Abstract: Tetrasomic Ⅳ, Ⅷ and Ⅸ were discovered from primary trisomic population of fox tail millet, Kargotype analysis of the three kinds of tetrasomics showed that th eir chromosome numbers were invariably 2n+2=20. The two additional chromosomes o f the tetrasomics formed a stable quadrivalent with two o
