BIOTECHNOLOGY – SCIENCE AND SECTOR OF AGRICULTURE
Description
This article presents information about the features of biotechnology as the driving force of scientific and technological progress. The national programs of the leading countries of the world, it is one of the priority sectors, reflecting the level of the socio-economic condition of the society. Biotechnology is now successfully solves such vital tasks as providing food, the establishment of effective medicaments, obtaining fuel based on renewable raw materials, maintaining ecological balance, conservation of biological resources of the Earth. The development of agriculture in modern conditions is impossible without agricultural biotechnology. It is directly related to viticulture. Choosing an object of an integrated system (embryos, apical meristem, axillary buds), it is possible to clone plants, i.e. produce plants identical to the original. If the same as the object to use isolated cells or protoplasts, in this case, there will most likely altered versions, creating diversity for the breeder. Genetic engineering – the science of younger, since the establishment of the first chimeric DNA molecule. The origin of genetic engineering is rooted in the development of molecular genetics, biochemistry. These technologies, undoubtedly progressive, but their biological safety is still insufficiently explored and is a danger to all life on Earth. The leading Western powers carried out strict control over the introduction of transgenic crop plants, as they are in agrocenosis new biological risks that may adversely affect the plants, animals and humans. In Russia, as in other countries, have already adopted the law “State regulation of genetic engineering”

VASILY NOSULCHAK - THE NEWEST COMPLEX-RESISTANT TABLE SEEDLESS WHITE GRAPE VARIETY
Description
Vasily Nosulchak, the newest complex-resistant tableless seedless grape variety, was bred in Greece by Pantelei Zamanidi and Leonid Troshin in 2013 by crossing the Talisman variety with the Yanaky variety. The created variety is a complex inter-species Euro-American-Amur hybrid. The duration of the production period is 146-155 days. The growth of shoots is strong. The degree of grapevine maturing high. Yield is very high. Percentage of fruit-bearing shoots 90. Average weight of bunches 900 g. It is stainable for high winter hardiness, drought resistance and increased resistance to fungal diseases, tolerant to phylloxera. The top of the young shoot is green without pubescence. Young shoots are green, without pubescence. The flower is hermaphroditic. The cluster is large, conical, branching, winged, of medium density. The berry is medium-sized, short elliptical, green-yellow. Peel is thin, strong. The pulp is juicy, with a varietal flavor. The sugar content is high. Rudiments of seeds are soft. The variety is intended for fresh consumption and kishmish production. The table high-yielding seedless variety Vasiliy Nosulchak in terms of winter hardiness, resistance to diseases and pests significantly exceeds all Eurasian varieties of table and kishmish designation. Can be used as a table grapevine for fresh consumption on site and for export, as well as for the production of high-quality dried products. As a winter-hardy variety, it is very promising for cultivation in covered viticulture zones, where table varieties require shelter for the winter. It is of great interest for selection work in breeding frost-resistant, diseases and pests of seedless varieties. To determine the influence of different ecological conditions on the growth, development, quantity and quality of the crop, the variety must be tested on all continents in different ecological and geographical areas of cultivation - in the grapes producing countries of America, Eurasia, Australia, Africa

INFLUENCE OF FRUITLESS SHOOTS ON QUANTATIVE TRAITS OF GRAPES AND WINE OF SAPERAVI VARIETY
06.00.00 Agricultural sciences
Description
In this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same

INFLUENCE OF FERTILIZERS ON QUALITY OF CHARDONNAY GRAPES AND WINE MATERIALS
Description
The article presents the results of the fertilizers use effect on dry wine materials produced from the Chardonnay variety, grown in the Anapo-Taman soil and climatic zone of the Krasnodar region, Russia. As a result of wine materials analysis, increase of tartaric acid was noted, with the autumn application of phosphorus-potassium fertilizers and the spring application of ammonium nitrate. At the same time, its optimum content was noted with nitroammophos. Also, the minimum concentration of malic acids was detected by the application of nitroammophos with potassium fertilizers. In its turn, early spring application of ammonium nitrate reduced the concentration of malic acid below the control sample (without fertilizers). It was revealed that the use of mineral fertilizers in this winemaking zone also contributed to a reduction of lactic acid in the must. At the same time, the application of nitroammophos (especially together with other mineral fertilizers), contributed to the accumulation of citric and succinic acids, as well as phenolic compounds. Moreover, the application of phosphate-potassium fertilizers in the autumn contributed to the accumulation, and, consequently, also to the increase in the content of phenolic compounds in the resulting must. In addition, the studied samples of wine materials contained high alcohol concentrations and low concentrations of sugars with volatile acids. At the same time, the maximum amount of alcohol exceeding its content in the control sample was revealed when phosphorus-potassium fertilizers were used together with nitroammophos fertilizers. It is also noted that the application of ammonium nitrate did not affect this indicator. As a result, the use of mineral fertilizers in the studied concentrations made it possible to prepare wine materials that contained a low concentration of sulfur dioxide, which is substantially lower than the harmful concentration for humans. In addition, increased concentrations of hydrogen ions in variants with the application of phosphate-potassium fertilizers have made it possible to reduce the number of iron tanates and the intensity of oxidation-reduction processes
