The article highlights the characteristics of the three promising for Eurasia table grape varieties bread by genetics-selectioners I.A. Kostrikin and E.G. Pavlovsky with colleagues, also presented confirming photographs in color of abundant bushes, groving buds, young shoots and their tops, adult leaves, grapes and berries; the results reported about their five-year study, both in the industrial environments of OAO AF "South", Training Farm "Kuban" and the branches of the Department of Viticulture Kuban State Agrarian University, as well as in Farmer-amateur conditions of private entrepreneurs of Kuban and Don: Baikonur, Pamyati Uchitelya, Podarok Nesvetaya. These varieties fill in a modern conveyor of table varieties, previously published by us in the press, and are recommended for introduction into the State register of breeding achievements of the Russian Federation in all regions of our country for gardening use
The article highlights the issues of improving the assortment of table grape plantations for use in the farms and croft forms of management. Brief presentation of results of the five-year study of 12 table grape varieties in industrial environments for
their cultivation: in the OAO AF of "Juznaja", OOO "Phanagoria-Agro" training field "Kuban" and branches of the Department of Viticulture Kuban State Agricultural University: Citrine, Helios, Bogatyanovsky, Anthracite, Dolgogdanij,
Preobragenije, Academic K, Rochefort K, Libya K, Kubattik, Nizina and Chrysolite. These varieties are the basis of modern conveyor of table varieties and are recommended for introduction in the State register of breeding achievements of the Russian Federation in all regions of our country
Modern ampelography has reached the newest level of usage of the latest achievements of multimedia techniques and computing means of handling and analysis of assembled information. An adult leaf is a sort of "passport" of the breed, and the most important significance among set of descriptive characteristics is attached to it. For decrypting of the numeral information of leaves, it is offered to use SIAMS company toolkit, in particular - the SIAMS MesoPlant analyzer. In this article, the technique of reading (decrypting) of a leaf ampelographical information from alive and dry samples and the biometric analysis for level of morphotypical establishment of objects of researches is resulted
The morphometry of leaves of the Kuban wild-growing lianas of grape, as we know, is not learnt till now and availability of quoters of pure subspecies of Vitis vinifera silvestris Gmel is not demonstrated., though suppositions about this information soared in the scientific environment as old as Adam [5]. With the advent of a direction of morphometry taxonomy there was a necessity of accurate bracing of a current state of a genotypical diversity of lianas and biological polymorphism of leaves for link establishment silvestris - silvesatis - sativa

A flower is bisexual. A racemation is medial, cylinder-conical, medial denseness. A bacca is medial, roundish, blue - black colour, with a dense wax coating. A peel is tight, strong. Pulp and juice with the expressed high quality flavour. Sugar content of juice of baccas is very high. The crop is maintained on bushes duratingly enough. The sort is designed for production of dry red wines of the excellent quality and also for high-grade dessert and sweet wines; it is applicable for development of high-grade juice and compotes as well
New wine grape flavored pink berry grape variety
named “Radost Leonidov” breed at Athens Institute of
Viticulture by P.Zamanidi, L.Troshin and
P.Radchevskii in 2009 by crossing the new
Moskhoragos Greek muscat variety with old European
variety Traminer pink. According to morphological
and biological characteristics, it can be assigned to
Western European eco-geographical group of varieties.
Strong growth of shoots (2,1-3,0 m). The extent of
maturation of vines is very high (over the entire length,
except for the top). Duration of production period from
bud burst to harvest - 146-155 days. Productivity is
high: 20-25 t / ha. The average weight of clusters is
260. Characterized by high winter hardiness, drought
resistance and increased resistance to fungal diseases
in comparison with the varieties of Vitis vinifera.
Flower is hermaphrodite, fully developed stamens and
gynoecium. Bunch is small, conical, sometimes
winged, average density. Berry is small, spherical,
pinkish in color, with a thick waxy coating. Peel of
medium thickness, dense and durable. Pulp and juice
with a strong varietal flavor, similar to the aroma of
Traminer pink. Sugar content is very high: more than
24%. Cluster of the variety of Radost Leonidov at
overripening is drying and stored on the bushes for a
long time. The variety is intended for the production of
dry white wines of excellent class, as well as highquality
sparkling wines, dessert and sweet wines;
suitable for the production of high-quality aromatic
juices
The analyze of the genetic relationship or diversity between clones was made by using the microsatellites in the groups with black berries: Cabernet-Sauvignon and Merlot, and with white berries: Muscat white, Riesling and Pinot. It was possible to approve the objective evidence on the polymorphism between these forms during this analyze. These results become the rationale for the selection, breeding and making registration of these protoclones of four above-named varieties groups in the varieties-clones for state research: Cabernek, Cabernet Fanogoriisky, Cleret temrukskii, Merlok, Pinot white, Rieslinalk, Riesling Anapa, Riesling Fanogoriisky, Muscat Temruk, Shardonek and others. These varieties-clones are accepted by State commission of Russia, they will enrich the viticulture assortment of Anapa-Tamanskay zones of Kuban, therefore Russia too
The article presents results of studying the oenology
and the biochemistry of the Cabernet-Sauvignon
grapes in different areas of the Krasnodar region -
Taman, Anapa, Abrau-Dyurso, Gelendzhik and
Krasnodar. The yields, the mechanical composition of
the grapes, the biochemical indicators of the juice of
berries were compared. The cultivation zone affects
the yield, the average mass of the bunch, the number
and mass of berries in the bunch, the mass of the crest,
but according to the percentage of berries and crest in
the bunch, the bunch structure (ratio of mass of berries
to mass of the ridge) does not significantly differ
between growing zones. The mass of 100 berries and
100 seeds, the weight of seeds in 100 berries, the
clustering index (the ratio of pulp with juice to peel)
can differ in different places of growth, but with
insignificant coefficients of variation. The composition
of the bunch as a percentage of the total mass varies
little over the growing zones: the ridges make up 5.6-
5.7%, the skin 4.9-5.2%, the seeds 4.8-4.9%, the pulp
with the juice - 84.3-84.5%. Structural and berry
indicators varied in the range of 5.4-5.5 and 76.84,
respectively. Depending on the place of cultivation, the
yield of the grape must in laboratory conditions was
75.1-75.7%. Analysis of the structure, composition and
the structure of bunches showed that the mechanical
composition of Cabernet-Sauvignon refers to the first
group of varieties that retain their valuable
characteristics when changing the growing conditions.
When harvesting, the mass concentration of sugars was
19-19.8%, titrated acidity - 8.1-9.2 g / dm3, pH - 3.3-
3.4. Depending on the place of cultivation of the
content of organic acids in the juice of berries was:
wine - 4917-5918 mg / dm3, apple - 1926-2763, lemon
- 215-416 mg / dm3. In different places of cultivation
in% of the total amount of organic acids studied, the
content of tartaric acid varied from 61.7 to 71.4%,
apple - from 24.7 to 33.3%, lemon - from 3 to 5%.
Thus, the content of organic acids in the juice of
Cabernet-Sauvignon berries depends on the specific
growing conditions. Depending on the growing places,
the mass concentration of potassium cations is 2630-3508 mg / dm3, sodium 162-436, magnesium 171-230,
calcium 185-255 mg / dm3. However, in most cases,
as a percentage of the total cation content, there are no
differences depending on the site of growth. Thus, the
biochemical parameters of the juice of CabernetSauvignon
berries depend on the specific natural
conditions of the terrain and, according to these
parameters, the variety belongs to the second group of
varieties with less plasticity to different growing
conditions
