The
list of multi-crop passport descriptors (MCPD) is developed jointly by IPGRI
and FAO to
provide international standards to facilitate germplasm passport information
exchange. These
descriptors aim to be compatible with IPGRI crop descriptor lists and with
the descriptors used
for the FAO World Information and Early Warning System (WIEWS) on plant
genetic resources
(PGR).
For each multi-crop passport descriptor, a brief explanation of content,
coding scheme
and suggested fieldname (in parentheses) is provided to assist in the computerized
exchange of
this type of data. It is recognized that networks or groups of users may
want to further expand
this MCPD List to meet their specific needs. As long as these additions
allow for an easy
conversion to the format proposed in the multi-crop passport descriptors,
basic passport data
can be exchanged worldwide in a consistent manner.
General comments:
• If a field allows multiple values, these values should be separated
by a semicolon (;) without
space(s), (i.e. Accession name:Rheinische Vorgebirgstrauben;Emma;Avlon).
• A field for which no value is available should be left empty (i.e.
Elevation). If data are
exchanged in ASCII format for a field with a missing numeric value, it should
be left empty.
If data are exchanged in a database format, missing numeric values should
be represented by
generic NULL values.
• Dates are recorded as YYYYMMDD. If the month and/or day are missing
this should be
indicated with hyphens. Leading zeros are required (i.e. 197506--, or 1975----).
• Latitude and longitude are recorded in an alphanumeric format. If
the minutes or seconds are
missing, this should be indicated with hyphens. Leading zeros are required.
• Country names: three-letter ISO codes are used for countries. The
ISO 3166-1: Code List can
be found at: http://www.un.org/Depts/unsd/methods/m49alpha.htm. Country
or area
numerical codes added or changed are not available on line, but can be obtained
from IPGRI
[t.metz@cgiar.org].
• For institutes the codes from FAO should be used. These codes are
available from
http://apps3.fao.org/wiews/ for registered WIEWS users. From the Main Menu
select:
‘PGR’ and ‘Download’. 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].
• The preferred language for free text fields is English (i.e. Location
of collecting site and
Remarks).
MULTI-CROP PASSPORT DESCRIPTORS
1. Institute code (INSTCODE)
Code of the institute where the accession is maintained. The codes consist
of the 3-letter ISO
3166 country code of the country where the institute is located plus a
number. The current set of
Institute Codes is available from the FAO website (http://apps3.fao.org/wiews/).
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). Follows INSTCODE standard.
5. Genus (GENUS)
Genus name for taxon. Initial uppercase letter required.
6. Species (SPECIES)
Specific epithet portion of the scientific name in lowercase letters.
Following abbreviation is
allowed: ‘sp.’
7. Species authority (SPAUTHOR)
Provide the authority for the species name.
8. Subtaxa (SUBTAXA)
Subtaxa can be used to store any additional taxonomic identifier. Following
abbreviations are
allowed: ‘subsp.’ (for subspecies); ‘convar.’
(for convariety); ‘var.’ (for variety); ‘f.’ (for
form).
9. Subtaxa authority (SUBTAUTHOR)
Provide the subtaxa authority at the most detailed taxonomic level.
10. Common crop name (CROPNAME)
Name of the crop in colloquial language, preferably English (i.e. 'malting
barley’, 'cauliflower',
or 'white cabbage')
11. Accession name (ACCENAME)
Either a registered or other formal designation given to the accession.
First letter uppercase.
Multiple names separated with semicolon without space. For example: Rheinische
Vorgebirgstrauben;Emma;Avlon
12. Acquisition date [YYYYMMDD] (ACQDATE)
Date on which the accession entered the collection where YYYY is the year,
MM is the month
and DD is the day. Missing data (MM or DD) should be indicated with hyphens.
Leading zeros
are required.
13. Country of origin (ORIGCTY)
Code of the country in which the sample was originally collected. Use
the 3-letter ISO 3166-1
extended country codes.
14. Location of collecting site (COLLSITE)
Location information below the country level that describes where the
accession was collected.
This might include the distance in kilometres and direction from the nearest
town, village or map
grid reference point, (e.g. 7 km south of Curitiba in the state of Parana).
15. Latitude of collecting site1 (LATITUDE)
Degree (2 digits) minutes (2 digits), and seconds (2 digits) followed
by N (North) or S (South)
(e.g. 103020S). Every missing digit (minutes or seconds) should be indicated
with a hyphen.
Leading zeros are required (e.g. 10----S; 011530N; 4531--S).
16. Longitude of collecting site1 (LONGITUDE)
Degree (3 digits), minutes (2 digits), and seconds (2 digits) followed
by E (East) or W (West) (e.g.
0762510W). Every missing digit (minutes or seconds) should be indicated
with a hyphen.
Leading zeros are required (e.g. 076----W).
17. Elevation of collecting site [m asl] (ELEVATION)
Elevation of collecting site expressed in metres above sea level. Negative
values are allowed.
18. Collecting date of sample [YYYYMMDD] (COLLDATE)
Collecting date of the sample where YYYY is the year, MM is the month
and DD is the day.
Missing data (MM or DD) should be indicated with hyphens. Leading zeros
are required.
1 To convert from longitude and latitude in degrees (º), minutes
('), seconds (''), and a hemisphere (North or
South and East or West) to decimal degrees, the following formula should
be used:
dº m' s''=h *(d+m/ 60+s/3600)
where h=1 for the Northern and Eastern hemispheres and –1 for the
Southern and Western hemispheres i.e.
30º30'0'' S= –30.5 and 30º15'55'' N=30.265.
19. Breeding institute code (BREDCODE)
Institute code of the institute that has bred the material. If the holding
institute has bred the
material, the breeding institute code (BREDCODE) should be the same as
the holding institute
code (INSTCODE). Follows INSTCODE standard.
