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 clone selection has very outstanding position behind the actual problems of modern viticulture in the world and in our country. This problem usually has the primary importance behind the scientist who works with grape in all the countries such as USA, German, French, Spain, Italy, Hungary, Bulgaria, Moldavia, Ukraine and etc. In our country last years some positions becomes solving in the plane of scientific research work. Consequently, in the article the history and the situation of clone selection of grape on the Eurasian continent is widely covered.
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
Problems of biometric evaluation of morphological features of clones for identification of variety group Merlo genotypes were considered in the paper.
