Diversity, Adaptation and Breeding of Grapevine (DAAV)

Context and goals

Last update: 19 March 2014

Our team ultimately aims at contributing to the creation of grapevine varieties more resistant to diseases and better adapted to climate changes, while maintaining a high quality level.

Grapevine Vitis vinifera L. is a species of major interest in France where it is grown on approximately 800 000 ha, the wine industry showing a positive trade  balance of 9.5 billions € (in 2012). Vineyards have a large impact on the environment, notably via the intensive usage of pesticides. Wine making also links intimately  to human societies, through the notion of terroir as well as its frequent location around cities. Due to all these aspects as well as to the potential threats on wine quality due to climate change, viticulture has to adapt. A mid-term answer would consist in diffusing new varieties resistant to diseases and better adapted to a changing environment while maintaining a high quality level.

Grapevine is a perennial, diploid species, characterized by vegetative multiplication, high heterozygozity and short linkage disequilibrium.

In this context, our research follows three axes:

  1. the study of diversity and evolution of grapevine and related species;
  2. the identification of the genetic and molecular bases of traits of interest;
  3. the integration of all this information for traits prediction and the breeding of new varieties.

These research themes involve knowledge from various disciplines, such as ampelography, population genetics, quantitative genetics, physiology and phyto-pathology, as well as methodological skills, such as molecular biology, statistical modeling and algorithmics. Furthermore, in the framework of our applied research, we built a joint technological unit, Géno-Vigne®, in partnership with the Institut Français de la Vigne et du Vin (IFV) and Montpellier SupAgro, allowing us to interact with professionals.

To carry out our projects, we are actively involved in the management of the world largest genetic collection for grapevine (Vassal), as well as of various other resources (experimental plots, greenhouses, growth rooms). We master the production technique of “dwarf” grapevines. We benefit from a privileged access to genotyping facilities in AGAP as well as computer clusters from the SouthGreen and URGI bioinformatics platforms.
