Abstract
Climate change can potentially lead to reducing biodiversity, including orchids. One of the efforts to increase the biodiversity of orchids is through the crossing. This study aimed to determine the morphological characters of plants resulting from interspecific crosses between Dendrobium bigibbum from Maluku and Dendrobium liniale from Papua, also to compare them with the characters of their parents. In this study, morphological characterization was carried out on 14 accessions, 3 male parent accessions, 3 female parent accessions and 8 F1 offspring accessions. Characterization was carried out based on 30 characters, including stem, leaf, flower, pseudobulb, and root types. The research was conducted in two places, the identification of the parents was carried out at Indonesia Research Institute Botanical Garden Conservation Center in Bogor, Indonesia, while the identification of hybrids was carried out in Karangploso Village, Karanganyar Regency. Cluster analysis was performed using NTSYSpc version 2.02i program with the UPGMA SimQual function method. The results showed differences in leaf and flower morphology between accessions that were observed including size, shape, pattern, and color of the petals and sepals, but the shape and size of the pseudobulbs, color, size and shape. However, leaves tend to resemble one another.
