A collection of 317 table-grape accessions preserved in the Vitis Germplasm Bank at the Rancho de la Merced (IFAPA, Jerez de la Frontera, Spain) were genotyped at 20 microsatellite loci. A total of 264 different genotypes were obtained. Among them, 66 are presented for the first time. Twenty-one accession names are considered new synonyms, fourteen homonyms and 48 can be considered as "denomination mistakes" in the Rancho de la Merced collection.
