As part of a trend towards diversification of cultivated areas, varietal mixtures are experiencing a revival of interest in agriculture. Varietal mixtures are particularly at the origin of a higher production, a reduction of chemical inputs and improve the sustainability of our agricultural system. Moreover, they allow a better management of diseases. In addition to the epidemiological effects of varietal mixtures on the spread of pathogens, little is known about the effect of intraspecific interactions between plants and their impact on plant responses to pathogens. In this thesis, rice or durum wheat genotypes from different populations with different selection histories were grown with different conspecific neighbors. In total, more than...
