A Mosaic of Beans (Phaseolus vulgaris L.) Caused by a Strain of Common Cucumber Mosaic Virus

Abstract

A virus (BVBMV) capable of inciting mild mosaic and vein-banding symptoms on various hosts was isolated from field beans (Phaseolus vulgaris L.) growing in experimental plots. The causal agent was transmitted by mechanical means as well as via aphids. The results of transmissibility, serology, host range and physical property studies indicate that the virus is a strain, possibly a new one, of the common cucumber mosaic virus (CMV) complex.

“…Finally, mild mosaic and severe plant malformation were observed in bean. Pods can be reduced in number or only partially filled with seeds, resulting in yield losses, whose incidence ranges from 5% to 75% depending on the cultivar, age of infection, virus strain, and environmental conditions [ 197 ].…”
