Research Project: Impact of Grapevine Viruses on Idaho Grape Quality

Location: Horticultural Crops Research

Project Number: 2072-21000-047-09-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Dec 2, 2013
End Date: Jul 31, 2016

The project goal is to expand on our preliminary research efforts regarding Idaho grapevine viruses and relate this to its influence on fruit quality.

A new virus of grapevine, first reported in October, has been detected in Oregon, Washington, and California. Idaho vineyards will be surveyed to see if this newly emerging virus (Grapevine red leaf blotch virus, GRLBV), along with other newly described viruses (Grapevine virus E and F) are present in Idaho vineyards. Fruit quality component analyses will accompany the virus detection, since not all grapevine viruses are known to reduce quality (color, sweetness, acidity, etc.)
