Description
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.

INNOVATIONS OF VITICULTURE IN RUSSIA. 3. CLONAL SELECTION OF GRAPES
06.00.00 Agricultural sciences
Description
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

INNOVATIONS OF WINE GROWING IN RUSSIA. 23. REPAIR OF VINEYARDS
06.00.00 Agricultural sciences
Description
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

Description
The polymorphism is the diversity of varieties in ampelografy - the presence simultaneous permanent in the population of two or several phenotypic and genotype differing groups of plants of one variety – i.e. clones. In viticulture the isogenic population is usually called “clone” and variety as the total of clones or forms – i.e. it is heterogenic. Polymorphism of varieties has big practical sense, as varieties-clones have the harmonic complementary adaptive ampelocenosis and higher economical effect for production. In the article the polymorphism of two heterogenic population - the group Pinot and Riesling, which are the best specimen of French and German viticulture is described on the phenotypic level of leaves

THE NEWEST WINE WHITE-BERRY FRUITFUL HIGH-GRADE PONTOS GRAPE
06.00.00 Agricultural sciences
Description
The newest wine white-berry fruitful high-grade breed of grape - Pontos is bred in Greece P.Zamanidi and L.Troshin in 2003 by mating of the Greek breed of Sideritis with a breed of Sovignon. Duration of productivity phase is 156-165 days. A breed is tall. A degree of vines ripening is very high. Productivity is very high, 15-16 t/hectares and more. The medial mass of racemations is 390 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds Vitis vinifera. A flower is bisexual. Racemations are big, pencil-point, with medial denseness. Baccas are average, circular, greenish-yellow color, with a dense wax coating. A peel is tight. Pulp and juice with the expressed high quality flavor. Sugar content is high. It dries when over-ripening and stays on bushes. Under morpho-physiological characteristics, it is included in ecological-geographical bunch of breeds of basin of Black sea. The breed is designed for production of dry white wines of the excellent class, and also high-grade sparkling wines; it is applicable for production of high-grade juice and compotes as well

LICOVRISI – NEW WINE VARIETY OF GRAPE WITH WHITE BERRY OF GREECE
06.00.00 Agricultural sciences
Description
The global warming of the planet caused big changes of biological and social-economic character on the continents. It leads to necessity to invent new varieties of grapes, which are having higher adaptation to changes of environment, including practical steadiness for higher summer temperature and drought. The genetic improvement of Greece varieties was made by the methods of combine selection. The variety Likovrisi was made in Athens University of grape by P.Zamanidi and L.Troshin in 2001 by crossing of varieties Savvatiano and Ugni white. It has higher yielding. The productive period is middle-late. The bunch is big, wings, friable. The berry is middle, round, green-yellow. The pulp is juicy, taste is harmonious. The sugar is higher. It has higher warm-drought steadiness and higher stability to mushrooms diseases in compare with it’s parents. The variety is used for making dry white wines of different categories and spirits for cognac, brandy and grape vodka

«PROFESSOR GUZUN» – A NEW GREECE-RUSSIAN HIGH QUALITY PINK BERRY WINE GRAPE VARIETY
06.00.00 Agricultural sciences
Description
The sort of grapes "Professor Guzun" is hybridized, created as a result of the Greek-Russian scientific creative cooperation, is deduced in Greece by Pantelei Zamanidi and Leonid Troshin in 2001 by crossing of grades Moskhofilero and Merlo. Under morphological and physiological characteristics it is included in a group of grades of pool of Black sea (convar. pontica subconvar. balcanica Negr.). Duration of production period is 146-155 days. Growth of arms is strong. Productivity is very high. Average weight of a cluster is 320 gr. The sort is rather winter-hardy and frigostable. It is characterized by higher stability to mildew, oidioum and grey decay in comparison with the Black Sea wine grades. Drought resistance is higher than grades of the West European group The flower is hermaphroditic. Grapes are average size or bigger, conic, average density. A berry of average size, roundish, dark pink color. A peel is tight. Pulp is juicy, with the sort taste. Sugar content is high. The grade is intended for manufacturing of high-quality dry, champagne, strong or dessert wines of different categories

Description
In the given article, innovations of application of Nutrivant-plus spray feeding at Viorika variety vineyards are presented. As a result, it has made more considerable impact on the basic agro biological and technological indicators of a variety, than monokalium phosphate standard fertilizer; it has promoted quantity increase of embryonic inflorescences and their differentiation; stimulated an increase in a weight of a cluster and, as a consequence, increase of a crop from a bush and hectare; considerably accelerated and stimulated process of accumulation of sugars in juice of berries; led to increase in the area of a sheet plate; provided increase of economic efficiency of manufacture of grapes
