abstract 1131509062 issue 113 pp. 841 – 854 30.11.2015 ru 1119
The article presents the results of the studies of 11 varieties cultivated in the eastern region of South Coast wine-growing zone of Crimea (planting of "Solnechnaja Dolina ", near Sudak mountain) in the area of their natural growing, where was formed the gene pool of grapes for a long time. As a result, the three-year (2010-2012) study found that the majority of indigenous varieties had small number of fruitbearing shoots in the bush: the varieties with colored berry - 53,3-73,3%, in white-berry - 46,6-75,9% except Shabash variety - 79.9%. We have identified the most productive varieties which were Dzhevat kara (62.2 t / ha), Kokur Beliy (48.9 t / ha), Kapselsky Beliy (44.4 t / ha), and varieties with female type of flower: Kefesiya, Ekim kara, Kock pandas, Sary pandas and Crona gave not high yield: 22.2; 22.2; 24.4; 28.9 and 28.9 t / ha. On the strength of growth, productivity and the accumulation of sugars in the juice of berries, we picked out varieties of Dzhevat kara, Crona, Kapselsky beliy. According to the main economic indicators, it turned out that the most profitable varieties are Dzhevat Kara, Kokur beliy and Kapselsky beliy. Hence, these varieties in conditions of the Crimea have much greater prospect of reproduction and development of production

STRUCTURAL AND PHYLOGENETIC ANALYSIS OF VVMYBA1, VVMYBA2 AND VVMYBA3 GRAPEVINE GENES

abstract 1341710026 issue 134 pp. 303 – 327 29.12.2017 ru 1059
The article presents the structural and phylogenetic analysis of VIT_02s0033g00410, VIT_02s0033g00390 and VIT_02s0033g00450 genes of the grapevine genome and the closely related orthologous gene MYB114 of the Arabidopsis genome. These genes are responsible for the biosynthesis of anthocyanin in the organs of model plants and are of interest not only for practical production and breeding, but also for fundamental research. These genes were analyzed for GCcomposition of nucleotides, the presence of cisregulatory elements and promoter regions. DNA and protein sequences were aligned to look for similar elements, which allowed further analysis of the ultraconservative domains of four genes. Based on the results of search and identification of the conservative regions, a cluster tree was constructed, which made it possible to identify the separation of gene sidelines from, presumably, the main one. At the same time, the construction of consensus trees based on DNA and protein sequences revealed their absolute similarity. "The Minimal Evolution Tree" allowed calculating the approximate dates of the appearance of the mutations and the divergence times of the gene branches between each other. At the same time, the appearance of the Vitis genus and its separation from the Rosales was taken as the time first divergence point. In the end, homologous metabolic pathways were searched between grapevine and Arabidopsis, which revealed the presence of homologous proteins in the grape proteome. In this turn, it already confirms the existence of similar biosynthetic pathways and, as a consequence, interactions such as "DNA-protein" and "protein-protein"

abstract 1061502079 issue 106 pp. 1179 – 1194 28.02.2015 ru 984
The article contains the results of the study of mechanical composition of grapes and biochemical characteristics of white wine grapes for the production of juice of direct extraction and blending. Thus, the yield of studied grapes ranged from 7.5 to 13.2 t / ha: highest yielding varieties and hybrids of Pervenets Magaracha and Tsitronnyy Magaracha, and the lowest - Chardonnay and Pinot blanc. At an average weight of clusters of varieties were divided into three groups - large clusters (230-243 g) in varieties Pervenets Magaracha and Tsitronnyy Magaracha, medium (181-184 g) - the varieties Chardonnay and Pinot blanc, small (112-116 g) - the varieties Bianca and Viorica. By weight of the 100 berries were divided into four groups - Bianca and Viorica (I), Pervenets Magaracha (II), Chardonnay (III), Pinot blanc and Tsitronnyy Magaracha (IV). Weight of 100 seeds from the largest varieties Pinot blanc and Bianca, and the lowest - in the varieties of Tsitronnyy Magaracha and Chardonnay. The solids content in the juices of these varieties ranged from 19.4 to 21.8%, which corresponded to branded products and higher of commodity varieties. Mass concentration of sugars ranged from 18.4 to 21.3 g / 100 cm3. Titratable acid content in the juice was varied from 0.65 to 0.78 g / 100 cm3. Sugar-acid ratio, defined as the ratio of concentration of sugars and titratable acids ranged from 23.6 to 30. The recommended values for this indicator were within 22-30. According to the results of the tasting, we rated "excellent" the juices from the varieties of Tsitronnyy Magaracha, Viorica (19 points) and Bianca (17 points); "good" marks were given to the juices from Pinot blanc, Chardonnay, Pervenets Magaracha: this means that we can get juices of excellent quality from the grape varieties under study with the title of ampelographic variety; in addition, the juice of the grape of varieties Chardonnay, Pinot blanc, Bianca, Pervenets Magaracha due to their potassium content will be functional to improve the cardiovascular system. On the basis of the tasting we have conducted mixing of the juices from the varieties of Viorica and citron Magaracha with other juice varieties 50:50 and 70:30. Sensory evaluation showed that blending juices from the varieties of Viorika and citron juice Tsitronnyy Magaracha other varieties improves product quality and 50:50 increases by one the total score, and 70:30 - two units. Blend of the varieties of Viorica and Tsitronnyy Magaracha does not increase the total score, but gives the product a special flavor and aroma. Hence, using the grape varieties under study we can produce varietal juices with the name of their ampelographic type and blended juices to extend the assortment
