RAPD analysis of some species in the genus Vanda (Orchidaceae)

Abstract

The genetic closeness of various species of Vanda was determined using random amplified polymorphic DNA (RAPD). Strap-leaved Vanda species (including Vanda sanderiana) and Ascocentrum miniatum were more closely related to each other than to the terete-leaved Vanda species studied. RAPD analysis supports the suggestion that terete-leaved Vanda teres and Vanda hookeriana be classified in the separate genus Papilionanthe and that Vanda sanderiana should remain in the genus Vanda.
