Identified gaps for Hordeum genepool

(see downloads)

We found data for 27 wild species and 1 infraspecific taxon (H. vulgare subsp. spontaneum). The different taxa are classified as follows, according to their closeness to the cropped species H. vulgare subsp. vulgare using Maxted and Kell (2009) as follows:

The analysis dataset (download) contained 12,627 observations, with 10,977 (87%) being herbarium specimens and 1,650 (13%) being genebank accessions. The average number of total samples per taxon was 451 (standard deviation of 1,488), indicating data is abundant but concentrated in certain taxa. H. secalinum (meadow barley), accounting to a total of 7,797 samples (99% herbarium samples and 1% genebank accessions), H. bulbosum (bulbous barley), accounting to a total of 1,457 (77% herbarium and 23% germplasm), and H. pusillum (little barley), accounting to a total of 1409 (96% herbarium and 4% germplasm) are the taxa in which the great majority of data points are concentrated. Other taxa such as H. guatemalense (3), H. erectifolium (5), H. capense (9) were found to be less collected, less georeferenced or less characterized and they thus will require more extensive sampling to assess a ecogeographic characterization.

The gap analysis of the Hordeum genepool found that there are 10 taxa (H. brachyantherum, H. capense, H. comosum, H. cordobense, H. erectifolium, H. flexuosum, H. fuegianum, H. guatemalense, H. procerum, H. tetraploidum) that are either underrepresented or not represented in genebank holdings out of the 28 taxa under analysis and these taxa were therefore flagged as high priority species. There are 6 taxa (H. arizonicum, H. depressum, H. euclaston, H. intercedens, H. pusillum and H. secalinum) which are relatively poorly conserved ex-situ and were thus flagged as medium priority species; while 10 taxa are relatively well conserved (H. bogdanii, H. brevisubulatum, H. bulbosum, H. lechleri, H. muticum, H. parodii, H. pubiflorum, H. roshevitzii, H. stenostachys, H. vulgare subsp. spontaneum). Only two taxa were found to not require further conservation (H. chilense and H. patagonicum). Potential sampling zones were calculated for high priority species and are shown as follows:

Hordeum high priority taxa were found to be distributed in North America (western region of Canada and USA) and South America (Bolivia, Chile and Argentina). Zones in the figures above are those in which the species is likely to exist and no genebank accessions have been collected.

Brief description of data used in the analysis

Hordeum centers of diversity are found in Southwestern Asia, Central Asia, western North America and southern South America. Is it widely distributed in temperate areas in both hemispheres. The table below shows the number of records (herbarium, germplasm, total) used per species for the Hordeum genepool gap analysis.

Species’ taxonomy was reviewed using Maxted et al. (2005) as a first stage, the GRIN taxonomical review in second place, and the Royal Botanic Gardens, Kew taxonomy database. After cross-checking and correcting both synonyms and orthography of the species’ names, a thorough georeferencing process is carried out to obtain a spatially explicit database containing as many records as possible for each species. After this, records outside continental boundaries were deleted and a final dataset was produced for analyses (download dataset).
