The software for a “Universal Grapevine Database”

A software for an “universal grapevine database” have been developed to support the activity of characterization of grapevine biodiversity. In this database the registered users have the possibility of to submit and to manage his own data at any time, and the introduced data have three different level of visualisation: private level (the data are visible only to his submitter), middle level (the data are visible to all other submitter), public level (the data are visible to all public users). Only the data approved by a specific scientific committee could be elevated to public level. When a submitter introduce the microsatellite data in the database the application allow 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’, the polyphenols and aroma profiles. Several search options have been implemented: a search by variety and other general parameter, a search by ampelographic and ampelometric parameters, a search by microsatellite profile. Several search options have been implemented: a search by variety and other general parameter, a search by ampelographic and ampelometric parameters, a search by microsatellite profile. About microsatellite profile it is also possible a search by range and by a particular standardization procedure. The application have been implemented using the most recent database software and languages, so it is flexible and dynamics especially as concern 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”
