List of 73 species analyzed and their corresponding prioritization category, genepool, ploidy level, native areas and count of data retrieved for this study.
Fig 2.
Distribution of the wild relatives of potato and hotspots for collecting.
A) Distribution of germplasm and herbarium records included in the analysis. Red dots represent germplasm accessions (G) and dark gray dots herbarium/presence records (H). B) Species richness based upon environmental niche models, and C) Potential hotspots for further collecting of high priority species (HPS).
Fig 3.
Potato wild relatives’ priorities for further collecting by genepool.
Categories are: high priority species (HPS), medium priority species (LPS), low priority species (LPS), and ‘no further collecting required’ (NFCR).
Fig 4.
A) Sampling Representativeness Score (SRS), B) Geographic Representativeness Score (GRS), and C) Ecosystem Representativeness Score (ERS) gap analysis metrics for potato wild relatives. Red dots represent results per species. Dashed lines represent complete representativeness in ex situ conservation systems. A linear regression (continuous lines) depicts the mean trend for the genepool.
