Cucurbit viruses of squash in Jordan.

Abstract

The virus causing the greatest economic problems to squashes in Jordan is zucchini yellow mosaic potyvirus (ZYMV). It was found as a single or mixed infection in 82.6% of 910 samples. The second virus, watermelon mosaic 2 potyvirus (WM2V) was detected in 13.5% of tested samples as a single infection and in 48.2% as a double infection with ZYMV. Cucumber mosaic cucumovirus (CMV) and squash mosaic comovirus (SqMV) were not present in significant quantities. Papaya ringspot potyvirus was not detected in 910 infected samples tested during the survey. ELISA showed that some weeds may act as a primary source of inoculum to cucurbit viruses in Jordan.
