Interspecific hybridization of Dendrobium mirbelianum x D. nindii or D. discolor, in vitro seed germination, seedling growth and plantlet acclimatization

Abstract. Maulida D, Yusnita Y, Hapsoro Agustiansyah A, Karyanto A. 2023. Interspecific hybridization of Dendrobium mirbelianum x D. nindii or discolor, in vitro seed germination, seedling growth and plantlet acclimatization. Biodiversitas 24: 3004-3011. Gaudich. (P1), W.Hill (P2), discolor Lindl. (P3) as a parent crossing are potentially resulting new type orchid the novel breeding achievement. This study aimed to identify compatibility evaluate most effective efficient media for hybrid germination growth. The consisted three experiments, namely interspecific (experiment 1), 2), seedlings 3). first experiment was conducted by simple modified line×tester mating design, all experiments used completely randomized with five replications second third experiments. presented emerging pods, but only seeds from cross its reciprocal that potent germinate tested result. showed FF+tryptone best indicated highest heaviest after 8 months sowing. All crossings resulted however, able media. Foliar fertilizer is recommended germinating seeds,
