“…High diversity was found at a morphological level, as only 6 out of 74 ampelographic and ampelometric parameters studied were homogeneous for all varieties. This high morphological diversity has also been reported in other collections (Lamine et al, 2014;Zinelabidine et al, 2014;Khalil et al, 2017;Abiri et al, 2020;Milisǐćet al, 2021). The variation explained by the first three axes of the PCA using ampelographic, ampelometric, and leaf disc test data was low and similar to that obtained by Merkouropoulos et al (2015) in an ampelographic study in a Greek grapevine collection.…”

“…For the remaining 55 accessions included in this study, there was a previous genetic identification through microsatellite markers (SSRs) (Dıáz-Losada et al, 2012; Dıáz- et al, 2013a). This information allowed us to directly assign the existing SSR genotype values with the corresponding SNP profiles already stated by the "Instituto de Ciencias de la Vid y el Vino" (ICVV) DNA database (Cabezas et al, 2011;Cunha et al, 2016; ICVV-DNA database (data non-published); Zinelabidine et al, 2014). SNP data origin for each accession is shown in the last column of Table 1.…”

The genetic erosion of the European grapevine diversity in the last century has promoted the conservation of varieties in germplasm banks to prevent their disappearance. The study of these varieties is necessary as it would allow the diversification of the wine market, as well as provide a source of genes to face new pathogens or climate constraints. In this work, the grapevine varieties preserved in the “Estación de Viticultura e Enoloxía de Galicia” (EVEGA) Germplasm Bank (Ourense, Spain) were widely characterized, combining ampelography, ampelometry, agronomy, and phytopathology. Moreover, genetic characterization was carried out through the analysis of 48 single-nucleotide polymorphisms (SNPs). A Bayesian analysis based on the SNP data was carried out to define the genetic structure of the EVEGA Germplasm Bank, which allowed the differentiation of two main reconstructed panmictic populations (RPPs), confirming previous results obtained based on microsatellite markers (SSRs). A great diversity between varieties was found for almost every parameter evaluated for ampelography, ampelometry, phytopatology, phenology, and berry quality. A principal component analysis (PCA) performed with these phenotypical data allowed discrimination among some groups of varieties included in different genetic populations. This study allowed us to evaluate the grapevine diversity maintained in the EVEGA Germplasm Bank and characterize varieties of potential value for breeding programs of interest for the Galician viticulture.

“…Vitis leaves differ for instance in their degree of lobing, in the lengths and angles of their five major veins and in margin dentation. Ampelographic measurements have therefore been largely used to discriminate between Vitis vinifera cultivars [31][32][33][34][35][36], and more recently Vitis species [37][38][39]. Moreover, Chitwood et al [40] found evidence for an important genetic component determining leaf shape and venation patterning in grape.…”

The grape genus Vitis L. includes the domesticated V. vinifera, which is one of the most important fruit crop, and also close relatives recognized as valuable germplasm resources for improving cultivars. To resolve some standing problems in the species relationships within the Vitis genus we analyzed diversity in a set of 90 accessions comprising most of Vitis species and some putative hybrids. We discovered single nucleotide polymorphisms (SNPs) in SANGER sequences of twelve loci and genotyped accessions at a larger number of SNPs using a previously developed SNP array. Our phylogenic analyses consistently identified: three clades in North America, one in East Asia, and one in Europe corresponding to V. vinifera. Using heterozygosity measurement, haplotype reconstruction and chloroplast markers, we identified the hybrids existing within and between clades. The species relationships were better assessed after discarding these hybrids from analyses. We also studied the relationships between phylogeny and morphological traits and found that several traits significantly correlated with the phylogeny. The American clade that includes important species such as V. riparia and V. rupestris showed a major divergence with all other clades based on both DNA polymorphisms and morphological traits.

“…The first alternative to SSR markers for fingerprinting was a set of 48 single nucleotide polymorphism (SNP) markers [38]. Although this set has been used by other researchers through direct comparison with IMIDRAs database [39,40], the SNP profiles obtained are not publicly accessible, even though they have been proposed for routine fingerprinting. Large grapevine collections have also genotyped their germplasm with SNP markers [20,41,42], and the most comprehensive SNP analysis of grapevine germplasm [43] is result of a large GrapeReSeq consortium that used the Vitis18KSNP chip and, consequently, suggested the use of 14 most informative SNPs for cultivar distinction.…”

Croatian viticulture was most extensive at the beginning of the 20th century, when about 400 varieties were in use. Autochthonous varieties are the result of spontaneous hybridization from the pre-phylloxera era and are still cultivated today on about 35 % of vineyard area, while some exist only in repositories. We present what is the most comprehensive genetic analysis of all major Croatian national repositories, with a large number of microsatellite, or simple sequence repeat (SSR) markers, and it is also the first study to apply single nucleotide polymorphism (SNP) markers. After 212 accessions were fingerprinted, 95 were classified as unique to Croatian germplasm. Genetic diversity of Croatian germplasm is rather high considering its size. SNP markers proved useful for fingerprinting but less informative and practical than SSRs. Analysis of the genetic structure showed that Croatian germplasm is predominantly part of the Balkan grape gene pool. A high number of admixed varieties and synonyms is a consequence of complex pedigrees and migrations. Parentage analysis confirmed 24 full parentages, as well as 113 half-kinships. Unexpectedly, several key genitors could not be detected within the present Croatian germplasm. The low number of reconstructed parentages (19%) points to severe genetic erosion and stresses the importance of germplasm repositories.
