Mignouna, H.D.Abang, Mathew M.Asiedu, RobertGeeta, R.[Yam (Dioscorea) husbandry: cultivating yams in the field or greenhouse]Yam (Dioscorea) husbandry: cultivating yams in the field or greenhouse

Reliable characterization of the variation among wild and cultivated yams in Nigeria is essential for improved management and efficient utilization of yam genetic resources. RAPD and double stringency PCR (DS-PCR) analyses were used to investigate genetic relationships and the extent of redundanc...


Mignouna, H.Abang, Mathew M.Wanyera, N.Chikaleke, V.Asiedu, RobertThottappilly, G.[PCR markerbased analysis of wild and cultivated yams (Dioscorea spp.)in Nigeria: genetic relationships and implication for ex situ conservation]PCR markerbased analysis of wild and cultivated yams (Dioscorea spp.)in Nigeria: genetic relationships and implication for ex situ conservation

Isolates of Colletotrichum gloeosporioides obtained from yam-based cropping systems in Nigeria, previously characterized on the basis of morphology, virulence and rDNA internal transcribed spacer (ITS) sequence variation were further compared for vegetative compatibility (VC). Chlorate-resistant ...


Abang, Mathew M.Hoffmann, P.Winter, S.Green, K.R.Wolf, G.A.[Vegetative compatibility among isolates of Colletotrichum gloeosporioides from yam (Dioscorea spp.) in Nigeria]Vegetative compatibility among isolates of Colletotrichum gloeosporioides from yam (Dioscorea spp.) in Nigeria

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...


Abang, Mathew M.Winter, S.Mignouna, H.D.Green, K.R.Asiedu, Robert[Molecular taxonomic, epidemiological and population genetic approaches to understanding yam anthracnose disease]Molecular taxonomic, epidemiological and population genetic approaches to understanding yam anthracnose disease

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...
