Autor: Adeniyi, O.J. Adetimirin, V.O. Ingelbrecht, I.L. Asiedu, Robert

In vitro culture media capable of regenerating moderate to high shoots and/or plantlets from meristems of two yam species – Dioscorea rotundata and Dioscorea alata within comparable duration of 10 weeks as commonly obtained in other monocots and root and tuber crops were investigated. The study c...

Studies were made to identify sources of resistance to yam viruses in Dioscorea alata. Forty genotypes of D. alata were evaluated in both the field and in the screenhouse for reactions to the yam viruses: Yam mosaic virus (YMV), genus Potyvirus; Dioscorea alata virus (DAV), genus Potyvirus; Cucum...

Anthracnose and virus diseases exert devastating impacts on yam production in many tropical regions of the world where the crop contributes to food security and income generation. The complexities in their epidemiology necessitate the use of integrated approaches in their management. Six genotype...

Use of genetic resistance is the most practical and economic way to manage major diseases of yams. In a search for sources of resistance, 40 water yam (Dioscorea alata L.) accessions from Benin, Ghana, Nigeria and Puerto Rico were screened under natural disease infection conditions in Ibadan, Nig...

Yam mosaic virus (YMV) causes the most-widespread and economically important viral disease affecting white yam (Dioscorea rotundata) in West Africa. The genetic basis of resistance in white yam to a Nigerian isolate of YMV was investigated in three tetraploid D. rotundata genotypes: TDr 93–1, TDr...

Accurate and timely detection is vital for mitigation of tuber yield losses resulting from yam mosaic virus (YMV) infection on yam, a major food security crop in West Africa. The observation, from our previous studies, that the triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA...
