    Research

    Driven by our vision of a world where all people have viable livelihoods supported by healthy and productive landscapes, our global team of science, research, development, institutional and resource professionals seeks to better combine the science of discovery with the science of delivery. To realize this vision, we focus on four key interacting themes: By combining more productive trees with more resilient and profitable agricultural systems and a sounder understanding of the health of the soil, land and people that is part of ‘greener’, better governed landscapes, we offer valuable and timely knowledge products and services to the global community as it tackles the major challenges of the Anthropocene. These include dealing with climate change; low soil carbon; widespread forest, tree and soil loss leading to degradation; poverty; demographic upheavals and conflict; and securing equitable futures for all with a special focus on women and children.

Des missions de collectes ont été organisées dans les principales régions de production du niébé au Sénégal dans le but d’obtenir des informations sur la diversité morphologique et moléculaire au sein des variétés traditionnelles de niébé. Ces missions ont permis de réunir 58 accessions. Deux classifications des accessions collectées basées sur les noms vernaculaires donnés par les paysans et les caractéristiques des graines et des gousses ont révélé respectivement neuf et 18 variétés. Un troisième classement réalisé par rapport aux cultigroupes (cv gr) du niébé a classé une accession dans le cv gr Unguiculata , cinq accessions dans le cv gr Biflora et 52 accessions dans le cv gr Melanophthalmus . L’étu - de moléculaire réalisée sur huit de ces accessions a montré l’existence d’une diversité génétique faible comparée à d’autres cultures. En moyenne 1,31 allè - les par locus avec 22 % de loci polymor - phes et une diversité génétique totale, HT = 0,38, ont été obtenus. 62% de cette diversité se trouvent entre les accessions alors que 38% se rencontrent à l’inté - rieur des accessions. Les flux de gènes entre accessions étudiées ont été faibles : un migrant passe d’une accessions à une autre par génération. La similarité géné - tique entre individus des huit accessions laisse apparaître six groupes d’indivi - dus dont le plus important regroupe cinq accessions identiques. L’étude sem - ble confirmer la localisation du Sénégal dans une zone géographique à forte diversité morphologique du niébé et à faible diversité moléculaire
