Ir Oumaima Chetto, chercheure \u00e0 l’UR.APCRG du CRRA Mekn\u00e8s, a anim\u00e9 ce lundi 27 f\u00e9vrier 2023 un s\u00e9minaire interne intitul\u00e9 \u00ab\u00a0Les l\u00e9gumineuses alimentaires,\u00a0entre\u00a0 l’autogamie et l’allogamie :\u00a0Cas des f\u00e8ves au Maroc\u00a0\u00bb devant une trentaine de participantEs; chercheurEs, technicienNEs, doctorantEs et \u00e9tudiants stagiaires.<\/p>\n\n\n\n

Le travail de recherche pr\u00e9sent\u00e9 intervient dans le cadre de l’affinement des strat\u00e9gies de gestion et de valorisation du mat\u00e9riel g\u00e9n\u00e9tique national en statuant sur le cas du Maroc en mati\u00e8re d’autogamie et d’allogamie des f\u00e8ves sachant que la litt\u00e9rature scientifique indique un taux d’allogamie consid\u00e9rablement variable, allant de 4 \u00e0 84% avec une moyenne autour de 30 \u00e0 40%. Cette \u00e9tude a aussi cherch\u00e9 \u00e0 d\u00e9terminer le taux de f\u00e9condation crois\u00e9e, et ce, en conditions naturelles moyennant des vari\u00e9t\u00e9s marocaines. Ce param\u00e8tre est en effet crucial dans le d\u00e9veloppement des vari\u00e9t\u00e9s synth\u00e9tiques habilit\u00e9es \u00e0 pallier au probl\u00e8me d\u2019instabilit\u00e9 des rendements et aptes \u00e0 exprimer le ph\u00e9nom\u00e8ne d\u2019h\u00e9t\u00e9rosis. La pr\u00e9sente \u00e9tude s\u2019est servi des marqueurs g\u00e9n\u00e9tiques, li\u00e9s \u00e0 la couleur du t\u00e9gument de la graine et \u00e0 la taille et la forme de cette derni\u00e8re, dans deux environnements contrast\u00e9s : Douyet et Sidi Allal Tazi.<\/p>\n\n\n\n

Les r\u00e9sultats g\u00e9n\u00e9r\u00e9s peuvent servir de base au programme ult\u00e9rieur de cr\u00e9ation de vari\u00e9t\u00e9s \u00e0 pollinisation libre et aux \u00e9tudes relatives aux changements climatiques notamment l\u2019\u00e9volution de l\u2019abondance des pollinisateurs dans le temps et dans l\u2019espace.<\/p>\n\n\n\n
