La production du haricot commun (Phaseolus vulgaris L.) est limite par des contraintes biotiques et abiotiques. Son amlioration requiert l'exploitation de la biodiversit disponible. Lespce P. coccineus L. manifeste des rsistances aux maladies et ravageurs par rapport P. vulgaris. Des avortements massifs dembryons hybrides sont frquents entre 5 et 6 jours aprs la pollinisation (JAP) lorsque P. coccineus est pollinis par P. vulgaris. L'hybridation rciproque russit mieux, mais avec un retour rapide vers le parent maternel. Des coupes histologiques ralises en rsine HEMA sur des embryons parentaux et hybrides, gs de 3 14 JAP, ont permis de suivre la dynamique de l'embryogense pour identifier les causes d'avortement d'embryons et expliquer l'incompatibilit postzygotique entre P. coccineus (?) et P. vulgaris. Les signes d'avortement d'embryons hybrides concernent entre autres le retard de rsorption du nucelle, l'absence de cellules de transfert au voisinage de l'embryon, le retard de la division de l'albumen ou du dveloppement de l'embryon, l'hypertrophie du suspenseur, l'tranglement de la jonction entre le suspenseur et l'embryon et les dfauts cotyldonaires.
