Bénédicte Quilot
Présentation
Je suis chercheuse à INRAE (France), dans l'unité GAFL en Avignon, responsable du groupe travaillant sur les Prunus impliquant 14 personnes permanentes et Directrice adjointe du GAFL. J'ai une formation d'écophysiologiste et de modélisateur, complétée par des compétences de généticien acquises depuis mon doctorat, post-doctorat et travaillant depuis 14 ans dans une unité de génétique. Mes activités de recherche portent sur les stress biotiques et la qualité des fruits dont les maladies de conservation chez les Prunus. Ils sont basés sur la génétique, la biologie végétale et la modélisation. J'ai développé une approche multidisciplinaire innovante impliquant l'écophysiologie, la génétique et la modélisation informatique pour concevoir des vergers de production à faibles intrants. Je suis donc devenue spécialiste de la conception d'idéotypes assistée par modèle. Pour inclure des objectifs de réduction de l'utilisation des pesticides dans cette démarche, j'ai commencé il y a 10 ans à travailler sur la résistance à la moniliniose du pêcher. Mon équipe est reconnue pour ses travaux sur les résistances aux ravageurs et aux maladies (oïdium, puceron vert du pêcher, chancre bactérien…) et se concentre désormais sur l'intégration multi-caractères et développe des géniteurs élites, pour le pêcher, l'abricotier et leurs porte-greffes. Nous préservons, criblons et étudions de grandes ressources génétiques de Prunus, y compris sauvages et apparentées, et utilisons des outils et des approches modernes pour progresser vers le développement de la sélection multi-caractères pour les systèmes de production à faibles intrants (optimisation des schémas et des méthodes de sélection, sélection génomique) et concevons des prototypes pour 'protéger' les résistances et répondre aux sollicitations multiples.
