Description

In France, viticulture is a major consumer of plant protection products (PPPs), mainly to control mildew and powdery mildew. But the heavy use of PPPs must be drastically reduced because of their high economic and environmental cost. Climate change is another important challenge wine growers have to face in the future. An effective way to achieve a significant reduction in the use of PPPs is to create new varieties with durable resistance against the most important grape pathogens. Through the ResDur program, INRA has provided the demonstration that this concept is feasible and desirable by releasing the first four varieties with polygenic disease resistance. To accelerate the creation of new disease resistant varieties adapted to climate change and regional conditions, we propose in this project to incorporate genomic and phenomic selection into the current regional breeding schemes for a wider and faster deployment of new varieties.
