Project on Minor Fruit Tree Species Conservation - RESGEN 29

DESCRIPTOR LIST FOR CAROB TREE (Ceratonia siliqua L.)

(For ex situ conservation)

PASSPORT - Accession and collection data

1 - European minor fruit tree species database (EMFTSD) number: unique numerical identifier for an accession;

2 - Species: to be repeated for each accession (botanical name);

3 - Accession designation: name of the accession (cultivar, breeder’s designation, donor’s designation);

4 - Accession synonym: a synonym to the accession designation. For each species with synonyms, a common accession designation should be identified for each partner and then synonyms should be quoted here;

5 - Donor name: name of institution or individual responsible for donating the germplasm;

6 - Acquisition date: the date on which the accession entered the collection in the form of DDMMYYYY;

7 - Collecting institute number: the partner number from technical annex of project. The same number reported in the institution database file;

8 - Country keeping the accession: two letters acronym of country in which the partner and the collection is located (see attached list);

9 - Collection site: if one institution holds accessions in more than one environmentally different field, each field should have an identifier site number;

10 - Country of origin: when certainly known two letter abbreviation (according to attached list) for country of origin of the accession; if not sure, type ‘uncertain’;
