Melon veinbanding mosaic, a prevalent disease in the Bushehr Province of Iran, is characterized by formation of green veinbanding in varieties of Cucumis melo L. The disease is caused by an isometric virus of about 30 nm diameter. The virus was purified by acid and neutral pH clarification, polyethylene glycol precipitation and differential and density‐gradient centrifugation. The virus formed three zones in the density‐gradient columns. It reacted with a squash mosaic virus (SqMV) antiserumobtained from the United States in agar‐gel diffusion. Likewise, a U.S. isolate of SqMV reacted with the antiserum prepared against the Iranian isolate. The virus was seed transmissible in snakemelon. This is the first report on the field occurrence ofSqMV in Iran. The Iranian isolate appears to belong to the serotype 1 of SqMV.
