Vitis International Variety Catalog
Vitis International Variety Catalog (VIVC for short) is a database of the grape varieties known in official grape collections within the Vitis family . VIVC is administered by the Geilweilerhof Institute for Vine Breeding in Siebeldingen (Rhineland-Palatinate).
Work on the database began in 1983 and VIVC has been accessible online since 1996. The establishment of the database was supported by the predecessor organization of the International Organization for Vine and Wine , the International Office for Vine and Wine , and the International Board for Plant Genetic Resources , a predecessor organization of Bioversity International . The primary goal of the VIVC database is to provide data that can be used by vine growers, ampelographers (grape variety experts) and other interested parties.
scope
So far, public domain information from 130 international institutions in 45 countries has been evaluated and updated. Currently (February 2012) the database surely has more than 41,400 records for over 18,000 varieties. A retrieval according to the "Utilization" criterion with all five characteristics resulted in the following picture:
| Expression | Number of varieties | Number of records |
|---|---|---|
| Unspecified | 8,484 | 10.155 |
| Wine | 9,686 | 31,243 |
| Table grapes | 4,725 | 17,585 |
| "Raisin" | 113 | 805 |
| "Rootstock" | 1.405 | 3.831 |
You must not add these values, however, because each data record can contain none, one or more of these values. The differences between the number of varieties and the number of data records are explained by the fact that there is one data record for each “holding institution”. For Germany there are seven “Holding Institutions” registered in the database, a total of 139.
VIVC provides information on the superordinate family, the origin, the maintenance breeders or the vine collections as well as the known synonyms of each grape variety. In the case of a new breed , the breeder and the crossing partner are specified. Through the use of DNA analysis, more and more historically created natural crossings are determined. These crossing partners are also entered. In rarer cases, images and genetic information are also available. For some varieties there is information on cultivation in different countries in different years (Table of area).

- ↑ The values of "Not specified" (no entry in "Utilization") and "Wine" (most of the data sets) can be safely added.
- ↑ Example: 98 of the first 100 data sets with "Raisin" have at least one other value and only 2 are exclusively "Raisin".
