Abstract


Twenty-one grapevine varieties grown all over Greece and belonging to Mavroudia group were ampelographically described and genotyped by AFLP molecular analysis in order to discriminate the varieties, synonyms, homonyms and variations of the group. In most cases, the molecular findings confirmed the results of the ampelographic description. In general, and despite the high degree of genetic similarity between certain pairs of the studied cultivars, the group of Mavroudia was characterized as being heterogeneous. From the studied cultivars, Kountoura mavri, Mavro Spetson and Pappoudes showed very high degree of genetic similarity, sustaining the hypothesis that the last two are clones of the first. Grapevine cultivar Pappoudes was for the first time ampelographically described and identified as being closely related to Kountoura mavri. High degree of genetic similarity was observed between cultivars Gaidouricha and Agiomavritiko, suggesting that they probably originated from the same parent variety through the accumulation of mutations. This may also be true for cultivars Mavrokorakas and Kartsiotis. Also, the results from the statistical analysis showed that Mavro Arachovis, Mavroudi Voulgarias and Voulgaroudes, despite the relatively high genetic similarity between them, are different. The same applies for the rest of the cultivars studied, while Mavro Kalavriton, the most widespread variety of the Mavroudia group, showed the lowest degree of genetic similarity within the all the cultivars studied. The ampelographic description in combination with the molecular method AFLP are effective for the study of the between and within genetic diversity of grapevine cultivars as well as for their identification and discrimination.
