The application discloses a parent-offspring identification primer group and method of Prunus. The parent-offspring identification primer group of Prunus disclosed by the application is composed of 30 single-stranded DNAs shown in sequence 1 to sequence 30 in a sequence list. The primer group and method of the application can identify the genetic relationship of Prunus armeniaca, Prunus dulcis and their offspring, establish a parent-offspring identification system, and are simple to operate. The primer group and method of the application can quickly obtain genetic information of Prunus parents and offspring and determine the source of the offspring, can early determine and retain hybrid offspring between Prunus armeniaca and Prunus dulcis at the seedling stage, which is beneficial to quickly determine the true outcrossing seedling at the seedling stage, thereby removing hybrid offspring caused by natural pollination and eliminating the hybrid offspring at the seedling stage, so as to save land resources, reduce the identification cost in the later period, speed up the breeding process, and also provide a reference for parent-offspring identification of other fruit plants.
