Passport Data Completeness Index (PDCI)
Genesys uses the PDCI as an indicator of the completeness of published passport data. The PDCI uses the presence or absence of data points in the documentation of a genebank accession, taking into account the presence or value of other data points (van Hintum et al. 2011). For example, a wild accession should have a well-defined collection site but no variety name. The PDCI ranges from 0 to 10, where 0 is the minimum score assigned to rather incomplete passport records and 10 is the maximum score assigned to very complete passport records. Any type of accession, wild, landrace, breeding material or modern variety, can attain the PDCI’s maximal score.
Average PDCI score for 30,472 accessions is 3.11, with minimum score of 1.65 and maximum score of 5.80.
