Research project: imagining and building the phenotypes of the future

In addition to my responsibilities as head of the SVQV unit, my research aims to generate knowledge that will enable the development of grape varieties suitable for the production of quality wines in a context of climate change.

Wine production is highly sensitive to climatic conditions, and this is reflected in the concept of vintage, which is specific to this crop. On the one hand, anticipating adaptation is crucial because the diffusion of new varieties is a slow process, with a significant time lag compared to the initial crossbreeding, and they are moreover likely to be planted for 25 to 30 years. On the other hand, the evaluation of genotypes for their oenological suitability under real production conditions is a long and costly process: it is essential to have tools that allow rapid and efficient selection for these characteristics, in addition to selection for resistance to fungal diseases. I am coordinating a programme on the genetic determinism of grape quality, taking into account the consequences of climate change. The aim is to understand the genetic basis of the composition of aromas and aroma precursors, sugars and acids in grape varieties, but also to be able to predict how these parameters will evolve in the climatic context of the future. The idea is to provide breeders with genetic profiles (ideotypes) for priority traits to include in variety creation programmes, as well as the molecular tools associated with these traits.
