| Summary: | [EN] The “Albariño” is one of the most important and interesting cultivars in Galicia (northwest of Spain), however, until the present there were not selected clones of this cultivar. In 1987, in “Consejo Superior de Investigaciones Científicas” prospection of centenary “Albariño” specimens was initiated, in different geographic points in Galicia. Forty centenary “Albariño” specimens were located (source plants) and 11 of them were selected. In 1993, 10 repetitions of each one of the 11 selected plants were grafted, in the collection of the Misión Biológica de Galicia (CSIC). Based on the differences observed among the different source plants, each one of these 11 selected plants, was considered a different clone of “Albariño”. Ampelographic and agronomic variability was studied on the selected 11 clones of “Albariño” cultivar (Vitis vinifera L.). Different ampelographic parameters were measured and observed in green shoot, mature leaf, cluster, berry and seed, on the selected clones according to the OIV's method (1983). The reconstruction of the average leaf was carried out in each one of the clones, according to the Martínez and Grenan's method (1999). Different agronomic parameters were studied: weight of clusters per vine, weight and size of clusters, berries and seeds, number of grapes per cluster, number of seeds in each grape, must yield, probable alcoholic degree, acidity in must etc. There was no significant difference between clones for any of the studied ampelographic parameters, except for two clones (CSIC-1 and CSIC-2) which presented the base of the petiole sinus limited by the nerve. Each one of the 11 clones presented different agronomic characteristics. Some of them varied with a lower weight of clusters per vine, with clusters and berries of small size, and others showed a higher probable alcoholic degree, and high acidity. Finally some of them presented higher size clusters, a high probable alcoholic degree, and a typical level of acidity in Albariño cultivar. |
