Genetic diversity in the sorghum Global Composite Germplasm Collection (GCGC) and in the Reference Set, partitioned into biological status, races and geographic origins as indicated in passport data.

1calculated over 383 diploid genomes.Partition into geographic origins is limited to landraces and wild samples for which geographic origin relates to reality.N: number of accessions; Na: total number of alleles; MeanNa: mean number of alleles per marker, ARich: allelic richness calculated according to Petit et al. (1998) as in [41] for standard sample sizes of 100 genomes; PrivA: Private allele number per marker calculated according to [41] for standard sample sizes of 100 genomes (allelic richness and private allele number per marker were calculated for those classes which presented more than 100 genomes, by continent – Africa, Asia and Northern America – and in each sub-continent – Africa and Asia –), before the pipe are the values observed inside the continent, each continent being analyzed separately, after the pipe are the values observed when all 3 continents are analyzed together at the sub-continent level; Ho: observed heterozygosity.
