BREEDING OF VANDACEOUS ORCHIDS: A STRATEGY TO CONSERVE ORCHID

Abstract

F1 genaration for the hybridization trial of Renanthera imschootiana × V. ampullaceua var. auranticum (100 %), Vanda testecea × V. ampullacea var. auranticum (100 %), Aerides odoratum × V. ampullaceua var. auranticum (100%), Vanda coerulescens × V. ampullaceua var. auranticum (40%) and Rhynchostylis restusa × V. ampullaceum var. auranticum (20%) were successfully germinated in ½ MS (Murashige and Skoog medium) medium. Survival rate of the transplanted plantlets of Vanda testecea × V. ampullacea var. auranticum in the polyhouse condition grew best on brick chips:charcoal pieces in 2:1 ratio with 100% after 30 days of culture. Fully acclimatized seedlings were reintroduced to its natural habitats. Hence, reproducible protocols for in vitro culture and hybrid production of this hybrid orchids have been established.
