Abstract:
Drăgăşani is one of the oldest vineyards in Romania. Some of the local cultivars cultivated here were gradually replaced by new Romanian or international cultivars. The paper aims to identify, evaluate and conserve this native genetic resource. Following this process, the old inventory cultivars can be promoted for cultivation in order to restore traditional cultivars or to be used in the amelioration process. The study was conducted for three years in private plantations of 40-90 years old. In the first stage, old genotypes of vines were localized and identified, the coordinates (latitude, longitude and altitude) being retained by GPS. Among the old identified genotypes there are: ‘Crâmpoşie’, ‘Braghină’, ‘Gordan’, ‘Tămâioasă Românească’.
In the second stage, the study focused on biological aspects (how they deal with frost, drought), on phenological and technological aspects (acidity and accumulated carbohydrates). As a result of the study, several elites with agrobiological and productive potential were retained for the purpose of clone selection. Thus, ‘Tămâioasă Românească’ is recommended for high quality aromatic wines with a controlled designation of origin; ‘Crâmpoșie’ is recommended for the production of white wines of superior quality with a controlled designation of origin, ‘Braghină’ and ‘Gordan’, for superior wines, with a controlled designation of origin or with protected geographical indication.
Also, the four cultivars reunited in percentages of 10, 30, 30, and 30%, respectively, will be able to rebuild the wine that has previously ensured the fame of the Drăgăşani vineyard.
