Progress 08/01/10 to 07/31/13
Outputs
Target Audience: Target audiences are grape industry leaders, agricultural pest control advisers, crop consultants such as Certified Crop Advisers, growers, farmers; Cooperative Extension advisors, specialists and staff; USDA NRCS professional staff; public agencies. In addition, new findings support the work of other researchers viticultural issues. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided? The project provided opportunities for graduate student in-lab and in-field training and postdoctoral development. How have the results been disseminated to communities of interest? Two primary dissemination venues were used: 1) The Wine and Wine Grape Research Conference sponsored annually by the PI and 2) UC Integrated Viticulture website http://iv.ucdavis.edu/. Scientists funded through this program gave presentation at this conference which were recorded and posted online on the website. In addition, publications coming out of this research were also posted on the website. In addition, individual researchers presented their results at scientific meetings--particularly the American Society of Enology and Viticulture, the American Horticulture Society and the Phytopathological Society Annual Meetings--and at meetings of the wine and grape industries. What do you plan to do during the next reporting period to accomplish the goals?

Progress 08/01/10 to 07/31/11
Outputs
OUTPUTS: The Viticulture Consortium West (VCW) project at the University of California was initiated in 1996 and was continued by Agreement CA-SW-ADM-7884-SG. Our objective continues to be to assist in developing and maintaining competitive Viticulture industries in the Western States, Texas and Oklahoma through a peer reviewed sub-grant research program. A Guidance Committee (GC) of industry, research and extension personnel assists in identification of priority research areas and advising the Director in operation of the program. Annual requests for research proposals were sent to the Western Experiment Station Directors and Deans and other universities. Peer reviews of proposals received were solicited and used by scientific review panels in the selection of proposals to be funded. For this grant, the VCW received 77 proposals and funded 20 sub-grants to investigators from Land Grant and State Universities, Cooperative Extension and the USDA/ARS from 4 states. Industry, including table, wine and raisin grapes has continued their commitment to provide matching support of the CSREES grant. PARTICIPANTS: By including industry representatives in the planning and decision processes of the VCW, our California industry has maintained its commitment to provide at least one-to-one matching funds of support dollars to those provided by USDA-NIFA. Researchers who received VCW funds from states other than California also received matching funds from their state rganizations or the American Vineyard Foundation. The viticulture industry has reaffirmed its commitment to provide matching funds for the 2010 round of research covered by this proposal. The members of the Guiding Committee can be seen on the VCW website at: http://ucanr.org/sites/vcw/ TARGET AUDIENCES: Target audiences include the research community, grape growers, wine makers, and others interested in research progress in the grape community. To expand outreach to our target audiences, in February 2010, VCW invited all researchers who had received recent funding from one of the Unified Grant Management for Viticulture and Enology agencies to present their research at an all day symposium co-sponsored by UC Davis Extension. Researchers presented their research in the areas of grapevine breeding and evaluation, cultural practices, and disease and insect pest control. Approximately 100 people including growers, nursery personnel, farm advisors, and researchers attended these meetings. Presentations were videotaped and can be viewed online at http://ucanr.org/sites/intvit/ PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Sub-projects funded include research with both near and long term objectives ranging from practical application in the field to basic research. Funded sub-projects specifically addressed: Disease and pest control: - Temporal and spatial studies of leafroll disease and mealybug vectors; - A microbiome-based approach to managing grape powdery mildew; - Lamp PCR for detectionbased management programs; - Etiology and detection of the cause of Syrah Decline; - A general study of Grapevine Leafroll Disease; - Characterization of new grapevine leafroll-associated viruses. Cultural Practices: - Yield components of cane-pruned raisin grapes; - Modeling grapevine cold hardiness as an on-line decision tool; - Cultural practices to modify berry cracking; - Aquaporin-regulated response of grapevine roots to salinity; - Impact of cover crop management on mycorrhizal community structure; - Crop yield and economics of alternative weed management strategies; - Impacts of early season fruit zone leaf removal; - Identifying fruit damage in raisin production systems. Outreach and Extension: - Developing social networking tools for viticulture. Breeding and Germplasm: - Rootstock tolerance to salinity; - Improved raisin grapes for mechanical harvest; - Development of seedless grapes for the fresh market; - NE-1020 coordinated wine grape cultivar evaluation in Western U.S.; - Marker-assisted selection to introgress powdery mildew resistance in wine grapes. Information developed has been distributed through professional, industry and trade journals, annual reports, and presentations at scientific and grower/industry meetings.
