P-72 The software for a “Universal Grapevine Database” C. D’Onofrio Department of Fruit Science and Plant Protection, section of Fruit Science, University of Pisa, Pisa, Italy Corresponding author: c.donofrio@agr.unipi.it Software for a “universal grapevine database” has been developed to support the characterization of grapevine biodiversity. In this database, registered users may submit and manage their own data at any time, and the introduced data may have three different levels of visualisation: private level (the data are visible only to the submitter), middle level (the data are visible to all other submitters), public level (the data are visible to all public users). Only the data approved by a specific scientific committee may be elevated to public level. When a submitter introduces microsatellite data into the database, the application allows a specific standardization procedure based on some specific selected accessions called ‘system accessions’. The main classes of data represented in the database are the ‘grapevine variety’, the ‘ampelographic-ampelometric and phenological-productive descriptors’ (as reported in the second edition of the OIV descriptor list for grape varieties and Vitis species), the ‘microsatellite profile’, and the polyphenol and aroma profiles. Several search options have been implemented: a search by variety and other general parameters, a search by ampelographic and ampelometric parameters, and a search by microsatellite profile. In the microsatellite profile it is also possible to search by range and by a particular standardization procedure. The application has been implemented using the most recent database software and languages, so it is flexible and dynamic especially as with regard to the addition of other classes of data, like new type of descriptors and molecular markers. The application is on the web at http://www.vitisdb.it and at present it is adopted for the ‘Italian Vitis Database’, managed by the “Vitis Database Working Group”. 153 
P-73    Molecular characterization of the grapevine germplasm collection held at the Fondazione Edmund Mach F.M. Moreira*, S. Lorenzi, M. Sordo, L. Zulini, M. Stefanini, M.S. Grando IASMA Research Centre, Fondazione Edmund Mach, San Michele all’Adige, Trento, Italy *Corresponding author: flavia.moreira@iasma.it The grapevine germplasm collection maintained by FEM-IASMA was set up in the 1980s from a small core of pre-existing varieties, which was supplemented with material from various international sources, as well as minor and wild grapevine varieties from Italy. It currently includes about 2,000 accessions of Vitis vinifera sativa and several hundred individuals of V. vinifera sylvestris, as well as other species of the genus Vitis and hybrids. All accessions are planted in the same locality in five replicates on Kober 5BB rootstock and trained on the Guyot system. Growing scientific interest in the genetic diversity of grapevine, together with the need to improve the organization of materials and streamline management costs has given rise to a project aimed at characterizing all the conserved germplasm. In an initial molecular analysis, one plant of each accession was typed at ten microsatellite loci (SSR). Comparison of the profiles obtained allowed the genotypes present to be identified and hence the number of accessions to undergo further investigation to be reduced. The extension of genotyping to 12 other SSR loci confirmed the consistency of the collection’s gene pool. Using assignment experiments, comparisons with international databases and ampelographic verification, grape varieties with the same SSR profile are attributed to cases of synonymy or denomination errors. The most interesting phenotypic variations amongst plants with an identical SSR genotype will be selected for conservation. The set of accessions with a non-redundant genotype is the collection’s main source of genetic diversity. Regarding this material, intense genotyping of hundreds of SNP loci is underway in order to identify appropriate core collections for future association studies. Some of the characteristics emerging from this study and other potential evaluations of the collection’s contents will be presented. 154
