Provided are a parthenogenetic haploid induction gene DMP and an application thereof. The parthenogenetic haploid induction genes AtDMP8 and AtDMP9 are cloned from. Experiments have shown that mutations of AtDMP8 and AtDMP9 can produce parthenogenetic haploid inducibility, to enable dicotyledonous crops to be induced to produce haploids via parthenogenetic means. The present invention was further verified in tomatoes, and it was also found in tomatoes that the mutation of SlDMP can produce parthenogenetic haploid inducibility. The invention lays an important foundation for broadening the application of haploid breeding technology on dicotyledonous plants and revealing the biological mechanism of parthenogenetic haploid production. Given the universality of the utilization of haploid breeding technology in the current breeding industry, the invention has very wide application space and market prospects.
