Pea, Pisum sativum L. is one of the major legume crops worldwide. However, its yield remains relatively low mainly due to its high susceptibility to stresses. Pea is particularly susceptible to airborne fungal disease such as rust (Uromyces pisi) and powdery mildew (Erysiphe pisi) and to fusarium wilt caused by the soilborne fungal pathogen Fusarium oxysporum. The use of resistant cultivars is ... [Show full abstract] currently the most efficient control approach. However, the existing resistance level introduced in pea cultivars is still insufficient. It is thus crucial to identify and exploit new sources of resistance to these diseases. Identification of molecular markers tightly linked to resistance is also necessary to facilitate and fasten breeding. Therefore a core collection of pea have been selected and phenotype for its response to rust, powdery mildew and fusarium wilt.
