Remarks to prime names and institute codes
(WIEWS) - Institute codes are part of the FAO / Bioversity Multi Crop Passport Descriptor list, which have been internationally agreed to harmonize plant genetic resources databases worldwide and simplify data exchange. If new Institute Codes are required, they can be generated online by national WIEWS administrators, or by the FAO WIEWS administrator [Stefano.Diulgheroff@fao.org]
Principles employed for cultivar name registration in the database.
1. If several names (synonyms) of one grapevine cultivar are known, it is necessary to define a prime name:
2. The prime name of a grapevine cultivar is always accompanied by the berry colour, using:
3. If a prime name is composed out of name of the cultivar plus descriptor, e. g. ripening time, berry colour, they are arranged in the following order:
4. The following rules are applied if the prime name of a cultivar consists of the breeders name or location and breeding number:
5. The prime name is indicated without genera if the species is part of the prime name.
6. All language-specific symbols (accent, cedilla, tilde, dieresis) of prime names are omitted.
7. Prime names of cultivars given in Cyrillic letters are transliterated by using rules of Chemical Abstracts.
Example: Magaracha rannii N
8. Tetraploid cultivars are additionally marked (4N)
Example: Chasselas blanc B (4N)
9. If a cultivar is the descendant of different species it is registered as Interspecific crossing in the field Vitis species.
Seibel 1 N is a cross of Jaeger 70 x Cinsaut and therefore registered as Interspecific crossing in the field Vitis species
