A variety determines the direction of use of grape
products and plays a leading role in improving its
quality. Preservation of genetic resources of grapes
and their studying are very important for modern
science. The studied material makes it possible to use
the selected genetic characteristics for breeding new
varieties of grapes, taking into account the
requirements, and introducing them into production, as
well as highlighting the most valuable varieties for
transferring them to the state variety testing. Among a
wide variety of grape varieties, in the ampelographic
collection there are varieties of AZOSVIV selection of
the technical direction: Krasnostop AZOS and
Dostoiniy, for which complete phenotyping was
carried out. The phenological and agrobiological
information on the grape varieties studied for 2015-
2017 is collected. The presented grades of grapes of
the technical direction are characterized by high
quality of production. The wines from the varieties
Krasnostop AZOS and Dostoiniy are competitive,
characterized with high consumer properties; they
enjoy the well-deserved fame and were nominees of
exhibitions and holders of diplomas repeatedly. Based
on the results of microsatellite profiling, the varieties
showed a sort-specific general combination of alleles.
At the same time, in each locus there is one identical allele, which corresponds to the fact that the varieties
Krasnostop AZOS and Dostoiniy have one common
parent (Phylloxer-resistant Gemete). The received
formulas of a variety (DNA-passports) in practice can
be effectively applied to determine the cleanliness of
planting stock and plantations of grapes, specification
of the parent forms of the sample and in the disputed
questions of the authorship of the variety. The study
was supported by Federal Agency for Scientific
Organizations program for support the bioresource
collections
In the world, huge work is being done to create global
information banks of plant genetic resources. The need
for conservation and rational use of genetic resources
in modern conditions has become very relevant.
Genetic collections are the basis for selection work:
creating new varieties, replenishing the assortment
with new, classic, introduced and native varieties,
adapted to the natural (soil and climatic) conditions of
the cultivation sites. In the Anapa ampelographic
collection, 4911 varieties of various ecogeographical
and genetic origin are represented, the use of which
provides great opportunities for creating and breeding
new varieties, their state testing and zoning. In the
gene pool of the ampelographic collection, most
varieties of V. vinifera L. grapes are represented by
local honeycombs of different regions of the grape
culture, and more than one fourth of varieties of V.
vinifera L. are obtained from intraspecific crossings.
Despite the value of local varieties of grapes, they do
not always meet all the requirements of production.
Therefore, to improve the local assortment, it is
necessary to carry out selection - breeding new
varieties of grapes. This article presents the long-term
results of the work on the selection of varieties of table
and technical directions in the Anapa ampelographic
collection used for breeding. Also, the role of the
genetic collection in the creation of new generation
varieties by combinative selection is shown - as
donors for creating new varieties of grapes. Dedicated
varieties are the sources of valuable traits, which are given primary importance and are especially important
for the viticulture of the Russian Federation
