The analysis revealed six major clusters corresponding to the origins of the progenies from previous cultivars. Figure 2 Principal component analysis (PCA) scatter plot of pairwise genetic distances among 267 progenies using 605 SNP markers The results on Table 2, showed the genetic variation among soybean progenies, these findings are consistent with the PCA results. High He and Ho values in P98Y11 and NA5909 indicate a broad genetic base suitable for intracultivar selection, while the low diversity in NS7000 (He = 0.047725; Ho = 0.032058), also reflected in its low dispersion in the PCA, may limit selection potential.
