Sampling locations and distribution of chloroplast DNA haplotypes of 18 populations of wild radish sampled in Japan.

<p>The pie charts indicate the haplotype frequencies and are color-coded, as for the parsimony network. Population numbers 1–18 correspond to those of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0135132#pone.0135132.t001" target="_blank">Table 1</a>.
