| Title | Multi-state Evaluation of Winegrape Cultivars and Clones |
| Investigator(s) | Caspari, HW; |
| Department | Horticulture and Landscape Architecture |
| Objectives | 1) Evaluate the viticulture characteristics and wine quality potential of clones of economically significant cultivars throughout the USA. 2) Characterize the viticultural and wine quality potential of emerging cultivars based on regional needs. 3) Conduct explorations within and outside of the USA for new or lesser known cultivars that may have economic potential for the US wine industry. |
| Approach | Grape cultivars and clones of potential economic value will be selected and grouped based on interest and need for various states and region. Although not every item will be tested in every site, all items will be tested over a range of sites so that genotypic influences may be distinguished from environmental influence. Vineyard establishment and management will be based on Best Management Practices. Standard viticultural measurements will be collected each year at each site. |

| 2005 | Objectives are to Evaluate the viticulture characteristics and wine quality potential of clones of economically significant cultivars throughout the USA. 2) Characterize the viticultural and wine quality potential of emerging cultivars based on regional needs. 3) Conduct explorations within and outside of the USA for new or lesser-known cultivars that may have economic potential for the US wine industry. Two meetings were held in 2005 (May 25-26 at UC Davis, CA; November 2-3 at AHS Jr. Agricultural Research & Extension Center, Winchester , VA). Aside from the business meeting (election of officers for next year, etc) the main emphasis of those meetings was to further define the Material and Methods. Three sub-committees were formed during the latter meeting to develop protocols for 1) juice analysis, 2) nutrition, and 3) meteorology. Also, researchers with existing trials receiving funding via the Viticulture Consortium (East and West) agreed to coordinate both their proposals and methodology for the upcoming funding cycle. No new plantings were added in 2005 . A prioritized list of varieties for the first planting was provided to the Chair in November 2005. Plant material is being prepared for new plantings starting in spring 2007. |

Keywords grape, wine, cultivars, clones, quality Progress Report 2006 A proposal submitted by Jim Wolpert, UC Davis on behalf of the Western states (CA, CO, ID, OR, TX, WA) for partial funding of planting material received funding from Viticulture Consortium West. The annual meeting was held November 14-15 at the Brownstone Hotel, Raleigh, NC. Aside from the business meeting (election of officers for next year, etc) the main outcome was a modification of the climatic site classification based on a 3 x 3 matrix (cool, warm, or hot growing season; mild, cold, or very cold dormant season), and the coordination of planting plans among states. A list of varieties for the first planting was provided to a nursery in December 2006. Plant material is being prepared for two new plantings in spring 2008. |
| Impact | |
| 2005 | The ultimate outcome of this project is the identification and industry adoption of well-adapted Vitis species/cultivars/clones that will allow grape growers and wineries to be more competitive in the market place, and thus improve the economic viability of the Colorado grape and wine industry. |
