In our study we have considered three of the most valuable Romanian red wine grapevine cultivars: Feteasca neagra,
Feteasca alba and Novac. We have chosen to study grapevine because grapes and wine are an important part of a healthy
diet, and because red grapes have the highest content of proanthocyanidins, that act as antioxidants (free radical
scavengers) in the human body. Proanthocyanidins possess
anti-mutagenic, anti-tumor, anti-viral activities and they
present many other confirmed or potential benefits. Genotyping method was applied in order to asses the genetic profile
at 14 microsatellite loci, for two cultivars: Feteasca neagra and Feteasca alba. In order to achieve this, the HPLC-DAD
method was used. The content of anthocyans in grape skin from two cultivars - Feteasca neagra and Novac - was
measured. Microsatellite markers have been certified as powerful tools for assessing genetic identities and genetic
relationships between grapevine gene pools. Genetic characterization of grapevine cultivars can certify their authenticity
and purity, two features that have a direct effect on the quality and value of the finished product, the wine. In our
country, this is the first attempt in order to establish a genetic profile for valuable Romanian origin grapevine varieties.
In some of the 14 microsatellitic loci, Feteasca neagra and Feteasca alba cultivars presented allele size variants different
from the values cited in the literature, proving that these cultivars belong to a geographical distinct gene pool. The
content of anthocyans in Feteasca neagra grape skin was significantly higher than in Novac.
