Population structure analysis for 59 Argentinian durum wheat genotypes assessed by 3565 SNP. (A) Barplot of the genotypes at K = 3 from STRUCTURE software, (B) delta K values for the different genetic groups, (C) Principal Coordinate Analysis (PCoA) and (D) Rht-B1 and Ppd-A1 allele frequencies in each group defined by STRUCTURE. Colors in the PCoA plot for each genotype correspond to the STRUCTURE results at K = 3. M indicates the mixed group (% of membership < 0.6), in PCoA plot the mixed genotypes were colored in black.
