First Report of Zucchini Yellow Mosaic Virus on Cucurbits in the Central Region of Saudi Arabia

A greenhouse grown cucumber virus isolate from the Deriyah area induced symptoms on squash Cucurbita pepo L. resembling those incited by zucchini yellow mosaic virus ( ZYMV ) . This isolate has a host range similar to that of an ZYMV-original isolate, except that it did not infect Gomphrena globosa L. . The complete identification of ZYMV was based on its physical properties, aphid transmission , morphology by the electron microscope, and serological properties . This study confirms the presence of ZYMV infection of cucumber and bottleground plants for the first time in the central region of Saudi Arabi
