From: Spatial optimization of genetic thinning in seed orchards
The Varmin criterion (Y-axis) of the seed orchard Doubrava in the Czech Republic following the genetic thinning, with 0–40% ramets removed from the orchard (proportion selected, X-axis). The number of remaining trees (grafts) is provided on the secondary X-axis. The distribution of clonal sizes is shown on the secondary Y-axis
