Figure 4

Neighbour joining tree among Pre-Rif populations based on genotypic data. Populations are labelled by the name of the variety they belong to, and coloured according to their zone of origin: red for ZN1, blue for ZN2, green for ZN3 and light blue for ZN4. The Moroccan checks are coloured in yellow. Horizontal lines separate the five clusters discussed in the text. Each cluster is identified by a letter. The pie charts depict the composition of each cluster in term of spike-type and stature classes of populations. Bootstrap values are reported when higher than 40%.
