To cope with the challenges facing agriculture, speeding-up breeding programs is a worthy endeavor, especially for perennial species such as grapevine, but requires understanding the genetic architecture of target traits. To go beyond the mapping of quantitative trait loci (QTLs) in bi-parental crosses, we exploited a diversity panel of 279 Vitis v...
Article
Geographical distribution and diversity of current plant species have been strongly shaped by climatic oscillations during the Quaternary. Analyzing the resulting divergence among species and differentiation within species is crucial to understand the evolution of taxa like the Vitis genus, which provides very useful genetic resources for grapevine...

Fanleaf virus disease, which was spread on a large scale during post-phylloxera reconstitution, represents today a major concern for most of vineyards worldwide. Without any efficient accessible mean of direct control at the present time, concerning an incurable disease whose nematods vectors are able to survive and remain infectious in the soil fo...

Abstract: Simón de Rojas Clemente y Rubio (1777-1827) is considered the father of modern ampelography. He developed the first scientific method for describing grapevine varieties through the examination of material he himself collected in Andalusia between 1802 and 1804. The Royal Botanical Garden in Madrid conserves the material he collected and p...

Key message The maternal and paternal parentage of 36 rootstocks was determined and verified. The results of this study indicate that existing grape rootstocks are closely related to each other and have a narrow genetic background. Abstract Rootstocks are used to protect grapevines from biotic and abiotic stresses including phylloxera, nematodes,...

The wine industry is facing critical issues due to climate changes since production is established on very tight Genotype × Environment interaction bases. While, some cultivation practices may reduce adverse effects of abiotic stresses on the vines, e.g., the use of irrigation to mitigate drought, the deleterious impacts of warming on fruit develop...

Grapevine is a very important crop species that is mainly cultivated worldwide for fruits, wine and juice. Identification of the genetic bases of performance traits through association mapping studies requires a precise knowledge of the available diversity and how this diversity is structured and varies across the whole genome. An 18k SNP genotypin...

The complete nucleotide sequence of an isolate of grapevine satellite virus (GV-Sat) was determined by next-generation sequencing (NGS) and compared with the single available complete sequence. The NGS data unexpectedly provided evidence for the existence of multimeric forms of GV-Sat, which were experimentally confirmed, allowing the redefinition...

During the 2015 season, ICV Group consultants observed a "chlorophyll defect" (formerly known as "albinos") morphological variation in a parcel of Grenache N that is part of the "Ventoux Observatory" in the South of France. An anomaly of the same type was also reported in the Pyrénées-Orientales for Chardonnay B variety. These manifestations are mo...

We propose here a decision support system for vine growers to assess the quality of a vineyard to be planted. The quality of a vineyard is defined by the probability of possible profitability of the wine sales he is able to produce. The model, based on a Bayesian network (BN), takes into account environment and the parameters defining vineyard stat...

Conference Paper
The current chromosome assembly of the grapevine reference genome is under improvement using two strategies. First several maps have been densified using SNP markers developed both from a classic Sanger re-sequencing of the parents and from the re-sequencing of a panel of diversity in the Vitaceae genome to develop a 18K genotyping chip (http://urg...

Cultivated grapevines, Vitis vinifera subsp. sativa, evolved from their wild relative, V. vinifera subsp. sylvestris. They were domesticated in Central Asia in the absence of the powdery mildew fungus, Erysiphe necator, which is thought to have originated in North America. However, powdery mildew resistance has previously been discovered in two Cen...

Background Grapevine (Vitis vinifera subsp. vinifera) is one of the most important and ancient horticultural plants in the world. Domesticated about 8–10,000 years ago in the Eurasian region, grapevine evolved from its wild relative (V. vinifera subsp. sylvestris) into very diverse and heterozygous cultivated forms. In this work we study grapevine...

Through multiple vegetative propagation cycles, clones accumulate mutations in somatic cells that are at the origin of clonal phenotypic diversity in grape. Clonal diversity provided clones such as Cabernet-Sauvignon N°470, Chardonnay N° 548 and Pinot noir N° 777 which all produce wines of superior quality. The economic impact of clonal selection i...
