Documentation of the ECPGR Tomato Database
The passport data in the ECPGR Tomato database are presented in a format based on the EURISCO descriptor list. However, compared to EURISCO, the following modifications have been made:
The characterization data follow the Minimum descriptors for Tomato by the ECPGR Working Group on Solanaceae, April 2008.
- The descriptor "National Inventory code" has been removed.
- One non-EURISCO descriptor has been added (34).
Passport descriptor list
- 1. Institute code (INSTCODE)
- FAO Institute Code of the institute where the accession is maintained.
- 2. Accession number (ACCENUMB)
- This number serves as a unique identifier for accessions within a genebank collection, and is assigned when a sample is entered into the genebank collection.
- 3. Collecting number (COLLNUMB)
- Original number assigned by the collector(s) of the sample, normally composed of the name or initials of the collector(s) followed by a number. This number is essential for identifying duplicates held in different collections.
- 4. Collecting institute code (COLLCODE)
- Code of the Institute collecting the sample. If the holding institute has collected the material, the collecting institute code (COLLCODE) should be the same as the holding institute code (INSTCODE). For bred material the field COLLCODE should be left empty and the field BREDCODE (19) be used instead.
- 5. Genus (GENUS)

- Subtaxa can be used to store any additional taxonomic identifier, in latin. Following abbreviations are allowed: ‘subsp.’ (for subspecies); ‘convar.’ (for convariety); ‘var.’ (for variety); ‘f.’ (for form). Not to be confused with the descriptor SUBCROP (34) where data about the sub crop type can be be supplied in English.
