| Abstract | The intraspecific and interspecific crossability of some Eulophia spp. was assessed. It was found that the selfing percentages of E. andamanensis, E. flava, E. graminea, E. macrobulbon and E. spectabilis were 100.00, 100.00, 86.36, 86.67 and 92.30% respectively. The fruit set percentages of E. flava ? E. spectabilis and E. spectabilis ? E. flava were both 100.00%, while those of E. spectabilis ? E. andamanensis and E. spectabilis ? E. macrobulbon were 75.00 and 100.00% respectively. However, the fruit set of reciprocal crosses did not occur. The interspecific hybridisation between E. spectabilis and E. graminea was not successful. The genetic relationship of a number of Eulophia species was determined by random amplification of polymorphic DNA (RAPD) analysis. A total of twelve Eulophia samples __eight from E. spectabilis and one each from E. andamanensis, E. flava, E. graminea and E. macrobulbon__from five species could be separated into two groups by a combination of three primers. The first group consisted of E. andamanensis and E. graminea, and the others comprised E. flava, E. macrobulbon and all E. spectabilis specimens. The genetic data in this study correspond with the morphologically based classification at the species level. |
