The grapevine germplasm bank EVEGA contains 135 accessions of 15 Galician cultivars. Analysis with 33 polymorphic microsatellites (SSRs) indicate that Albariño and Loureira could be related to the Caíño group in western Galicia, Spain. Likelihood ratios support the hypothesis of significant parentage relationship between Albariño and Caíño Bravo as parents of Caíño Blanco. Loureira shared alleles for each locus with Caíño Bravo, indicating close relationship by hybridization. Caíño Bravo was related directly with four cultivars (Caíño Blanco, Caíño Longo, Castañal, and Loureira) and with two others (Caíño Redondo1 and Sousón), with which it shared 32 of 33 loci, indicating that it could be the origin of this lineage, as the key cultivar of the Caíño group.
