Identification and Relationships of Grapevine Cultivars Authorized for Cultivation in Castilla La Mancha (Spain)

Abstract

A frame of reference for the genetic profiles of grapevine cultivars whose cultivation is permitted in Castilla La Mancha (Spain) was established by analyzing 26 nuclear and five chloroplast microsatellite loci. The aim was to validate plant material in such a way as to identify those errors of nomenclature (synonyms and homonyms) that are common in grapevine and that can cause administrative problems and then to search for possible parent-offspring combinations. Results showed no differentiated genetic profile for cv. Verdoncho, which is a synonym of Pardina/Jáen Blanco. The Alarije cv. has a dual legal status, as it coincides genetically with Torrontés. There are also several cases of homonyms affecting the denominations Albillo, Coloraíllo, and Moravia Dulce. Each of these embraces a group of different cultivars, some of which have not been described previously, such as Albillo Dorado. Results confirm the origin of cultivars Albillo Dorado, Coloraíllo, and Moribel from a cross between Tempranillo and Moravia Dulce, with Moravia Dulce the female parent for all.
