Sets of microsatellites extracted from both a genomic library (gSSRs) and from expressed sequence tag sequence (eSSRs), and single nucleotide polymorphisms (SNPs) were applied to assess the levels of genetic diversity in a sample of 70 barley accessions, originating from 28 countries in Asia, Africa, the Middle East and Europe. The eSSR assays detected a mean of 9.5 alleles per locus, and the gSSRs only 5.7 alleles per locus, but the polymorphism information content values for the two assay types were indistinguishable. Strong and statistically significant correlations were observed between the eSSR and gSSR (r?=?0.86, P?
