DEAP - Diversity, Evolution and Adaptation of Populations

Our research aims to manage and enhance the cultivated diversity for the agro-ecological transition. They are based on three methodologies, (i) mechanistic modelling and simulation, (ii) statistical modelling for inference and prediction, and (iii) participatory design and experimentation. Our model species is bread wheat.
