The invention relates to the field of plant DNA (deoxyribonucleic acid) molecular identification, in particular to an SSR (simple sequence repeat) molecular marker for identifying interspecific resources of East Asian chestnut plants, a method and application. The SSR molecular marker for identifying the interspecific resources of the East Asian chestnut plants comprises an SSR molecular marker CmSSR01, an SSR molecular marker CmSSR02 and an SSR molecular marker CmSSR03. The SSR molecular marker can effectively overcome the defect that it is difficult to accurately distinguish the germplasm of the Chinese chestnut from the germplasm of the castanea seguinii, the germplasm of the castanea henryi and the germplasm of the Japanese chestnut only through phenotypic characteristics during field sampling and in the seedling stage, and has very wide application prospects in molecular identification and genetic diversity analysis of germplasm resources of chestnut plants. 本发明涉及植物DNA分子鉴定领域，具体而言，涉及用于鉴定东亚栗属植物种间资源的SSR分子标记
