The invention provides an Agrobacterium tumefaciens strain for promoting callus of harvested potato tubers, which is preserved in China General Microbiological Culture Collection Center (CGMCC), and the preservation number of the Agrobacterium tumefaciens strain is CGMCC No: 24362. The Agrobacterium tumefaciens strain provided by the invention is separated from a self-callus potato tissue, and has the advantages that the propagation is fast, the strain is easy to collect, the post-harvest tuber is easy to treat, the generation speed of a tuber callus epidermis sealing layer (namely secondary peridermis which is mainly composed of a cell layer of lignin, polyphenol cork grease and polyester cork grease) is accelerated, and the survival rate of the tuber callus epidermis sealing layer is increased. Therefore, the weight loss speed of tubers and the expansion of fusarium infected disease spots are reduced. 本发明提供一株促进采后马铃薯块茎愈伤的根癌农杆菌Agrobacterium tumefaciens，其保藏于中国微生物菌种保藏管理委员会普通微生物中心，保藏编号为CGMCC No：24362。本发明所涉及的根癌农杆
