MAGE : Modelling and Analysis of Genotype x Environment interactions


We aim at identifying traits and alleles which can give comparative advantages (crop production, yield stability and resilience, environmental balance, ecosystem services, …) under climatic scenarios affected by climate changes including periods of drought and high temperature, different cropping systems and management practices.

The strategy of MAGE is based on the fact that each genotypic trait/allele associated with tolerance to any constraint can have positive or negative consequences on crop production, depending on the environmental scenario and management practices (G x E x M).

In this context, MAGE adopts an innovative approach at the confluence of quantitative genetics, ecophysiological dissection, high throughput phenotyping, and plant modelling.

1) Analyse the time courses of expansion rates (leaf, maize silks, whole plant shoot, …), tillering, reproductive abortion, transpiration, under contrasted environmental scenarios of water deficit, evaporative demand, CO2 and light, and develop models at the process scale.

2) We analyse the genetic variability and the set of constraints and genetic correlations between traits defining the set of possibilities of responses to abiotic constraints in cereal species. MAGE drives networks of field experiments and phenotyping in high throughput phenotyping platforms (M3P) in maize and wheat, for diversity panels and new genetic diversity currently locked into maladapted maize material. We analyse the genetic controls of these parameters/traits by quantitative genetics.

3) We develop crop models (SiriusQuality for wheat and Sirius maize) including in order to analyse the consequences of the genetic variability on crop production in diverse scenarios.
