Yam virus diseases were surveyed for 3 years in Burkino Faso. Mosaic and green vein banding symptoms were observed on two
species (#Dioscorea cayenensis rotundata$ and #Dioscorea alata$) in the south-west and southern aeras, and on the Pilimpikou
yam cultivar in the central area. Using electron microscopy, ELISA and host range studies, it was found that plants were infected
with a potyvirus similar to yam mosaic virus in host range, morphology and serology. This virus was not detected in the southern
area but occurred at a low rate (13%) in the south-west and more frequently (71.5%) in the central aera. Healthy yam plants were
exposed to natural infection for 5 months in these two areas and checked for virus contamination by ELISA. Tubers from markets
were...
