Abstract: This paper reported the DNA Dot-blo tting analyse on the progenies(2n=18), which seperated from M14(2n=19), the monosomic addi tio n lines of Beta vulgaris with high transmission rate near 100%. The probe 1054 was labeled with DIG Random Primed DNA Labeling method. Among total 80 progenies, 19 were proved to be translocation line with the fragment of chromosome from Beta corolliflora. Further study are needed to confirm if these translocation lines have apomixis genes.

Key words: apomixis gene, dot-blotting, translocation line
