“…In this work, the array was validated on 70 genotypes of a grapevine rootstock core collection, obtaining a final dataset of 14,180 SNP loci. This number of SNP loci was in line with the ones reported for V. vinifera germplasm, ranging from 10,041 to 16,501 SNPs [23,24,26,31,[33][34][35], resulting in an informative tool for grapevine rootstock genetic characterization. Among the core collection genotypes with a known pedigree [19], the species mostly represented are V. riparia (29 genotypes), V. berlandieri (16), V. rupestris (11), and V. vinifera (10).…”

“…So far, SSR markers were one of the most reliable and robust tool used for the genetic characterization of vinifera and non-vinifera germplasm, widely adopted for their high degree of information provided by the large number of detected alleles per locus [8][9][10][11][12][13][14][15][16][17][18][19][20]. Recently, SNP (Single Nucleotide Polymorphism) markers have rapidly gained high popularity in the scene of V. vinifera molecular genetics [10,[21][22][23][24][25][26]. The number of SNP loci used to study the genetic diversity increased as the technologies to detect them in the genome changed.…”

“…In this project, a total of 18,071 SNPs were selected, a third of which (4510 SNPs) identified in the Northern American species genome [24]. Several studies validated the 18k SNP set for the evaluation of genetic diversity in V. vinifera [19,23,24,26,[31][32][33][34], but the Vitis18kSNP array could also represent a potentially effective tool for rootstock characterization, due to the consistent number of SNPs detected in the Northern American species genome.…”

Single nucleotide polymorphism (SNP) genotyping arrays are powerful tools to measure the level of genetic polymorphism within a population. The coming of next-generation sequencing technologies led to identifying thousands and millions of SNP loci useful in assessing the genetic diversity. The Vitis genotyping array, containing 18k SNP loci, has been developed and used to detect genetic diversity of Vitis vinifera germplasm. So far, this array was not validated on non-vinifera genotypes used as grapevine rootstocks. In this work, a core collection of 70 grapevine rootstocks, composed of individuals belonging to Vitis species not commonly used in the breeding programs, was genotyped using the 18k SNP genotyping array. SNP results were compared to the established SSR (Simple Sequence Repeat) markers in terms of heterozygosity and genetic structure of the core collection. Genotyping array has proved to be a valuable tool for genotyping of grapevine rootstocks, with more than 90% of SNPs successfully amplified. Structure analysis detected a high degree of admixed genotypes, supported by the complex genetic background of non-vinifera germplasm. Moreover, SNPs clearly differentiated non-vinifera and vinifera germplasm. These results represent a first step in studying the genetic diversity of non-conventional breeding material that will be used to select rootstocks with high tolerance to limiting environmental conditions.

“…The two rose oxide isomers are pleasant volatiles associated with a very low threshold of perception (Table 1). Both of them were only detected in MO, thus supporting a sensory (Fontana, 2014) and a genetic similarity (Ruffa et al, 2016) between MO and White Muscat. Unlike aromatic Malvasia grapes, White Muscat is a variety characterised by both a prevalence of linalool and its derivatives (Ribéreau-Gayon et al, 1975;Di Stefano & Corino, 1984;Palomo al., 2006) and the presence of rose oxide isomers (Ruiz-García et al, 2014).…”

“…Known at least since the 19th century in Emilia (Northern Italy), MO is currently on the brink of extinction because of its low productivity, and it has often been replaced in vineyards by the higher yielding MC (Bignami et al, 2015). A recent genetic study (Ruffa et al, 2016) describes a parent-offspring relationship between MO and MC, as well as between MO and White Muscat (Moscato bianco). At the same time, no genetic relationship has been observed between MC and White Muscat.…”

Malvasia odorosissima is an aromatic grapevine (Vitis vinifera L., 1753) variety that is often confused with Malvasia di Candia aromatica (Vitis vinifera L., 1753), despite the genetic information now available on the pedigree and genetic relationships linking the two varieties. In an effort to offer a contribution to fill this gap, also from an aromatic point of view, free and glycosylated aroma compounds were determined using the SPE extraction method, followed by GC-MS analysis in two consecutive vintages. The results have for the first time provided the aromatic characterisation of Malvasia odorosissima. Geraniol and its derivatives were the most abundant set of volatiles. In contrast to Malvasia di Candia aromatica and the other aromatic varieties, Malvasia odorosissima showed a very small amount of glycosylated volatiles, thus expressing its aromatic potential almost completely. The abundance of free terpenoids in the aromatic profile of Malvasia odorosissima, even higher than in Malvasia di Candia aromatica, is a main feature for the oenological exploitation of this variety, which is on the brink of extinction. In addition, the presence of rose oxides, found solely in Malvasia odorosissima, renders its aromatic profile more similar to that of White Muscat. This result is consistent with the parent-offspring relationship linking the two varieties that was recently ascertained.

A high-density integrated map for grapevine based on three mapping populations genotyped by the Vitis18K SNP chip

et al. 2022

Key message We present a high-density integrated map for grapevine, allowing refinement and improved understanding of the grapevine genome, while demonstrating the applicability of the Vitis18K SNP chip for linkage mapping. Abstract The improvement of grapevine through biotechnology requires identification of the molecular bases of target traits by studying marker-trait associations. The Vitis18K SNP chip provides a useful genotyping tool for genome-wide marker analysis. Most linkage maps are based on single mapping populations, but an integrated map can increase marker density and show order conservation. Here we present an integrated map based on three mapping populations. The parents consist of the well-known wine cultivars ‘Cabernet Sauvignon’, ‘Corvina’ and ‘Rhine Riesling’, the lesser-known wine variety ‘Deckrot’, and a table grape selection, G1-7720. Three high-density population maps with an average inter-locus gap ranging from 0.74 to 0.99 cM were developed. These maps show high correlations (0.9965–0.9971) with the reference assembly, containing only 93 markers with large order discrepancies compared to expected physical positions, of which a third is consistent across multiple populations. Moreover, the genetic data aid the further refinement of the grapevine genome assembly, by anchoring 104 yet unanchored scaffolds. From these population maps, an integrated map was constructed which includes 6697 molecular markers and reduces the inter-locus gap distance to 0.60 cM, resulting in the densest integrated map for grapevine thus far. A small number of discrepancies, mainly of short distance, involve 88 markers that remain conflictual across maps. The integrated map shows similar collinearity to the reference assembly (0.9974) as the single maps. This high-density map increases our understanding of the grapevine genome and provides a useful tool for its further characterization and the dissection of complex traits.
