  abstract = {{Y}am mosaic virus ({YMV}), a member of the {P}otyvirus group, causes a severe disease of yam, #{D}ioscorea$ spp., mainly in {A}frica and the {C}arribean. {T}here have been no data available hitherto on the quantitative effects of the disease on crop yield, due to difficulties in detecting the presence of the virus in plant. {B}y using {ELISA} tests to identify healthy yam material prior to and after planting, reliable estimates of crop losses due to {YMV} were obtained through serial field trials over a three years period. {F}resh tuber weights obtained from diseased #{D}ioscorea alata$, cv. {F}lorido averaged 15% lower than those obtained from healthy plants grown under similar conditions. {T}here was no difference however in the number of tubers formed. {D}isease contamination by aphid vection during crop growth was found to be relatively slight compared to disease levels in the initial seed tubers. {T}his suggests that selection of virus-free tubers could rapidly eradicate yam mosaic disease.
