The invention relates to the technical field of molecular markers, in particular to a tetraploid Chinese rose carotenoid content linked SNP molecular marker and application thereof. The molecular marker closely linked with formation and accumulation of the carotenoid of the Chinese rose is obtained, and the nucleotide sequence of the SNP marker is shown as SEQ ID NO.1; the polymorphic site is located at the 101th site of the sequence as shown in SEQ ID NO.1, and the polymorphism is A/G. According to the molecular marker sequence information, the target character can be screened in the seedling stage, the traditional cross breeding period is effectively shortened, and accurate and efficient China rose flower color molecular breeding is achieved. Through molecular marker-assisted breeding, the content of carotenoid in the Chinese rose petals is effectively increased, cultivation of novel yellow/orange Chinese rose varieties is promoted, natural derivative products such as plant essential oil and new food raw ma
