Guinea yams (Dioscorea cayenensis-rotundata complex; D. rotundata Poir. and D. cayenensis Lam.) have been described as resulting from a process of domestication of wild yams of the section Enantiophyllum by African farmers. Although currently practised by few farmers, the process of yam domestica...

A better knowledge of traditional cultivars is a prerequisite to overcoming the various constraints of yam production in Benin. Using IPGRI's descriptors, 560 accessions of cultivated yams (D. cayenensis Lam./D. rotundata Poir. complex) collected throughout Benin, were characterised. Ninety morph...

Based upon IBPGR (IPGRI) morphologic descriptors, 560 accessions of Benin Republic's cultivated yams (Dioscorea ccayenensis/Dioscorea rotundata complex were morphologically characterized. Ninety morphotypes were identified and accessions were classified into 26 varietal groups according to their ...

The main goal of this study is to gain insight into the relationship between the genetic profile of cultivated rice (Oryza spp.) accessions and their resistance to rice blast. Therefore, the genetic and phenotypic variability of a set of 350 cultivated rice accessions originating from Africa (Ben...

Background Macrotyloma geocarpum Harms is a neglected and underutilized crop in Benin subject to several constraints including storage insect attacks, which contribute to the decrease in its production. An ethnobotanical survey using a semi-structured questionnaire was conducted in 15 villages in...

Using IPGRI's descriptors, 45 accessions of Guinea yams (Dioscorea cayenensis Lam./ Dioscorea rotundata Poir. complex) collected in Cameroon were classified into six cultivar groups based on their morphological similarities. An identification key is proposed for the cultivar groups. Six enzymatic...

To fully exploit the diversity in African rice germplasm and to broaden the gene pool reliable information on the population genetic diversity and phenotypic characteristics is a prerequisite. In this paper, the population structure and genetic diversity of 42 cultivated African rice (Oryza spp.)...
