Abstract
Nineteen populations of G. tournefortii were collected from various regions in Jordan represented two eco-geographic systems.
The population size ranged between 1 to 5 plants m‑2 and the highest plant height was 50 cm.
RAPD and SSR markers were used to assess genetic diversity of G. tournefortii populations.
Twenty four primers were used to amplify 51 bands out of which 42 (82.4%) were polymorphic.
Cluster and principle coordinate analyses (PCoA) were able to produce three major groups and four subgroups and the genetic distance was 8.58. Analysis of molecular variance (AMOVA) revealed differences among groups accounted for 38.6% of the total variation, whereas differences among populations and within populations were 40.9 and 20.5%, respectively.
