This document summarizes a gap analysis conducted on the genetic diversity of potato crops. Gap analysis is a tool used to assess levels of crop genetic and geographic diversity currently held in ex situ conservation systems. It identifies taxa that are high priorities for further collection to fill gaps, as well as their geographic locations. The analysis found that two varieties within the Rugosi and Acutifolii sections of potato - P. carteri and P. acutifolius var. latifolius, respectively - were high priority for further collection. It also provides maps indicating priority areas to collect these taxa. The methodology and results of this and other crop gap analyses are publicly available online.
