| Abstract: | A virus disease causing severe mosaic in melon (the melon isolate) was identified as a strain of zucchini yellow mosaic virus (ZYMV). Identification was based on host range, aphid transmissibility, electron microscopy, and serological tests. The virus was recovered from all cultivated cucurbits in Jordan and from naturally infected Moluccella laevis. It was seed-transmitted in Ranunculus sardous. Host-range comparison showed that the melon isolate and a French isolate belong to a different biotype group from a Connecticut isolate (ZYMV-CT); this was confirmed by indirect ELISA. During 1987–1988. ZYMV appeared to be the predominant virus affecting cucurbits. |
