Figure 3.

Genetic similarity of Siwa date palms based on neighbor‐joining tree reconstructed from Nei's genetic distances. On the right of the tree, colored vertical lines connect samples of the same named types. Nodes supported by bootstrap values > 80% are indicated by black dots. The tree has been rooted with two Phoenix reclinata (not shown). The different samples of a true‐to‐type cultivar are expected to aggregate together, while samples of ethnovarieties would form different lines of clones, and samples of local categories would be scattered across the tree, denoting their lack of relatedness
