In Europe, pulses can contribute to face needs in protein supply for animal feed. Field pea yield stabilization and improvement are essential objectives for geneticists and breeders, which could be reached through the development of autumn-sown varieties, with a longer development cycle than spring peas. However, pea crop development faces several limiting factors, among which biotic (root rot due to Aphanomyces euteiches, ascochyta blight due to Mycosphaerella pinodes) and abiotic (winter frost) stresses. The improvement for the tolerance to frost and for partial resistances to ascochyta blight and to Aphanomyces relies on the knowledge of the variability of sources of resistance, analysis of genetic factors or QTL controlling resistance or tolerance, and use of molecular markers to combine these genetic factors in order to develop efficient and durable resistances. The knowledge of the diversity of these factors, of their stability towards environments and stress variability, and of underlying mechanisms allows to target the choice of the QTL to combine together within breeding programs. The created partially resistant lines will be screened for their adaptation to various environments within field trial networks whose main limiting factors are described, and for the effect of their cropping on the possible adaptation of pathogen populations.
