Morphological characterization of natural orchids Phiaus spp.

Phaius spp. is an orchid plant that has a large plant size with dark and striking flower color which is an attraction for Phaius spp. Morphological characterization of orchids is needed for the preservation of germplasm and selecting a variety of natural orchid germplasm that has superior plant and hash surface properties to be used in crossing. The study aims to identify the quantitative morphological character of 5 species Phaius spp. The materials used were Sulawesi Phaius tankervilliae and P. indigoferus, Papua was P. montanus, and Bali P. amboinensis and P. callosus which were the collection of the Bogor Botanical Garden. The result showed that the dendogram based on similarity the five species in the similarity of 1.32 produces two groups, the first group consists of P. amboinensis, P. indigoferus, P. montanus. The second grup consist of P. callosus and P. tankervillae. Genotype P. amboinensis and P. indigoferus showed similiraity (87%) compared to the other genotypes and have opportunity to be used as parents for crossing.
