The following parameters are shown for the genetic groups detected by STRUCTURE analyses of Iberian and Moroccan accessions and of all worldwide accessions: number of populations (N), percentage of polymorphic loci (PL), gene diversity (H_S), allelic richness (R_S) and private allelic richness (R_P) per locus. H_S, R_S and R_P are mean values ± SE.
¹: Genetic group 3 is divided into Moroccan and Iberian accessions in the top analysis.
