Figure 3. Clustering of 44 candidate plus trees (CPT) according to the pod and seed traitsRemarks: The values on the edges of the clustering represent p-values (%). The redcolored values show the AU (approximately unbiassed) p-values while the green-colored ones mean the BP (bootstrapt probability) values. Four red-colored rectangles in a bootstrap probability clustering represent clusters with the AU larger than 95%, which means that the results show rather strong correlation by the data.
