The purpose of this project is to 1) document Vitis genetic diversity present in the Geneva repository 2) ascertain the clonal identity of replicate vines that represent each accession. This project runs in parallel with the fingerprinting effort of the Vitis germplasm repository in Davis, California. Markers, standards and DNA extraction were coordinated between the sites, while electrophoresis and analysis was done on different genetic analyzers and slightly different programs. The genetic data collected in Geneva during 2007/2008 timeframe is the result of the first phase and includes genetic diversity data for eight SSR markers for the second vine of each accession (if present). In 2008/2009 the process is repeated for the first vine of each accession. Gaps in the current data due to lack of replicate vines will then be filled in and any discrepancies between readings of the two clonally propagated vines per accession will be dealt with. A potential future third phase may add additional diversity data for a subset of accessions.
