Abstract
The aim of the study was to characterize the collection of endangered Indonesian Vanda orchids based on morphological characters. The information obtained is useful for the conservation of germplasm and for the development of superior Vanda orchid breeding programs in the future. The research activity was conducted from May to November 2018 at the Biosciences Laboratory and Plant Laboratory - State Polytechnic Jember, East Java, Indonesia. The experimental design used in this study was a non factorial completely randomized design with three replications. The treatment in this experiment consisted of fourteen Vanda orchid species from various regions in Indonesia. Observation variables based on qualitative morphological characterization. The results of the experiment showed that the coefficient of similarity in morphological characters ranged from 0.33 to 1.00. The lowest value is found between Vanda Helfola and Arades. The results of the dendogram from grouping based on similarity coefficients are divided into two groups, namely the Vanda group consisting of all types of groupings at coefficients of 0.67 - 0.73 and Vanda groups which group at coefficients 0. 39
