Abstract

The use of Single Nucleotide Polymorphism (SNP) markers allows genetic identification and parentage analysis of grapevine cultivars. Ancient cultivars like 'Hebén' were widely cultivated in the Iberian Peninsula along its history and likely contributed to the origin of varieties which are still cultivated today. The goal of our study was to search for possible first-degree relationships between the female variety 'Hebén' and other Iberian and Mediterranean cultivars. For this purpose, we used a set of 261 SNP markers which allowed identifying 23 trios and 37 parent-offspring relationships supported by high overall likelihood ratios (LOD scores). The results shed light on the relationships among several cultivars from Spain and Portugal, and demonstrated that 'Hebén' is a major founder of current varieties in the Iberian Peninsula viticulture, and contributed to spread the chlorotype A in this region.
