Vitis International Variety Catalogue

Vitis International Variety Catalogue ( short VIVC ) is a database to the known in official Rebsammlungen varieties within the family of Vitis. VIVC is managed by the Institute for Grapevine Breeding Geilweilerhof Siebeldingen.

Work on the database began in 1983 and since 1996 VIVC is accessible online. The creation of the database was supported by the predecessor organization of the International Organization of Vine and Wine, the International Office of Vine and Wine, and the International Board for Plant Genetic Resources, a predecessor organization of Bioversity International. The primary goal of VIVC database is to provide data that can serve Rebzüchtern, ampelographers and other interested parties.

Scope

So far were evaluated and entered information from 130 international institutions in 45 countries public domain (public domain ). Currently (February 2012 ), the database has more than 41,400 records safely to 18,000 varieties. A call by the criterion " Utilization" with all five characteristics was as follows:

Not specified: 8,484 varieties with 10,155 records, Wine: 9686 varieties with 31 243 data sets, table grapes: 4,725 varieties with 17,585 records, " Raisin ": 113 varieties with 805 records and " Rootstock ": 1,405 varieties with 3,831 records. These values ​​may not add to but because each record can contain none, one or more of these values ​​. The differences between the number of varieties and number of records explained by the fact that there is one record per " holding institution." For Germany are seven " Holding Institutions" registered in the database, a total of 139

VIVC provides information to the parent family of origin, preservation breeder or Rebsammlungen and the known synonyms of each grape variety is available. In case of a new breed of breeders and breeding partners are given. Through the use of DNA analysis historically developed natural intersections are determined propagated. These crossing partners be entered. In rarer cases, illustrations and gene information are available. For some varieties, there is information for cultivation in different countries in different years (Table of area).
