Potato yellow vein virus

PYVV

Potato yellow vein virus is a Crinivirus whose only host is the potato.[1]

Symptoms[edit]

Newly developed symptoms are bright yellow veins and, in some cultivars, interveinal yellowing. Later the leaves become yellow and the veins may turn green. Some rugosity and necrotic spotting may also develop. Tubers may be deformed, with large protruding eyes.[1]

Control[edit]

As with all potato viruses, control depends on the production of high-quality seed potatoes from virus-free nuclear stock.[1]
