Commonwealth Potato Collection

Image of Mayan Gold potatoesThe Commonwealth Potato Collection is a major genebank containing over 1300 accessions of 86 different species related to the cultivated potato S. tuberosum L.

Information on species available may be accessed via an alphabetical species list which includes country of origin, endosperm balance number (EBN) and chromosome numbers, CPC identification numbers, photograph (via links) and evaluation data on individual accessions. Evaluation data for species are available via a list of known resistances.

All accessions listed have been screened and declared free of potato spindle tuber viroid (PSTV). A significant proportion have also been tested for other viral diseases known to be seed-transmissible: Andean potato latent virus (APLV); potato black ringspot virus (PBRV) (tobacco ringspot nepovirus (TRSV-Ca)); Arracacha B nepovirus, oca strain (AVB-O) potato T capillovirus (PVT) and potato yellowing virus (PYV).

Material is mainly held as seed and is freely available on request to all recognised research, breeding and educational establishments world-wide. Tuber samples may also be requested. Please contact us for availability as supplies are limited.
