Provided is a polynucleotide for identifying a male or female Ginkgo biloba plant, comprising or consisting of the following sequence: 1) the nucleotide sequence represented by SEQ ID NO: 5; or 2) a complementary, degenerate or homologous sequence of the sequence represented by SEQ ID NO: 5; or 3) a polynucleotide hybridizing to the nucleotide sequence represented by SEQ ID NO: 5 under stringent conditions or a complementary sequence thereof; 4) the coding sequence of any one of the sequences of the above 1)-3); or 5) a nucleotide sequence being identical to more than 10 bp contiguous nucleotides in any one of the sequences of the above 1)-4). The polynucleotide provided herein is unique to a male Ginkgo biloba plant, and it may be used to identify a male or female Ginkgo biloba plant; this identification method has the advantages of stable and accurate results, good repeatability and fast detection, thereby providing the basis for identifying a male or female Ginkgo biloba plant by molecular markers.
