Heat requirements for grapevine varieties is essential information to adapt plant material in a changing climate

Drought is one of the most challenging threats for viticulture because of its impact on reducing yield and on the composition of grapes.

«Graves de Bordeaux» est une des rares appellations à porter le nom d’un terroir, au sens agronomique du terme. Et ce territoire vitivinicole présente une relative unité géographique, de Langon à Bordeaux sur la rive gauche de la Garonne.

Climate change, with rise in temperatures, is leading to an advance in the dates of phenological stages, with a loss in quality of the grape final product. Therefore, the understanding of the genetic determinants driving the phenological stages of flowering, veraison and the interval between them, represents a target for the development of grapevine’s cultivar adapted to the changing environment.
Here we conducted a GWA study to identify SNPs significantly associated to flowering time, veraison time and to the interval among them. A germplasm collection (CREA-VE in Susegana, Treviso, Italy) including 649 grapevine’s cultivar representing 365 unique genotypes was considered.

The importance of polyphenols, which are present in many vegetables and grapes too, is well-know and documented. Specific research works about the red grape

Precision viticulture consists in using ICT (Information and Communication Technology) to implement more specific and better targeted technical vine practices. With proxy-detection
