“…The information can be a reference for crossbreeding to obtain new varieties. A study based on qualitative studies on Phaius orchids showed 0.80 morphological similarities, namely P. amboinensis, P. tankervilae, and P. montanus (Hartati et al 2021a). Based on quantitative characterization, Hartati et al (2021b) reported that P. indigoferus and P. amboinensis performed 0.87 morphological similarities.…”

“…Unfortunately, only several species of Dendrobium native to Indonesia have been characterized, such as Indraloka et al ( 2019) have characterized 10 species of Dendrobium and Aprilianti et al (2021) researched Dendrobium seed morphology. Some researchers have studied the morphological characterization of other orchids genera, such as Phalaenopsis (Fauziah et al 2014;Pangestu et al 2014), Vanda (De et al 2015b), Dendrobium (Hidayati et al 2016), and Phaius (Hartati et al 2021a). Therefore, this research aims to characterize the morphology of five species of Dendrobium native to Indonesia in order to assess the potential parental candidates for crosses.…”

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.

“…The coefficient similarity of (2) Phaius montanus and (3) Phaius collasus are 0.48. This is evident from Hartati's research (2020) that morphologically the Phaius amboinensis orchid and the orchid Phaius tankerville have a similarity of 80% and are divided into 2 clusters [28]. The more similar the morphology of the orchid, the higher the possibility of genetic similarity.…”

Phaius spp live in tropical forests with high humidity due to deforestation, which has resulted in the extinction of many endemic orchid species, especially orchids Phaius spp, so it needs to be conserved through a plant breeding program. There are not many research reports on the genetic diversity of orchids Phaius spp, even though the study of genetic diversity plays an important role in plant breeding programs and genetic conversation. This study aims to determine the genetic diversity of Phaius spp. This research was carried out using molecular markers RAPD (Random Amplified Polymorphic DNA). DNA from Phaius spp was extracted and then amplified by PCR using 6 RAPD primers. The results of this study found that four species of orchids of the genus Phaius spp (Phaius tankervillae (1); Phaius montanus (2); Phaius collasus (3); and Phaius amboinensis (4)) amplified using 6 RAPD primers to produce 37 DNA bands with a size of 250-1600 bp, and produce 100% polymorphic bands The genetic similarity coefficient of the 4 orchid species ranges from 0.19-0.53 and the genetic variability ranges from 47%-81%.

“…Knowledge of plant morphology also has an important role as the basis for determining breeding program strategies, as stated by Rêgo et al (2020) on the ornamental foliage plant of the genus Sansevieria. In its application to ornamental plants, Hartati et al (2021), based on the characterization of five species of Phaius orchids, noted that morphology was important in selecting suitable parents for experimental crosses to obtain hybrids with desirable traits.…”

Abstract. Permata DA, Susandarini R. 2021. Morphological diversity and phenetic relationship of wild and cultivated Begonia based on morphology and leaf venation. Biodiversitas 23: 928-937. Begonia is an ornamental plant with intense cultivation and hybridization practices because of the uniqueness and beauty of its leaves. Begonia with a very large number of species is interesting to study, especially because Indonesia is one of the resource centers of this genus diversity as indicated by the increasing number of new species found every year. This study aimed to explore the morphological diversity of wild and cultivated Begonia and reveal the phenetic relationships of the species and hybrids based on morphology and leaf venation patterns. In this study, we used 19 Begonia samples belonging to five species collected from their natural habitat and 14 species and hybrids obtained from the nurseries. Morphological observations of living specimens and examination on microscopic slides of cleared leaf resulted in 28 characters which were used to determine phenetic relationships using cluster analysis. The high variability of leaf venation patterns described in this study disclosed the micromorphological diversity of Begonia which has not been widely exposed. The results of morphological observations showed high variabilities in leaf color, leaf shape, and petiole color. The results of cluster analysis and principal component analysis indicated that the grouping of species was mainly determined by the existence of trichomes on leaf surfaces and petiole, leaf venation pattern, leaf variegation, and leaf shape. The grouping of species resulting from cluster analysis can be used in the selection of potential parents to produce new Begonia hybrids through crossing experiments.
