Cucurbit--Watermelon Mosaic Potyvirus (WMV, formerly WMV-2)

Summer squash leaves show mosaic symptoms caused by Watermelon Mosaic Potyvirus (formerly WMV-2).

Mosaic and rugosity of foliage and color breaking on fruit of straightneck yellow squash caused by Watermelon Mosaic Potyvirus (formerly WMV-2).



Note mosaic on foliage but absence of color breaking on fruit infected with Watermelon Mosaic Potyvirus (formerly WMV-2). Presence of a yellow precocious gene in the variety 'Multipik' and other varieties prevents color breaking from occurring.
