Table 2 Summary of genetic diversity measures for the complete accession panel and selected subgroups based on 567 polymorphic SNPs. Both within accession averages and total diversity within groups are shown as well as diversity upon sample pooling in silico. N: sample size – number of accessions (number of individuals within brackets); Na: number of alleles; H_O: Observed Heterozygosity; H_E: Expected Heterozygosity; F: Fixation Index
