Table 1. Allelic richness (A_r) and gene diversity (expected heterozygosity, H_e) for the two SWF groups identified with admixture at K = 2 and the 7 genetic groups previously identified in Camus-Kulandaivelu et al. [10].

Group.Name	Population Size	Allelic richness (A_r)	Expected heterozygosity (H_e)
Andean	12	1.75	0.31
Caribbean	25	1.72	0.32
Corn Belt Dent	15	1.75	0.33
Pyrenees_Galicia_2	9	1.76	0.30
Italian Flint	17	1.66	0.29
Mexican	22	1.71	0.33
Northern Flint	37	1.52	0.27
W-SWF	129	1.72	0.27
E-SWF	65	1.68	0.29

A_r values were calculated using a rarefaction method as in [38], with 1000 resampling of 9 landraces without replacement in each group, except for the Andes group for which we obtained only 220 possible resampling of 9 landraces. We used a Wilcoxon signed-rank test to analyze statistical differences between peers of H_e (or pair of A_r) values estimated for the 9 groups. All comparisons for pair of H_e (and pair of A_r) were significant (p-value< 0.009); except for comparison between He of ITA and SWEF groups (p-value = 0.45) and comparison between A_r of Andean and Corn Belt Dent groups. E-SWF = East South-West France; W-SWF = West South-West France.
