In the article we have studied 55 aboriginal varieties,
collected in the North Caucasus. We have described
allelic diversity and identified four haplotypes. All the
populations were closely related while being examined
using a factor of Nei's genetic distance (Dn), with the
exception of indigenous varieties of Armenia.
Maximum differences have been found between the
Uzbek population and Astrakhan, Turkmenian,
Armenian populations. The most genetically rich were
the population of Don area and Krasnodar region
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 article presents the results of studies of 92
indigenous varieties and 15 wild genotypes by 24
microsatellite markers. As a result a locus database about
germplasm in the collection stored at the Russian
ampelographical collection AZOSViV (Anapa Zone
Experimental Station of Viticulture and winemaking)
was created. During the research of varietal breeding
populations confirmed the validity in the production of
the cultivar of Krasnostop anapsky with obvious changes
in microsatellite sequences as a clone of famous indigenous
Don cultivar Krasnostop Zolotovskii. This clone
was selected in 1953 by prominent agrotechnologist
Zotkin Ivan Ivanovich which is propagated by the
author and his followers, and after a formal registration
submitted to state testing in 2007 in GSK RF, zoned in
the North Caucasus region (number 6) in 2014 year. Sort
-clone Krasnostop anapsky only in the Kuban today
cultivating in 35 hectares. By using molecular genetic
techniques, now clonal selection of vine grapes is reasonably
improving. Recent data collected by us in the
work process, were analyzed a comprehensive manner,
making it possible to draw conclusions about distinctness
of grape varieties. Some clones were studied by DNA
primers, based on retrotransposon sequences
Problems of biometric evaluation of morphological features of clones for identification of variety group Merlo genotypes were considered in the paper.
