“…The second branch (B) was split into two clusters. Cluster C-IV grouped CINSAUT NERO and OTTAVIANELLO, which are considered synonymous based on ampelographic traits [9]. Finally, PINOT NOIR and PINOT BLANC, strongly related with UVA SAN PIETRO, were grouped in C-V.…”

“…In previous studies, a limited number of Apulian ancient grapevines was characterized by using SSR markers, thus unveiling putative cases of synonymy and the relationships between Apulian and national/international varieties [8,9,68]. Herein, a larger panel of 84 minor/neglected Apulian grapevines was investigated.…”

“…However, only C-II showed a differentiation from C-IV/V (F ST = 0.127). C-II included the Apulian cultivar Baresana bianca, which is synonymous of many Greek cultivars [9], and another four minor/neglected Apulian grapes, probably closely related to Baresana Bianca, with which they form a separate genetic pool.…”

“…After many years of high yield production of vine grapes suitable for wine blending, Apulia is moving towards a high-quality production. Often it is based on the exploitation of autochthonous varieties, such as Primitivo, Negroamaro, Uva di Troia, Bombino nero, Malvasia nera di Brindisi, which are used to produce PDO and/or PGI wines [8,9].…”

The investigation on the genetic diversity of grapevine germplasm is crucial for a more efficient use of grapevine genetic resources in light of changing environmental conditions. Here, we used simple sequence repeats (SSRs) coupled with single nucleotide polymorphism (SNP) markers to disclose grapevine genetic diversity of a collection of Apulian minor/neglected genotypes. Their relationships with national or international cultivars were also examined. Genetic diversity was investigated using 10 SSR markers and 1,178 SNPs generated by genotyping by sequencing (GBS). Based on the SSR data, the 128 genotypes were classified into six main genetic clusters. Twenty-four putative cases of synonymy and 2 of misnamings were detected. Ten “unknown” autochthonous genotypes did not show high similarity to Apulian, national, or international varieties. We took advantage of available GBS-derived SNP data points for only forty genotypes to better investigate the genetic distance among them, identify private SNP alleles, and divergent loci putatively under selection. Based on SNP alleles, two interesting gene pools of minor/neglected Apulian samples were identified. Genetic divergence was investigated by FST and allowed the detection of loci capable of differentiating the gene pools. Overall, this work emphasizes the need for recovering the untapped genetic variability that characterizes minor/neglected grapevine Apulian genotypes and the requirement to preserve and use more efficiently grapevine genetic resources in breeding programs.

“…The breakthrough came along with the recommendation of a consortium of the EU-project GrapeGen06 defining a set of SSR markers for variety identification and the widely use by the grapevine community of at least the nine proposed SSR-markers VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD28, VVMD32, VrZAG62 and VrZAG79 to make genetic profiles comparable [12,13]. These markers proved to be efficient to sort out grapevine collections [14], to identify identical cultivars grown under different names in neighboring countries, indicating cultivar migration over long distances [15][16][17] and to revise official national variety lists [18,19].…”

The establishment of the Vitis International Variety Catalogue (VIVC) dates back to 1984. The idea was to virtually assemble all accessions maintained in the worldwide existing collections to face genetic erosion. In many cases synonymy, homonymy and misnaming hampered the clear assignment of cultivars/accessions to prime names. In the past 15 years nuclear microsatellites, in particular the nine SSR-markers VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD28, VVMD32, VrZAG62 and VrZAG79 were extensively applied for cultivar recognition in combination with ampelography. Genetic fingerprints of more than 15,000 cultivars/accessions were collected. They were taken from more than 300 articles and from microsatellite databases on the web. Allele sizes were adapted according to own internal reference varieties. Comparison of profiles revealed new identities like: "Corbeau" = "Sevilhao", "Gragnelut" = "Fer", "Beretinjak" = "Bianco d'Alessano". The activities aim to equip the prime names of VIVC with reliable genetic profiles combined with the validation of their identity by ampelography. Fingerprints from 1,500 cultivars were already uploaded in VIVC. Two distinct search modules were implemented: "Microsatellites by varieties" and "Microsatellites by profiles". The implementation assists the management of grapevine genetic resources, e.g. trueness to type assessment in grapevine collections and serves research and breeding.
