英文摘要: Chromosome numbers and karyotypes of three Colocasia species from Yunnan were reported. Their karyotypes were as follows: 2n = 2x = 28 = 22m (1 sat) + 6sm for C. gongii; 2n = 2x = 28 = 20m + 8sm for C. gaoligongensis; 2n = 2x = 28 = 20m + 8sm for C. gigantea. Common karyomorphological characteristics of three species examined were: (1) the simple chromocenter type of the resting chromosomes and the proximal type of the mitotic prophase chromosomes; (2) the chromosome number 2n = 28 and (3) the chromosome complement of m- and sm-chromosomes. x = 14 was confirmed as the basic chromosome number of Colocasia. There were differences among species in the number of in- and sm-chromosomes as well as satellite.
