Genetic architecture of quantitative traits in plant-virus interactions: Consequences for the management of resistant and/or tolerant varieties at the landscape scale

The ArchiV project concerns the study of quantitative resistance and tolerance to pathogens in plants. The biological models consist in economically-important pathogens (Potato virus Y, Cucumber mosaic virus and Phytophthora capsici) in pepper (Capsicum annuum L.).

It aims to measure these two quantitative traits, map the loci responsible for these traits (QTLs) on the pepper genome, and to estimate the durability potential of quantitative resistance and tolerance. It also aims to identify the genetic determinants of pathogenicity traits (load, aggressiveness) of pathogens and their interactions with plant resistance and tolerance QTLs. Modelling approaches will make it possible to define the best strategies for deploying resistance and tolerance in the field (QTL pyramiding, varietal rotations, mosaics or mixtures of varieties).
