Consistency of the QTL between clusters of environments for the WOSR (A) and AM-DH (B) populations. The QTL were detected for each population and trait using the single-environment model (6) and were counted for each cluster. The numbers in the intersections of the Venn diagrams indicate the numbers of common QTL between the given two, three or four groups. Dij14 (chart a) and Dij13 (chart b) were considered independent groups because they were not included in the clustering. Stars indicate potentially over-estimated numbers due to overlapping trials between clusters 1 and 2 (chart a) or clusters B and C (chart b)
