Abstract

The invention discloses an SSR marker for identifying germplasm of prunus pauciflora, application and an identifying method, and belongs to the technical field of plant molecular marker assisted germplasm resource identification and breeding. The SSR marker 78A9-1 is used as a molecular marker, genome DNA of germplasm of prunus pauciflora and affinis specifies is extracted, a pair of SSR marker primers is used for PCR amplification, an amplified product is subjected to polyacrylamide gel electrophoresis, spectrum bands are read, and the statistical analysis is performed. The invention overcomes the defect that the germplasm of the prunus pauciflora cannot be identified accurately, and provides the SSR marker for rapidly and accurately identifying the germplasm of the prunus pauciflora. TheSSR marker has the advantage of quickly and accurately identifying the germplasm of the prunus pauciflora.

Description

technical field [0001] The invention relates to the technical field of identification and breeding of germplasm resources assisted by plant molecular markers, in particular to an SSR marker, application and identification method for identifying germplasm of Chinese cherry. Background technique [0002] Chinese cherry is a perennial woody fruit tree of the genus Cerasus in the family Rosaceae. It has been cultivated for 3,000 years. Its fruit has a strong flavor and bright appearance, and has extremely high nutritional, health and economic values. However, Chinese cherry is a polyploid species with high genome heterozygosity and long childhood. There are homonyms and different names with other closely related species of the genus Cherry, and interspecies hybridization is prone to occur among species of the genus Cherry. The qualitative genetic composition is difficult to ascertain. [0003] Plant species identification is divided into field trait identification and molecular...
