Summary:T. arundinaceum（Tripidium arundinaceum） is an important wild germplasm resource of sugarcane. It is one of the important ways of sugarcane breeding to infiltrate its lineage to improve sugarcane resistance. Karyotyping of the hybrids between sugarcane and T. arundinaceum is beneficial for the efficient utilization of its various superior traits. In this study, we used species-specific primers for identifying the authenticity of the high generation hybrids between sugarcane and T. arundinaceum, and typed the sugarcane and T. arundinaceum chromosomes by fluorescence in situ hybridization to investigate the inheritance, segregation, and structural characteristics of T. arundinaceum in the offspring. These results indicated that 30 clones were true progeny with 1–10 T. arundinaceum chromosomes, indicating that their progeny population basically obeyed n+n mode of chromosome inheritance that accounted for 60% in the entire true progeny population. The probability of recombination at the chromosomal level between T
