Two potyviruses infecting cucurbits, first isolated in southern France and northern Italy and described as muskmelon yellow stunt virus and zucchini yellow mosaic virus, respectively, have been compared serologically and found indistinguishable. In view of other similarities in host range, symptoms, aphid transmission, and particle morphology, the two are considered to be a single virus for which we propose retaining the name zucchini yellow mosaic virus.
