Dendrogram obtained with the simple matching (SM) similarity coefficient pair group method with arithmetical average clustering algorithm from 1090 AFLP markers for 200 olive accessions. The value on the dendrogram gives the stability of nodes estimated with a bootstrap procedure (no number indicates support less than 10%). Bar graph showing genetic diversity structures for the accessions of O. europaea L. as assessed using STRUCTURE software. Each group is represented by a different color (blue, red and green)
