The invention belongs to the field of genetic engineering in molecular biology, and specifically relates to a strawberry anthocyanin-related gene FvMYB17 and an application thereof. A nucleotide sequence of the FvMYB17 is shown in SEQ ID NO:1, and the amino acid sequence is shown in SEQ ID NO:2; the gene is indicated to have the function of promoting arabidopsis thaliana anthocyanin synthesis through research. A theoretical basis and technical means are provided for regulation of fruit color by using a genetic engineering technology, and great application value is achieved.
