摘　　要：Chromosome specimens of sugarcane, Erianthus fu/vus and their progenies were prepared with wall degradation hypotonic method to analyze the karyotypes of parents and Fl, F2 hybrids. The results showed that most chromosomes of experimental materials are median region （m） chromosomes, while only a small amount of chromosomes are submedian （sm） chromosomes. The karyotype of YAU04/102 belongs to 2C type, while other materials belong to 2B type. In addition, the karyotypes of hybrids are asymmetrical and the chromosomes of hybrids show an evolutionary trend compared with parental chromosomes.Chromosome specimens of sugarcane, Erianthus fu/vus and their progenies were prepared with wall degradation hypotonic method to analyze the karyotypes of parents and Fl, F2 hybrids.
