A virus, hitherto unreported in Cote d'Ivoire, was detected in groundn
ut plant (Arachis hypogaea) from the northern parts of the country. In
fected plants showed mottling, interveinal depression, and very promin
ent light and dark green patches on leaves. The causal agent was chara
cterized as a strain of peanut mottle virus, a member of the polyvirus
group, on the basis of its host range, mode of transmission, physical
properties, particle morphology and on the basis of its serological p
roperties studied in comparison with these of other groundnut viruses.
