<p>Graphical visualization of the epistatic interactions observed among different loci controlling seed and seedling quality phenotypes. The 12 chromosomes are represented as different circle segments, and their sizes are proportional to the corresponding genetic sizes measured in cM. The colour of the lines indicates the trait for which the epistatic interaction was observed <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043991#pone.0043991-Arends1" target="_blank">[86]</a>.</p
