Several DNA-based marker systems are available for genetic fingerprinting of plants but information on their relative usefulness for yam germplasm characterisation is lacking. The efficiency of RAPD, AFLP and SSR markers for the assessment of genetic relationships, and for cultivar identification...

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 ...

Anthracnose, caused by Colletotrichum gloeosporioides, is the most severe foliar disease of water yam (Dioscorea alata) worldwide. The tetraploid breeding line, TDa 95/00328, is a source of dominant genetic resistance to the moderately virulent fast growing salmon (FGS) strain of C. gloeosporioid...

Resistance to Yam mosaic virus (YMV) in tetraploid white yam (Dioscorea rotundata) is inherited differentially as a dominant and recessive character. Elite D. rotundata breeding lines with durable resistance to YMV can be developed by pyramiding major dominant and recessive genes using marker ass...

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...

Yams (Dioscorea spp.) constitute a staple food crop for over 100 million people in the humid and subhumid tropics. They are polyploid and vegetatively propagated. The Guinea yams, Dioscorea rotundata and D. cayenensis, are the most important yams in West and Central Africa where they are indigeno...
