In the present article, the new method of DNA extraction from fresh and herbarium leafs of grape to their subsequent sequencing was described
Brandy alcohols from the grades of Muscat Berkatu, Kakhet and mixes of white grades of grapes became objects of researches. The content of some aromatic components of wine alcohols was investigated using the device of a gas-liquid chromatography Clarus-400 (with the ardent and ionization detector, a capillary column, 60 m x 0,32 mm, Elite-WAX ETR, gas-carrier-helium). Muscat alcohol according to the general content of aromatic substances (919,35 mg / 100 ml a.a.) was different from the other studied samples at the expense of the high content of ethyl acetate and izoamyl alcohol. As a result of the organoleptic analysis of a blend samples it was allocated a brandy blend with the following ratios of alcohol and wine - a blend alcohol – 74,37 %, liqueur wine – 25,63 % with strong muscat aroma and shades of taste
The article highlights the biochemical characteristics of perspective newest varieties of table grapes and clones of the Kuban region; it also presents the results of the study in an industrial environment of OAO AF "South", OOO "Phanagoria-Agro", Training Farm "Kuban" and branches of the Department of Viticulture of Kuban State Agrarian University and in Farmer-amateur conditions of private entrepreneurs of Kuban
The newest aromatic wine white berry grape variety Acropolis was breeded by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) by professors P.Zamanidi and L.Troshinym in 2006 by crossing the Greek variety Kidonitsa with European Riesling. According to the morphological and physiological characteristics it is related to the eco-geographical group of Black Sea. Strong growth of shoots (2,1-3,0 m). Degree of ripening vines is very high: over the entire length, except for the top. Length of production period 146-155 days. High yield 25-30 t / ha. Average weight of cluster is 360 g. Characterized by high resistance to cold, drought and increased resistance to fungal diseases in comparison with common varieties of Vitis vinifera L. Flower is androgynous. Bunch is medium, conical, medium density. Berry is medium, spherical, greenish-yellow color with a thick waxy coating. Cuticle of medium thickness, dense, durable. Pulp and juice are with pronounced varietal type taste of Riesling. Sugar content is very high: up to 24% more. Bunches of variety Acropolis continuously stored in the bushes. Variety is intended for manufacturing dry white wines of excellent grade and high-quality sparkling wines, dessert and sweet wines, suitable for production of high quality aromatic juices
Newest breeding aromatic grape variety with colored
pulp and juice is Traminer black bred in Athens
Viticulture Institute (Greece) P.Zamanidi, L.Troshin
and L.Maltabar in 2007 by crossing the Ukrainian
(Odessian) black varieties (Alicante Bouschet x
Cabernet Sauvignon) with the European Traminer
pink. According to the morphological and
physiological characteristics related to the group of
Western European varieties. Length of production
period 136-145 days. The strength of growth shoots is
strong (2,1-3,0 m). Productivity is high. The average
weight of bunch 200 grams. Characterized by a high
resistance to cold, drought resistance and increased
resistance to fungal diseases in comparison with
common varieties of Vitis vinifera L. Flower is
hermaphrodite. Clusters are short or medium, conical,
sometimes with wing, average density. Berry is small,
round, blue-black coloring, with a thick waxy coating.
Peel thick, dense, durable. Pulp and juice intensely
colored, with a taste of Gewurztraminer. Content of
sugar is very high: in the bushes on the stale grapes
reaches more than 40%. Prolonged preservation of
crop on bushes. Sort intended for manufacturing
intensely colored dry red wines of excellent grade and
high-quality sparkling, dessert, sweet wines and
liqueurs, and is suitable for high-quality juices. When
used in blends with other varieties, enhances
coloration, completeness of taste and improves the
bouquet of wine
The article describes two common methods for assessing the sustainability of the grape varieties to the harmful organisms: domestic [1, 4] and the international OIV [7]; the table of the comparative indicators of sustainability for these methods and the results of the evaluations of 24 varieties zoned in the Krasnodar region has been presented
The article highlights the questions of a preliminary determination of vineyard yield, studying the dynam-ics of sugar content in berries, harvesting methods of handheld and mechanized grape harvesters. We have also presented color photographs of functioning har-vesters in the vineyards
The article provides an overview of the results of the research of non-root treatment of bushes with activated water with the features of BAS. We have found that activated water, charged with the "Akvator" device through the BAS matrix has the property of impact on plant and the efficiency exceeds impact of BAS solutions themselves
This article presents the results of genotyping of new
perspective table and technical varieties and grapes
protoclones. It was established that varieties of Citrine,
Helios, Arcadia pink and Preobragenie show differ
genetic diversity in four loci
In the present article, we have described data of comparative ampelography of biometric evaluation of leaf parameters of the three table grapes: Preobragenie, Victor and Jubiley Novocherkassk, widespread in the amateur and farming areas of Russia and the Ukraine. Showed results of molecular genetic analysis of DNA from these table grapes
