In the article the characteristics of 64 perspective grades of grapes which are valuable for production use in southern regions of Russia are resulted. Color images in the form of photos of these grades of grapes are presented in earlier published section 8 of the given collective monograph
In the article the questions of grape plantings spareness elimination by the ways of filling-up saplings with cuttings of scleroticе rods, green arms or a bush and reinoculation of bushes. With the preventive purpose, for reduction of plantings spareness degree on a vineyard, stamping of arms, application of potash fertilizers in the summer and in the autumn, stopping of watering in due time, normal loading of bushes with a crop and harvesting in due time are done, i.e. all the conditions for the best ripening of a rod and preparation of plants for winter are made
Clone selection of usually zoned grades of grapes nowadays is made in all countries of the developed wine growing and this way increases not only productivity level, but also quality of raw materials. Process of clone selection is complicated by long-term finding-out of presence of changes of genotypical grade environment. For simplification of selection of a highly productive protoclone of selected grades use of the advanced methods of genetic marking of pluses-transgressions and selection of nucleotidically changed plants with a complex of high values of valuable quantitative signs is necessary
Vitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection
The Mavrostifo – Greece aboriginal variety. It is belong to the group of varieties convar. pontica subconvar. balcanica Negr. The time of production period is 156-165 days. The variety of medium height. The degree of ripening of vine is higher.
The yield is higher. The average mass of bunch is
360 g. It has higher drought-resistance and middle steadiness for mushrooms diseases.
The leave is large, black-green, the middle dissection, five lobes (the lobes are recovered), from bottom side with a lot of hairs.
There are two blossoms on the 3 and 4 nodes.
The flower is hemofroditus.
The bunch is low or big, long, conical-winged, density. The berry is average, round, black-blue. The pulp is juicy, with tasty variety after taste.
There are two-three seeds in berry.
The sugariness is higher.
The variety is useful for preparing higher quality intensive colored red wines of different categories from southern zones of viticulture with warm and dry climate.
The Patris variety is a hybrid, which was made as the result of Greece-Russian scientific collaboration in Greece by Panteley Zamanidi and Leonid Troshin in 2001 year by hybridization of Aigeorgitiko and Cabernet Sauvignon variety. By its morphological characteristics, it is included to the group of the Black sea varieties (convar. pontica subconvar. balcanica Negr.). The production period is 156-165 days. The growth of shoots is big. The yield is very high. The weight of bunch is 250 g. It has good frost resistance, drought resistance and higher steadiness to mushroom diseases, comparing with the parents varieties of Vitis vinifera L. The leave is middle, black-green, five lobes, deep divided, bubbles on the higher plate are low, the hairs are low on the upper side and intense on the bottom. The flower is hermaphrodite. The bunch is middle, cylinder conical or wrinkle, low density. The berry is middle, round, blue-black color. The skin is dense. The pulp is juicy with paslen taste. The sugariness of juice is high. The variety is used for making dry red wines of outstanding quality
The "Academician Trubilin" breed of grape with the colored pulp and juice is bred in Greece by P.Zamanidi, L.Troshin and L.Maltabar in 2003 by mating of the Greek breed of Armeletusa with French Alikant Bush. Duration of rule-oriented phase is 146-155 days. Productivity is high. The medial mass of racemations is 170 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds of Vitis vinifera L. Flower is bisexual. A racemation is medial, cylindrical with a wing, medial denseness. Bacca is small, roundish, blue-black color, with a dense wax coating. Peel is tight. Pulp and juice are intensely colored, with high quality tang. Sugar content is high. Differs with long preservation of crop on bushes. The breed is designed for production of intensely colored dry red wines of the excellent class, and also for high-grade dessert and sweet wines; it is applicable for making high-grade juice as well
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 sort of Artemis is created as a result of the Greek-Russian scientific creative cooperation, it is breed in Greece P.Zamanidi and L.Troshin in 2003, by mating of the Greek sort of Kondokladi with Traminerom pink introduct. Duration of rule-oriented phase is 146-155 days. Productivity is high. The medial mass of a racemation is 140gr. Differs the raised sustainability to fungous diseases and a drought in comparison with Vitis vinifera sorts. A flower is bisexual. A racemation is small, cylinder-conic, a medial denseness. A bacca is small-medial, circular, greenish-yellow, with a dense wax coating. A peel is tight. Pulp and juice with the expressed high quality flavor. Sugar content is high. The sort of Artemis on morpho-physiological performances is referred to the West European ecological geographical bunch. The sort is designed for production of dry white wines of the excellent class, and also for high-grade dessert and sweet wines; it is applicable for development of high-grade juice, compotes, grape honey as well
In the given and subsequent articles of this scientific electronic magazine scientific works, written by employees of chair of wine growing of Kuban State Agrarian University (in general) , executed for last years, after seven-years-old "Perfection of assortment, manufacture of planting material and grapes: the Collection of scientific articles / КSAU. - Issue 394 (422). - Krasnodar, 2002. - 186 pages" collective results of NIR will be observed
