Table 4. Genetic diversity measures for each of the genetic groups defined with STRUCTURE at K = 2, K = 3 and K = 5.
Number of genotypes (n), number of reference cultivars (nR), number of alleles (NA), number of exclusive alleles (NEA), mean pairwise distance (MPD), normalized intra-group variability index (nSSWG) and mean Bruvo distance between the genotypes clustered within each group.
