Abstract：Sweet potato isan important food，feedand energy crop.China is the world’slargest producer of sweet potato，and sweet potato plays averyimportantrole in China’snationaleconomy.Inrecent years，with climate change and frequenttransportationofsweetpotato seedlings，theincidenceof sweetpotatodiseases hasbecomemoreandmore severe andnewdiseases continue toemerge，seriouslyaffecting theyieldandqualityofsweet potatoesandrestricting the healthy development of China’ssweet potato industry.The rapid development of molecular biotechnology has provided new technical supportand research ideas fordisease-resistant molecular breeding insweet potato.This review mainlysummarizes the research progress of sweet potato disease resistance-related genes andtheirfunctions inrecent years from the aspects of antifungal，bacterial，nematodeandviraldiseaserelatedgenes.Thisprovidesareferenceforfurtherresearchondiseasersist ance-related genes in sweet potatoes and molecular breeding for disease resistance.
