PCA morphology-based relationships between accessions.

<p>A total of 52 <i>S. melongena</i> accessions from China (white squares), Spain (grey triangles), and Sri Lanka (black circles) (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041748#pone-0041748-t001" target="_blank">Table 1</a>) were morphologically evaluated with 28 morphological traits (see text and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041748#pone-0041748-t002" target="_blank">Table 2</a>) and were represented on the two first components (PC1 and PC2) of the principal components analysis (22.9% and 16.2% of the total variation explained by the first and second component, respectively).
