Abstract: The well-spread and clear mitotic metaphase chromosomes of ginger were obtained. The karyotype analysis showed that ginger was diploid (2n=2x=22). The length of ginger’s chromosome was 128.02μm and the average length was 5.82μm. The ratio of the longest chromosome to the shortest one is 2.06:1, and the arm ration of 45.5% chromosomes was over 2, so that the karyotype is 2B. The karyotype formula is 2n=2x=22=8m+12sm+2st.
