Many studies highlight a positive effect of species diversity on plant community productivity and associated biodiversity. But genetic diversity effect on species community is still poorly studied despite the rare studies showing a positive effect with prospects for application in the field of plant breeding. It is in this context that this thesis examines the genetic diversity effect on grassland communities and associated soil biodiversity. This thesis is based on a real situation via an evaluation design of grassland mixtures installed by and in a plants breeding company. The major results of this thesis are a positive effect of the species genetic diversity on mixture biomass production, especially during drought episodes, and on specie...
