Figure 8.

Two dimensional scatter graphs of eigenvalues from principal component analysis. The first two significant eigenvalues from principal component analyses performed with SAS software PRINCOMP procedure are plotted against each other to show resolution within species or classes. a) Eigenvalues significant at P < 0.0001 from principal components one and two are plotted against each other and show clear resolution of species. b) Eigenvalues one and three were both significant at P < 0.0001 and were plotted against each other. The y-axis was altered to show clearer resolution in non-oil genotypes. Batavia and Leafy classes show distribution through the scatter plot similar to that seen in Figure 7a and 7b
