with the computer has not changed significantly. The focus of current user interface techniques is only on human-computer interactions, not on human-real world interactions. With that in mind, the concept of augmented reality appears very promising. Besides other improvements, it provides a better user interface for visualization of virtual objects in real environments. Modern smartphones and tablet computers, as well as improved software tools have provided the prerequisites for mass usage of handheld augmented reality. The following issues were raised by research: realistic object rendering, the ability to change object parameters in real time, storing of objects, manipulation of objects in space, issues of augmented reality graphical user interface design

RESEARCHING AND CREATION OF A DEVICE FOR DRYING CHICKEN MANURE
DescriptionIn this article the authors have proposed a process and arrangement for recycling in the poultry farms of the Krasnodar region of chicken manure and release of mineral fertilizers, аs well as the analysis of existing Russian technologies and devices for drying chicken manure. The study proposed a technology and apparatus for drying chicken manure to not only provide a significant deal of capital investments, but also cut energy costs by the proposed method and apparatus, as well as improving the quality of the finished product (chicken manure). In the method of drying chicken droppings produced removing mechanical impurities, mixing, drying and grinding of the hot gases, wherein the starting slurry is transported in a horizontal direction opposite to the flow direction of the hot gases while performing a gradual heating it with simultaneous comminution and mixing, and then after reaching the zone of maximum temperatures for each of the size fractions of the suspension is achieved by turning its direction on 180ºС and then transported in a direction coinciding with the direction of flow of the hot gases by carrying out the gradual cooling of the heat transfer starting product. We have also presented norms of dry chicken manure application under agricultural crops in the Krasnodar region

Description
Currently, there is increasingly reduced number of the sites convenient for construction. In this regard there is a question of development of new territories, for various reasons which were earlier considered economically unprofitable or unsuitable for construction. Often, for construction in the mountain area it is necessary to carry out construction of objects in landslide territories. However, landslide processes constitute big health hazard and lives of people and also safety of buildings and constructions. The main objective of engineers when performing design and exploration work on landslide territories is the determination of stability of slopes and size of landslide pressure from soil and also identification of the most dangerous combination of loadings which can demand design and construction of a construction against landslide of landslide protection structures with significant load-bearing capacity. The research presented in article allows to define the most dangerous loads affecting the stability of the slope and also of the selection of a protective construction (against landslide). Dependences of change of landslide pressure and coefficient of stability of a slope are received from action of various loadings (both static, and dynamic)

Description
Modern domestic tomato hybrid should be competitive with tomato hybrids of foreign selection. To create a model of a future hybrid, a collection of modern tomato hybrids of domestic and foreign selection presented on the seed market was investigated. During the study, a modern method of genetic study of the genotype of tomato Real-Time PCR was used. As a result of the study, a model of a modern tomato hybrid with tolerance to powdery mildew of tomato was described. In the future, it is planned to carry out breeding work to create such a hybrid. In the course of studying the F1 collection of tomato hybrids, it was found that the modern model of a tomato hybrid should have the following characteristics: a semi-vegetative type of growth with closely spaced internodes, early and medium ripening, a simple type of inflorescence with 4–5 fruits if the average weight of fruit is more than 200 grams; with 6–7 fruits weighing up to 150 grams for collection by tassels. High strength of fruits with the absence of concentric and radial cracking, suitable for long-distance transportation, is required. In the genotype of the modern hybrid model, in addition to tomato powdery mildew resistance (Oidiun lycopersici), it is necessary to have a complex of resistance genes to such diseases as tobacco mosaic virus (Tomato mosaic tobamovirus), Fusarium oxysporum, verticillosis wilt of the tomato; ), brown spot of tomato (Cladosporium fulvum). It is also desirable the presence of a gene of resistance to the yellow leaf curl virus of tomato (Tomato yellow leaf curl virus) and the gall nematode (Meloidogyne incognita)
