New findings and actions in the recovery of old Mediterranean grapevine varieties

In this work, we report new findings related to the recovery of grapevine diversity in the Comunitat Valenciana (Eastern Spain): accessions of old varieties at risk of disappearance, new genotypes, synonymies, homonymies, and some foreign old varieties. In addition, the in vitro establishment of some rescued varieties has been carried out as a complement to ex-situ conservation, as well as to provide material for bio-technological applications.
