Dry pea is an economically important crop in Europe, for its protein value in animal feed and its environmental value in cereal rotations. The development of the pea crop has been hampered by several limiting factors, among which two main fungal diseases, Aphanomyces root rot due to Aphanomyces euteiches and ascochyta blight due to Didymella pinodes. Plant breeding for quantitative partial resistance to both diseases is a high priority for the sustainable development of control methods integrating resistant varieties as an essential component. This manuscript draws up a synthetic state of current knowledge about i)- the diversity of genetic factors controlling quantitative resistance to A. euteiches and D. pinodes depending on the variability and components of epidemic development of the two pathogens, ii)- the stability of resistance QTL effects depending on environments and genetic backgrounds and iii)- the conservation level of Aphanomyces resistance loci between the pea and Medicago truncatula genomes for approaching resistance QTL functions. The manuscript describes pea germplasm breeding programs integrating the genetic resistances studied, for supporting breeding of pea varieties, as well as future QTL pyramiding strategies for the development of efficient and durable resistances to both diseases in pea.
