Ex-situ collection of the genetic resources (grapevine collection). Establishment of a reference database with pictures, SSR-marker data, herbarium material and descriptor data as a basis for the assessment of true-to-typeness.
In international grapevine collections about 5 to 10 % of the grapevine varieties are not true-to-type. Material transfer between grapevine collections lead to a proliferation of mistakes. Research work, breeding tasks, preservation of genetic...
Term: 2008-01-01 bis 2025-12-31Old endemic grapevine varieties: search, safeguarding, description, characterisation, identification, preservation in ecologically maintained vineyards, analyses of parentage
Particularly in Germany various influences and incidents lead to a reduction of genetic diversity of grapevine varieties. It is aimed to rediscover and to preserve old robust grapevine varieties for present and future use. In 2000, a 100-year old...
Term: 2008-01-01 bis 2025-12-31Vitis International Variety Catalogue
The Vitis International Variety Catalogue comprises about 22.000 Vitis-species, grapevine varieties and important breeding lines. Internet users have access to variety-specific IPGRI-passport data, morphological descriptor data, results of...

Compilation of viticultural institutions (worldwide) with grapevine collections. Furthermore, addresses, geographic sites, climatic data, composition of the grapevine collections, conservation methods, etc. are specified. More than 16000 cvs. are...
Term: 2008-01-01 bis 2025-12-31Breeding of vines resistant to fungus diseases (Plasmopara, Oidium, Botrytis) with high quality
The development of new grapevine varieties with a complete or most extensive resistance to the viticulturally important fungus diseases (Plasmopara, oidium, botrytis) reduces considerably the plant protection measures and contributes thus to an...
