Abstract: Investigations were carried out on the wide cross of Chinese orchids and the germination of their hybrid seeds using the orchids of Cymbidiums, Phalaenopsis and Oncidium as materials. The results showed : (1) the fruit set ratios of combinations made with different Chinese orchid species were over 95%; (2) in combinations of Cym.sinense and Cym. hybrids , the fruit set ratios and the amount of seeds per fruit were different with the cultivars of Cym. hybrid and their reciprocal crosses; (3) the fruit set ratios were lower and the amount of seeds per fruit were less when crossing Chinese orchids with other genera orchids; (4) different kinds of hybrid seeds formed different kinds and amount of intermidiate propagule , the hybrid seeds from combinations of Cym.sinense and Cym. hybrids formed protocorm like body, while others formed rhizome; (5) about 10 000 seedlings were produced through protocorm like body and rhizome pathway; (6) the wide cross breeding of Chinese orchids and the hybrid seedlings production were discussed.
