Figure 2
Bayesian clustering analysis (STRUCTURE) of the 793 Globodera rostochiensis individuals from the 22 populations collected in different continents. Assignment probabilities of individuals are presented for K = 3, i.e., the most likely number of clusters statistically determined using ΔK method (bottom-left graph). On the bottom-right graph, each vertical line represents an individual for which the genetic assignment is partitioned into three clusters, represented by three colors (cluster 1 in green, cluster 2 in yellow and cluster 3 in red), and vertical white lines separate each of the 22 populations. The map at the top shows the geographical location of the 22 G. rostochiensis populations and their membership proportion of clusters.
