The invention relates to an SNP molecular marker and application thereof. The molecular marker is located on a roselle anthocyanin synthetase gene ANS, the base of purple-fruit roselle with high anthocyanin content is A, and the mutant base of white-fruit roselle with low anthocyanin content is G. The molecular marker DYSNP1 is closely linked with the character of the roselle purple fruit, the anthocyanin content of a roselle sample can be reflected by detecting genetic information of the roselle sample at the DYSNP1, and the molecular marker is of great significance to genetic breeding and identification of germplasm resources. 本发明涉及一种SNP分子标记及其应用，所述分子标记位于玫瑰茄花青素合成酶基因ANS上，高花青素含量的紫色果玫瑰茄碱基为A，低花青素含量的白色果玫瑰茄变异碱基为G。本发明所述分子标记DYSNP1与玫瑰茄紫果性状紧密连锁，通过检测玫瑰茄样本在DYSNP1处的遗传信息可反映该样本的花青素含量，对于遗传育种和种质资源的鉴定具有重要意义。
