Abstract
A prospecting work at the Axarquia region (Malaga, Spain) was carried out in order to identify local red grapevine cultivars preserved in ancient vineyards. A total of 11 accessions were collected in seven different plots from four municipalities and analyzed using 25 microsatellite loci for cultivar identification. The accessions analyzed were identified as eight different genotypes, seven of them corresponding to known cultivars as ‘Cabernet Sauvignon’, ‘Jaen Tinto’, ‘Molinera’, ‘Monastrell’, ‘Muscat of Alexandria’, ‘Parrel’, and ‘Romé’. In addition, one of them is referred to as the new genotype for ‘Cabriel’ cultivar. Additionally, an ampelographic characterization was carried out with 30 International Organisation of Vine and Wine (OIV) descriptors for two consecutive years for the eight accessions identified as local cultivars. This allowed the identification of a somatic variant of the ‘Muscat of Alexandria’ cultivar that affects the color of the berry and another of ‘Romé’ regarding bunch compactness.
Highlights
Within the province of Malaga, the Axarquia region is a historically recognized wine territory in Andalusia (Spain)
The main objective of the present study is the identification of red grapevine cultivars grown in ancient vineyards in the region of the Axarquia (Malaga, Spain)
In order to confirm the identified cultivars based on the molecular results obtained, ampelographic observations were made in the vineyard over two years
Summary
Within the province of Malaga, the Axarquia region is a historically recognized wine territory in Andalusia (Spain). The difficult mechanization of the vineyard, the predominance of small vineyard plots, and the low productivity have contributed to vineyard forgetfulness, and nowadays this sector remains rooted in time. Such vineyards may preserve unidentified indigenous or local varieties, which may be of interest in the current viticulture. In this respect, studying their adaptation to warm climatic conditions and their oenological potential to produce new wines could play an important role in the future [3,4]. Nowadays many wine consumers demand new products, with greater diversification and personality; therein lies the growing interest of producers and consumers in ancient local cultivars [5,6]
