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...

Striga hermonthica (del) Benth is threatening rural livelihoods in western Kenya where maize is the major food and cash crop. Vulnerability analysis was conducted on a sample of 802 households in eight districts of Nyanza and Western provinces. Farmers perceived Striga as the major cause of pover...

Water yam (Dioscorea alata L.) is the most widely cultivated yam species globally. The major limitation to the profitable and sustainable production of D. alata is its susceptibility to anthracnose disease. The availability of resistant varieties could potentially form the cornerstone of an integ...

This protocol describes how to produce yam (Dioscorea) seeds through controlled pollination of flowers on female plants. Pollination by flower thrips takes place naturally in normal yam-growing environments in the presence of flowering male and female genotypes, although it is not efficient. This...

Knowledge of the genetic relationships and variability among cultivated germplasm is important for facilitating the transfer of useful genes and maximizing the use of available germplasm resources. In this study, random amplified polymorphic DNA (RAPD) markers were used to assess genetic diversit...

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...

Some 96 accessions of cassava (Manihot esculenta) were evaluted for genetic diversity using random amplified polymorphic DNA (RAPD) primers. Ten out of 80 Primers were considered highly informative and were used to fingerprint all of the accessions. Amplification of genomic DNA with the primers r...
