N acc.: Number of sunflower accessions; N ind.: Number of individuals analyzed; A: number of alleles; a: mean number of alleles per locus; He: unbiased expected heterozigosity, Ho: observed heterozigosity. Sunflower accessions were grouped according to the categories described in the Methods section.
