Abstract
The ‘Romé’ variety is considered an Andalusian (southern region in Spain) autochthonous black grape cultivar. However, several white and black grapevine accessions are known by this name, according to Vitis International Variety Catalogue. The aim of the present work was to clarify the identity of the ‘Romé’ and ‘Rome Tinto’ as black grapevine cultivar. Eight accessions known as ‘Romé’ and two as ‘Rome Tinto’ were analyzed using 30 OIV descriptors and 22 SSR loci. The morphologic and genetic analysis showed that all accessions studied presented the same genotype and phenotype and grouped with South Spanish cultivars. This study helps to clarify the confusion over the identity of ‘Romé’ grapevine cultivar, and provides a solid basis to develop a germplasm collection to protect grapevine diversity and to recover cultivars that may be in danger of extinction.

The VIVC database (Vitis International Variety Catalogue [VIVC, www.vivc.de]) includes two varieties of Spanish origin called ‘Rome’: a white-berry cultivar (VICV 16035), which only is conserved in two Spanish collections [Finca El Encín (Institute Code VIVC ESP080) and Rancho de la Merced Germplasm Bank (Institute Code VIVC ESP074)], and a black-berry cultivar (VIVC 10181), whose conservation location is unknown
Summary
Grapevine (Vitis vinifera L.) is a species that presents a wide genetic diversity and is widely conserved in germplasm banks. In order to clarify the misidentification and confusion in grapevine variety designations caused by the morphological characterization subjectivity, many collections have already been characterized using Sample Sequence Repeats (SSR) markers (Lopes et al, 1999; Martín et al, 2003, 2011; Ortiz et al, 2004; De Mattia et al, 2007; Dzhambazova et al, 2009; Ibáñez et al, 2009; Vargas et al, 2009; Cipriani et al, 2010; Laucou et al, 2011; Lacombe et al, 2013; MillaTapia et al, 2013; Aliquó et al, 2017) This problematic is collected in The Vitis International Variety Catalogue (VIVC, www.vivc.de), which is currently the source of reference to help group the varieties under a common and consensual identifying label (Lacombe et al, 2011). This European database includes a variety with the prime name ‘Rome Tinto’ (VIVC 40905) that only is conserved in the Rancho de la Merced and its origin is uncertain
