Total – entire germplasm collection (pooled sample treated as a single population); N – sample size; n – mean sample size over loci; A – number of different alleles; a – mean number of alleles per locus; AE – effective number of alleles; HE – unbiased expected heterozygosity; HO – observed heterozygosity; F – fixation index (inbreeding coefficient); MAF – minor allele frequency.
