An assessment of genetic fidelity of micropropagated plants of Chlorophytum borivilianum using RAPD markers

Rapid micropropagation was achieved in Chlorophytum borivilianum Santapau and Fernandes using shoot base as explants. Multiple shoots were induced on Murashige and Skoog's (MS) medium supplemented with 3.0 mg dm(-3) 6-benzylaminopurine, 0.1 mg dm(-3) 1-naphthaleneacetic acid, 150 mg dm(-3) adenine sulphates and 3 % saccharose. Rooting was readily achieved upon transferring the shoots onto half strength MS medium supplemented with 0.1 mg dm(-3) indolebutyric acid and 2 % saccharose. Micropropagated plantlets were hardened in the greenhouse and successfully established in soil. Random amplified polymorphic DNA (RAPD) markers were used to evaluate the genetic stability of the micropropagated plants. Thirty one arbitrary decamers were used to amplify genomic DNA from in vitro and in vivo plant material to assess the genetic stability. All RAPD profile analysis from micropropagated plants was genetically similar to mother plants.
