Genetics and Improvement of Fruit and Vegetables

The GAFL unit is developing research on the genetics of fruit and vegetables to contribute to the ecological transition and meet the challenges of adapting horticultural systems to the reduction of synthetic inputs and climate change. The aim is to make genetic diversity a relevant and effective lever for increasing the capacity of fruit and vegetables to maintain quality production in the face of biotic and abiotic stresses in agro-ecological systems, in synergy with complementary technical levers from other disciplines.

The strategy consists in i) targeting the key traits for adapting to biotic and abiotic stresses, ii) identifying sources of resistance, iii) understanding the function of resistance determinants in plant × pest × environment interactions in order to reason gene and QTL associations so as to protect these resistances and ensure their durability.

GAFL ambition is to produce high-level academic knowledge while ensuring that the results are useful, particularly for breeders. The unit relies on an excellent network of collaborations with the CTIFL and experimental stations, breeding companies and nursery growers.
