A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. Crossbreeding, sometimes called "designer crossbreeding", is the process of breeding such an organism, often with the intention to create offspring that share the traits of both parent lineages, or producing an organism with hybrid vigor. While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism.

The application discloses a molecular marker and specific primers and an identification method for identifying Takifugu obscurus, Takifugu poecilonotus and hybrid Arlea japonica. The application can realize multiple test results through one-time PCR, and simultaneously complete the rapid identification of the three species of Takifugu obscurus, Takifugu poecilonotus and hybrid Arlea japonica. The application provides a fast and accurate identification method for Arlea japonica variety identification, solves the problems of difficult naked-eye differentiation and low operation accuracy of morphological feature differentiation, and realizes the characteristics of easy result judgment, high conservation, high accuracy and the like. The application provides technical support for variety identification and parent selection of the special economic fish, provides a train of thought for further carrying out genetic scientific research of hybrid Arlea japonica, and is favorable for promoting the vigorous development of the hybrid Arlea japonica breeding industry.
