The Association of Potato Inter-genebank Collaborators (APIC) is comprised of the major world potato genebanks. These are located at:

International Potato Center (CIP, Lima, Perú)

United States Potato Introduction Project (NRSP-6, Sturgeon Bay, Wisconsin,USA)

Dutch German Potato Collection (CGN, Wageningen, The Netherlands, ex BGRC, Braunschweig, Germany)

Institute of Plant Genetics and Crop Plant Research (GLKS, Gross Luessewitz, Germany)

Commonwealth Potato Collection (CPC, Dundee, Scotland)

N.I. Vavilov Institute (VIR, St. Petersburg, Russia)

Instituto Nacional de Tecnología Agropecuaria (INTA, Balcarce, Argentina)


One of the first priorities set by APIC was the development of the Inter-genebank Potato Database (IPD), a global database of potato germplasm available in the member genebanks. The first component of this effort is the database on wild potato species containing both passport and evaluation data. The database is organized using the collector number as the key field. Each unique accession is listed only once. The passport data of each accession shows the collector number and the identification number of each genebank maintaining it, followed by all available information on the collecting site. The evaluation data are comprised of the reaction of accessions to stresses (diseases and pests) as well as to quality traits. Letter codes were adopted instead of number as most users are familiar with categories such as Very Resistant, Resistant , InterMediate, Susceptible, Very Susceptible. In the cases where more data were available, a number (1 to 9) besides the reaction code indicates the percentage (1=10% or less and 9=90% or more) of the population with that reaction. The strain or race of a pathogen is indicated in lower case letters following the reaction code, for example Sc means Susceptible to strain c. A symbol following the reaction code like an asterisk '*' means consistent reaction or a question mark '?' indicates conflicting results among evaluators. Another convention adopted was that when very few good sources for resistance are only found in a minor portion of the population, i.e. the valuable trait is rare, then the reaction was coded for example as R1 instead of S9. The results of re-evaluations of the same accession to the same pathogen are shown separated by slashes.


Since most evaluation data on wild potatoes are the results of screening populations and the data included in the database were obtained from different sources, separate records are maintained when an accession was evaluated in more than one genebank. In general, the users must validate these data. They will need to request seeds of those accessions where others have found valuable traits and screen the material under their own conditions to select the best individual plants that meet their needs.
