ternational Plant Genetic Resources Institut Descriptors for Coffee Descriptors for Coffee Definitions and Use of the Descriptors DEFINITIONS AND USE OF THE DESCRIPTORS
IPGRI now uses the following definitions in genetic resources documentation:
Passport descriptors: These provide the basic information used for the general managementof the accession (including the registration at the genebank and other identificationinformation) and describe parameters that should be observed when the accession isoriginally collected.
Management descriptors: These provide the basis for the management of accessions inthe genebank and assist with their multiplication and regeneration.
Environment and site descriptors: These describe the environmental and site-specificparameters that are important when characterization and evaluation trials are held. Theycan be important for the interpretation of the results of those trials. Site descriptors forgermplasm collecting are also included here.
Characterization descriptors: These enable an easy and quick discrimination betweenphenotypes. They are generally highly heritable, can be easily seen by the eye and areequally expressed in all environments. In addition, these may include a limited numberof additional traits thought desirable by a consensus of users of the particular crop.
Evaluation descriptors: Many of the descriptors in this category are susceptible toenvironmental differences but are generally useful in crop improvement and others mayinvolve complex biochemical or molecular characterization. They include yield, agronomicperformance, stress susceptibilities and biochemical and cytological traits.
Characterization will normally be the responsibility of genebank curators, while evaluation
will typically be carried out elsewhere (possibly by a multidisciplinary team of scientists). The evaluation data should be fed back to the genebank which will maintain a data file.
Minimum highly discriminating descriptors are marked with a star («).
The following internationally accepted norms for the scoring, coding and recording of
(a) the Système International d’Unités (SI system) is used. The units to be applied are
given in square brackets following the descriptor name;
(b) standard colour charts, e.g. Royal Horticultural Society Colour Chart, Methuen
Handbook of Colour, or Munsell Color Chart for Plant Tissues, are stronglyrecommended for all ungraded colour characters (the precise chart used should bespecified in the section where it is used);
Descriptors for Coffee
(c) many quantitative characters which are continuously variable are recorded on a 1-9
is the expression of a character. The authors of this list have sometimes described onlya selection of the states, e.g. 3, 5 and 7 for such descriptors. Where this has occurred,the full range of codes is available for use by extension of the codes given or byinterpolation between them, e.g. in Section 9 (Biotic stress susceptibility), 1 = very lowsusceptibility and 9 = very high susceptibility;
(d) when a descriptor is scored using a 1-9 scale, such as in (c), ‘0’ would be scored when
(i) the character is not expressed; (ii) when a descriptor is inapplicable. In the followingexample, ‘0’ will be recorded if an accession does not have a central leaf lobe:
Shape of central leaf lobe
(e) absence/presence of characters is scored as in the following example:
Absence/presence of terminal leaflet
(f) blanks are used for information not yet available;
(g) for accessions which are not generally uniform for a descriptor (e.g. mixed collection,
genetic segregation), the mean and standard deviation could be reported where thedescriptor is continuous. Where the descriptor is discontinuous, several codes in theorder of frequency could be recorded; or other publicized methods can be utilized,such as R.S. Rana et al. (1991), or van Hintum (1993), that clearly state a method forscoring heterogeneous accessions;
(h) dates should be expressed numerically in the format DDMMYYYY, where
YYYY - 4 digits to represent the year. Descriptors for Coffee Passport PASSPORT 1. Accession descriptors Accession number
« This number serves as a unique identifier for accessions and is assigned when an accession
is entered into the collection. Once assigned this number should never be reassigned toanother accession in the collection. Even if an accession is lost, its assigned number is stillnot available for re-use. Letters should be used before the number to identify the genebankor national system (e.g. IDG indicates an accession that comes from the genebank at Bari,Italy; CGN indicates an accession from the genebank at Wageningen, The Netherlands; PIindicates an accession within the USA system).
