This bulletin reviews the current status of research knowledge on bean common mosaic potyvirus (BCMV) and reports the results of a survey of the occurrence of BCMV in the main bean-growing areas of Africa. The strain of each BCMV isolate collected has been identified by its reactions on a standard set of differential bean cultivars and distribution maps of strain occurrence have been prepared for each country surveyed. BCMV isolates were collected from Phaseolus vulgaris bean crops and from wild species of legumes and other non-Phaseolus legume crops
