Yam mosaic virus (YMV), genus Potyvirus; family Potyviridae is the most important virus infecting Dioscorea spp. in the tropics. It induces a variety of symptoms ranging from mild mosaic on leaves of infected plants to stunted growth. Field and laboratory studies were conducted in Nigeria to iden...

Leaf samples of Lablab purpureus collected from two agroecological zones of Nigeria—the northern guinea savanna zone (NGSZ) and the derived savanna zone (DSZ)—were infected with viruses when serologically indexed against available antisera. Approximately 31.1 and 81.1% of the leaf samples collect...

Nineteen white yam (Dioscorea rotundata Poir.) genotypes were grown in four agroecological zones in Nigeria for 2 years to study their responses to yam virus diseases, and to investigate the influence of genotype × environment (G × E) interactions on their reactions to virus infection, using the ...

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...

The rice yellow mottle diseases is the main virus disease found on rice in Africa. It has been reported in all major rice producing zone of sub-saharan Africa (East,West,Central and Southern Africa and Madagascar). The disease incidence and accompanying yield losses could be high depending on the...

A yam potyvirus was isolated from Dioscorea alata samples collected in Nigeria. The virus was not transmissible mechanically but was transmitted by Aphis craccivora to four cowpea cultivars (Ife Brown, IT84S‐2114, IT82E‐10 and TVu2657), and from which it could be mechanically transmitted between ...

The responses of 24 white yam (Dioscorea rotundata) cultivars to mechanical and vector transmission with each of three viruses infecting yams were assessed through enzyme-linked immunosorbent assay (ELISA) and symptom development. The viruses were Dioscorea alata virus (DAV), genus Potyvirus; Dio...

Seed yam is costly, and can carry pests and diseases. To reduce costs and to manage seed health, in the 1970s, the Yam Minisett Technique (YMT) was developed, which involved cutting yams into small pieces to be used as seed. Few farmers adopted the technique, in part because of the high labor req...
