摘要

Virus disease is a major constraint to squash (Cucurbita moschata) production in most areas where the crop is grown. To assess what were the predominant and emerging virus diseases of squash in Taiwan, a field survey was conducted in 2016 and 2017. More than 600 samples from different squash plants with virus-like symptoms were collected from 15 counties of Taiwan and the virus (es) present were diagnosed by ELISA and PCR. Across all the samples, the predominant viruses were from the genera Begomovirus and Potyvirus. Further testing showed that Squash leaf curl Philippines virus (SLCuPV; Begomovirus) and Papaya ringspot v/ras-watermelon type (PRSV-W; Potyvirus) were the main viruses present being detected in nearly 50% and more than 43% of samples,respectively. The distribution of the two viruses was different in the different regions of Taiwan, with SLCuPV predominant in the south and east of Taiwan, while PRSV-W was more prevalent in the northern and central counties of Taiwan. Zucchini yellow mosaic virus (ZYMV; Potyvirus) was identified as the second most important virus in north and east of Taiwan while it was the third most important in the central and southern parts of Taiwan. Watermelon mosaic virus (WMV; Potyvirus) was only identified insamples collected in northern and central Taiwan, while Cucurbit chloroticyellows virus (CCYV; Crinivirus) was mostly identified in the south and east of Taiwan. These results suggest that in order to reduce the production losses of squash caused by virus disease in Taiwan, it is essential to breed cultivars with durable resistance to both SLCuPV and PRSV-W.
