 ABSTRACT

Micropropagated plantlets of two orchid cultivars namely Dendrobium ‘Sonia’ and Dendrobium nobile var. 'Emma White’ were analyzed for genetic fidelity by RAPD markers. The in vitro raised plantlets were maintained repeatedly by in- vitro subcultures. Out of 20 primers utilized during present investigation, amplification was achieved with all primers. But reproducible amplification protocol was standardized only for 8 primers namely, OPL-02, OPL-03, OPL-8, OPL- 11, OPN-01, OPN-06, OPN-09, OPN-10. The amplified products were monomorphic across all the selected micropropagated plants and were similar to the mother plant. So, the RAPD analysis of micro propagated plant along with their original cultivar with eight decamer primers did not showed any variation. Hence, it confirmed the genetic uniformity of micropropagated plantlets in the present study.
