Twelve RAPD primers and four ISSR primers generated clear, distinct and reproducible bands. Total genomic DNA extracted from fresh leaves of <i style="mso-bidi-font-style:normal">in</i> <i style="mso-bidi-font-style: normal">vitro</i> regenerated as well as mother plants was used for developing RAPD and ISSR profiles. All RAPD and ISSR profiles from micropropagated plants were monomorphic and similar to those of the field grown mother plants.<span style="font-size:11.0pt;mso-bidi-font-size:9.0pt;font-family:" times="" new="" roman";="" mso-fareast-font-family:"times="" roman";letter-spacing:-.2pt;mso-ansi-language:="" en-gb;mso-fareast-language:en-us;mso-bidi-language:hi"="" lang="EN-GB"> <span style="font-size:11.0pt;mso-bidi-font-size:9.0pt;font-family:" times="" new="" roman";="" mso-fareast-font-family:"times="" roman";letter-spacing:-.2pt;mso-ansi-language:="" en-gb;mso-fareast-language:en-us;mso-bidi-language:ar-sa"="" lang="EN-GB">No genetic variation was detected within the micropropagated plants in comparison to their mother plants.
