Abstract

Random amplified polymorphic DNA (RAPD) markers were used to verify the clonal fidelity of two micropropagated Drosera species, D. anglica and D. binata, which were regenerated by adventitious budding from leaf explants and shoot tips, respectively. Twenty arbitrary decamers were used to screen 15 randomly selected plantlets of each species. No genetic variation was detected among D. binata regenerants, whereas a 0.08% polymorphism frequency was estimated for D. anglica plantlets. These results indicate that the regeneration of plants through shoot-tip culture is a low-risk method for generating genetic variability, whereas material regenerated through leaf explants requires further verification.
