The invention belongs to the technology field of plant gene engineering, and relates to the field of preparation and application of molecular marker. The molecular marker originates from the ZmGA3ox21 gene section, which locates in the third chromosome of corn and controls the character of plant height of corn. The sequence of the nucleotide, which is used to separate and clone the ZmGA3ox2 gene, is represented by the SEQ ID NO: 1, and the cDNA sequence of the nucleotide is represented by the SEQ ID NO: 2. A molecular marker of corn plant height is obtained, and the nucleotide sequence of the molecular marker is represented by SEQ ID NO: 6-9. It has been proved by utilizing the map-based cloning method that natural variation of the gene can affect the number variation of corn plant height, and provoke the changes of length, expression level, and in-vitro active GA content of corn internodal cells. The natural variation of the gene does not affect yield and flowering phase related characters. It has been proved by the genetic analysis of dwarf mutant d 1-6016 that loss of large sections of the gene can cause dwarfing of corn plants.
