The domestication of wild yams is still common practice in West Africa. It also offers one of the few remaining opportunities to understand how farmers use their empirical knowledge to tap the genetic resources of wild plants and create products suitable for agriculture. Yam agronomists and breed...

Collecte des ignames cultivees du complexe Dioscorea cayenensisrotundata au Benin
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...

Morphological diversity, cultivar groups and possible descent in the cultivated yams (Dioscorea cayenensis/D. rotundata) complex in Benin Republic
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 ...
Four hundred and sixty-seven accessions of cultivated Guinea yam (Dioscorea cayenensis/Dioscorea rotundatacomplex) collected from different localities of Benin Republic were analysed to study isoenzymatic variability in seven enzyme systems: aspartate aminotransferase (AAT), esterase (EST), gluco...

Using isozyme polymorphism to assess genetic variation within cultivated yams (Dioscorea cayenensis/Dioscorea rotundata complex) of the Republic of Benin
DNA from twenty-three late maturing cultivars of Guinea yams (D. cayenensis/D. rotundata complex) from the Benin Republic that could not be separated using isozyme markers, were examined using randomly amplified polymorphic DNA (RAPD) markers with decamer primers of arbitrary sequence. All the tw...
