Principal components analysis (PCA) of agronomic traits for 59 Argentinian durum wheat genotypes. Traits correlation matrix is symbolized as vectors in A. Distribution of allelic variants at Rht-B1 and Ppd-A1 loci are shown in B and C, respectively. Colors represent the different groups from STRUCTURE in D. YLD grain yield, HI harvest index, BPP aerial biomass, GPC grain protein content, PH plant height, HD heading date, TKW thousand kernel weight, GNP grain number per plant, GNS grain number per spike, GNs grain number per spikelet, sS spikelets per spike, SP spikes per plant.
