Newest technical black berry variety named Piste (“Faith” in Greek) with colored flesh and juice breeded at Athens Institute of Viticulture (Greece) by researchers Zamanidi P., L. Troshin and P. Radchevskii in 2007 by crossing the Greek varieties Afoos (Mavrodafni x Alicante Boucher) with Ukrainian variety Odessa black (Alicante Bouchet x Cabernet Sauvignon). Duration of production period is 146-155 days. Growth of shoots is strong (2,1-3,0 m). The percentage of productive shoots is more than 90. The yield is very high: 25-30 t / ha. The average weight of clusters is 250 g. It can be characterized by high winter hardiness, drought resistance and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite. Cluster is medium, conical, sometimes with wings, medium density. Berry is small, round, blue-black color with a thick waxy coating. The skin is medium thickness, dense and durable. Pulp and juice are intensely colored. Very high sugar content. Variety is intended for the production of intensely colored dry red wines of excellent class, as well as high-quality sparkling wines, dessert, sweet and liqueur wines; suitable for the manufacture of high-quality strong colored juices. When used in blends with other varieties enhances color, full flavor and enhances the bouquet of the wine
The article presents data on the formation of the embryonic fruitfulness of central buds of wintering buds grapes of different origins in the period of relative calm of grapes and early spring period in dynamics with presence of positive air and soil temperatures
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
The article gives an overview of the results of studies on indigenous grape varieties of the Republic of Abkhazia and the identification of their agro-biological characteristics
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
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
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
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 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
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
