Abstract: The chromosome number and karyotype of five native species and one hybrid cultive of Cymbidium was studied by applying fingertip pressing method. The results showed that the C. floribundum Lindl . 2n=2x=40=36m+4sm ;C. dayanum Rchb. 2n=2x=40=36m+4sm ;C. bicolor Lindl. subsp.obtusum Du Puy et Cribb 2n=2x=40=40m(4SAT);C.insigne Rolfe 2n=2x=40=2M+36m+2sm;C.eburneum Lindl. 2n=2x=40=32m+8sm ;C.golden Elf.‘Sundust’2n=2x=40=34m+6sm(2SAT). Aslo we has discussion the relationship and the role in the orchid breeding of these Cymbidiums.
