Newest wine Muscat grape variety with colored pulp and juice Serra was breeded at Athens Institute of Viticulture (Greece) by P.Zamanidi and L.Troshin in 2007 by crossing the Ukrainian Odessa black variety (Alicante Bouschet x Cabernet Sauvignon) with the new Greek Muscat black berry Krimbas variety. According to the morphological and physiological characteristics it is included in the eco-geographical group of Black Sea Coast. Length of production period is 146-155 days. Strong growth of shoots (2,1-3,0 m). Percentage of productive shoots is over 90. Productivity is very high: 25-30 t / ha. Average weight is 350 g. Grapes characterized with high resistance to cold, drought and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite, with the stamens and fully developed gynoecium. Cluster is medium, conical, sometimes with wing, medium density. Berry is small, round, blue-black, with a thick waxy coating. Peel of medium thickness, dense, durable. Pulp and juice are intensely colored, flavored with Muscat taste. Sugar content is very high, in the bushes at sun-dried bunches up to more than 40%. Prolonged preservation of crop on bushes. Variety is intended for manufacturing intensely colored dry red wines of excellent grade and high-quality sparkling, dessert, sweet and liqueur wines, and is suitable for the manufacture of high quality intensively colored juice with Muscat taste.

RESEARCH OF VINE MATERIALS OF PROTOCLONES OF SAPERAVI GRAPES IN "POBEDA" JOINT-STOCK COMPANY

abstract 0530909002 issue 53 pp. 11 – 21 30.11.2009 ru 2224
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria

REGENERATIVE PROPERTIES OF GRAPE CUTTINGS UNDER THE INFLUENCE OF TREATMENT WITH IAA

abstract 0771203099 issue 77 pp. 1190 – 1219 30.03.2012 ru 1831
The article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings

QUANTITATIVE MEASUREMENT OF THE SIMILARITIES AND DIFFERENCES OF CLONES OF GRAPES USING CONTOURS OF LEAVES WITH THE USE OF ASC-ANALYSIS AND "EIDOS" SYSTEM

abstract 1161602077 issue 116 pp. 1200 – 1223 29.02.2016 ru 682
The article discusses the application of automated system-cognitive analysis (ASC-analysis), its mathematical model is a system of information theory and implements, its software tools – intellectual system called "Eidos" for solving one of the important tasks of ampelography: to quantify the similarities and differences of different clones of grapes using contours of the leaves. To solve this task we perform the following steps: 1) digitization of scanned images of the leaves and creation their mathematical models; 2) formation mathematical models of specific leaves with the application of information theory; 3) modeling the generalized images of leaves of different clones on the basis of specific leaves (multiparameter typing); 4) verification of the model by identifying specific leaf images with generic clones, i.e., classes (system identification); 5) quantification of the similarities and differences of the clones, i.e. cluster-constructive analysis of generalized images of leaves of various clones. The specific shape of the contour of the leaf is regarded as noise information on the clone to which it relates, including information about the true shape of a leaf of this clone (clean signal) and noise, which distort the real shape, due to the random influence of the environment. Software tools of ASA-analysis which is intellectual "Eidos" system provides the noise suppression and the detection of a signal about the true shape of a leaf of each clone on the basis of a number of noisy concrete examples of the leaves of this clone. This creates a single image of the shape of the leaf of each clone, independent of their specific implementations, i.e. "Eidos" of these images (in the sense of Plato) - the prototype or archetype (in the Jungian sense) of the images

OPTIMIZATION OF THE LENGTH OF TRIMMING AND THE LOAD OF BUSHES WITH BUDS OF DIFFERENT VARIETIES OF GRAPES IN TAMAN

abstract 1241610074 issue 124 pp. 1162 – 1181 30.12.2016 ru 558
Numerous studies have found a different quality of the buds along the length of the fruit arms, which expressed various degrees establishing embryonic inflorescences in the central buds. It is revealed that many of the grapes have more fruit-bearing eyes formed on average (4-6 knots) and upper (7 to 10 knots) levels of fruit escape, compared to the lower (1-3 nodes) layer. In connection with the different quality of the buds along the length of fruit vines should be used and different ways of cutting them. It is necessary to consider the biological characteristics of varieties, ways of doing and shaping the bushes, the weather conditions of the area during the growing season and relative calm. To receive annually a stable high yield of grapes, we must first set the optimal length of pruning fruit shoots and optimal load on the Bush healthy eyes. This requires for each class on the eve of trimming bushes to carry out the analysis of the wintering holes along the length of the fruit shoots and to identify the embryonic fruitfulness of Central buds, i.e. to carry out the prediction of grape yield next year. The article presents data on the formation of the embryonic fruitfulness of Central buds of wintering buds at the Taman group of grapes – Arcadia, Viorica, Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot white, Riesling, Saperavi, Traminer pink, Tsimlyansky black, Chardonnay. Found higher rates of embryonic fruitfulness of Central buds buds in the studied grape varieties - Chardonnay, Riesling, Viorica, Hibernal, Merlot, Moldova, where the coefficients of fruiting ranged from 1.40 m from Riesling to 1.69 from Merlot; factor productivity of 1.58 from the Chardonnay to 1.77 from Merlo. The high percentage of fruitful buds from 80,8 from Cabernet Sauvignon to 95.6 in the cultivars Merlot and Chardonnay. A higher percentage of eyes with 2 embryonic buds in the cultivars Merlot and Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of grapes next year to trim the bushes on the proposed method will provide a full crop of grapes
