Abstract. Hartati S, Samanhudi, Manurung IR, Cahyono O. 2021. Morphological characteristics of Phaius spp. orchids from Indonesia. Biodiversitas 22: 1991-1995. Orchid is one of the ornamental plants with great economic value in various communities. Characterization and grouping of several orchid species can be used in breeding efforts to obtain hybrid with the desired traits. This study is aimed to characterize the morphological appearance of Phaius orchids and to cluster the species based on their similarity in morphological characteristics. Five species of Phaius (P. tankervilleae, P. indigoferus, P. montanus, P. amboinensis, and P. callosus) of the collection of the Bogor Botanical Garden were observed based on 30 morphological characters including the characters of stems, pseudobulbs, leaves and flowers. The data obtained were converted into binary data and computed using the Numerical Taxonomy and Multivariate Analysis System (NTSYS) Spc 2.02 program to produce dendrogram. The results show that based on the morphological characterization of the five species of Phaius spp., they have similarities from 63% to 80%. Among the five Phaius species, P. amboinensis, P. tankervilleae, and P. montanus had 80% similarity and can be used as parents for crossing.

Abstract. Hartati S, Samanhudi, Cahyono O. 2022. Short Communication: Morphological characterization of five species of Dendrobium native to Indonesia for parent selection. Biodiversitas 23: 2648-2654. As one of the most plentiful orchid genera, Dendrobium has a potential genetic resource for crossing programs. Morphological characterization is an important step in determining genetic relationships among orchid species in the same genus. The research aims to identify the morphological characteristics of five species of Indonesian Dendrobium in order to assess the potential cross elder candidates. The materials used in this study were D. mirbelianum Gaudich., D. lamellatum (Blume) Lindl., and D. anosmum obtained from Bogor Botanic Gardens; and D.bracteosum Rchb.f. and D. purpureum obtained from Klaten Speci Gardens. This study recorded 30 morphological characters of Dendrobium studied. There were 23 out of the 30 identified morphological characters (76.67%) that showed varying characters in flowers, leaves, pseudobulbs, and roots. Based on the cluster analysis, five species of Dendrobium are separated into two clusters and cluster division does not correlate with the section of Dendrobium. The species with the highest similarity coefficient has the potential to be used as parental in crosses. Dendrobium lamellatum and D. anosmum have the highest similarity coefficient of 0.80 and are the most potential as parental species for crossing, followed by D. bracteosum and D. purpureum with a similarity coefficient of 0.70.
