Abstract: Hybridization among Cymbidium sinense, C. ensifolium, C. aloifolium, C. lancifolium and hybrid Cymbidium were carried out. In 52 crosses, the ratio of distinct ovary enlargement to seed capsule development was 86.5%, but only 32.7% of crosses, whose seed capsules developed after 4 months. Hybrid plants of 19.2% crosses were obtained by embryo culture. There are obvious differences in hybridization between Cymbidium sinense×hybrid Cymbidium and hybrid Cymbidium×C. sinense.

Key words: Cymbidium, Hybrid Cymbidium, C. sinense, C. ensifolium, C. aloifolium, C. lancifolium, Hybridization
