06.00.00 Agricultural sciences
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

EXTRACTION OF DNA FROM HERBARIUM LEAVES VITIS VINIFERA L.
06.00.00 Agricultural sciences
Description
Two methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA

THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS
06.00.00 Agricultural sciences
Description
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

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

NOVATION OF VITICULTURE IN RUSSIA 4. DEVELOPMENT OF CLONE SELECTION IN VITICULTURE
06.00.00 Agricultural sciences
Description
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

TECNOLOGY OF CLONE SELECTION WITH THE USE OF MOLECULAR MARKERS
Description
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: Riesling and Pinot. These results become the rationale for the new technology of clone selection, breeding and making registration of these clones of four above-named varieties groups in the varieties-clones for state research: Cabernek, Cabernet Fanogoriisky, Merlok, Pinot white, Rieslinalk, Riesling Anapa and Riesling Fanogoriisky. These varieties-clones are accepted by State commission of Russia, they will enrich the viticulture assortment of Anapa-Tamanskay zone of Kuban, therefore Russia
