Molecular Fingerprinting of jojoba [Simmondsia chinensis (Link)‎ Schneider] clones with inter-simple sequence repeat (ISSR)‎ markers

الملخص EN

Jojoba (Simmondsia chinensis [Link] Schneider) is a crop of high economic interest that is grown for the excaeptional quality of its seed oil as a medicinal and industrial vegetable oil.

We have taken advantage of the large variation commonly shown by inter simple sequence repeat (ISSR) to assess the genetic diversity among jojoba clones.

The variation of DNA was analyzed with the use of an ISSR primers generated by PCR.

The number of amplification bands per primer varied between 0 and 11.

Analysis of the six ISSR primers among jojoba clones in this study generated 41 bands.

Over 85.4 % (35 bands) were found to be polymorphic in jojoba clones using ISSR.

The genetic similarity coefficients among all jojoba ranged from 0.41 to 0.71.

The genogram constructed with UPGMA analysis revealed two main clusters.
