Principal component analysis. The PC analysis of 101 soybean lines was conducted using 2,593 SNP markers with MAF ≥ 0.3. The two-dimensional plot (PC1 vs PC2) shows that lines are assigned to two main groups according to their geographical origin. Arrows indicate the seven most resistant accessions in the whole panel.
