Abstract
Genetic erosion has been rapidly expanding worldwide with local cultivars becoming extinct at a fast pace.
Local cultivars constitute important genetic resources due to their genetic variability and are characterized, at the same time, by significant traits such as adaptability to the new-shaped climatic conditions because of climate change, tolerance to biotic and abiotic stress factors etc.
The Greek vineyard and specifically the vineyard of the Peloponnese is considered among the oldest in the world and it has been associated with the production of famous wines.
Due to its larger size, the vineyard of Peloponnese is characterized by varietal richness, since the indigenous grape cultivars are numerous.
The emergence of such cultivars, such as ‘Valaitis’, ‘Mandilaria’, ‘Mavro Arachovis’, ‘Savatiano’, ‘Roditis’, ‘Agiorgitiko’ and others, as well as their preservation is not only imperative as a source of agrobiodiversity but also as a part of cultural heritage.
The above-mentioned grape cultivars were studied by means of the ampelographic description, for which 65 ampelographic descriptors were used and measured following a list of descriptors developed by the International Organization of Vine and Wine, and by means of 6 microsatellite markers (SSR). The results revealed that there is significant varietal richness in the area and the cultivars under study are closely related corroborating the hypothesis of a common origin.
Their identification and classification through the use of the ampelographic description can provide important information regarding their nomenclature as well as their origin.
The above results highlight the irreplaceable role of the ampelographic description in combination with molecular methods when it comes to the discrimination of grape cultivars.
