Abstract Identifying the genetic determinants underlying plant-plant interactions is key for understanding plant community dynamics, both in natural and agronomical systems. This report unveils complex architecture of interaction effects on aerial biomass septoria tritici blotch severity varietal mixtures wheat, using co-genome-wide association study. Fifty-four significant allelic between distinct loci were identified, with half involving hub loci. Some inter-individual epistasis might be related to shade-avoidance syndrome. Our results underscore critical role shaping phenotypes offering new perspectives optimize mixtures.
