Abstract Potato soil-borne diseases are becoming increasingly serious．Rapid detection on pathogenic
bacteria is an important basis for early diagnosis，predictive monitoring，and comprehensive control of the
diseases．This paper comprehensively compared the characteristics of conventional PCR，nested PCR，realtime
quantitative PCR，multiplex PCR and LAMP technology in sensitivity and specificity，and evaluated their
merits and demerits in detecting potato soil-borne diseases．The paper also summarized the primer information
of various diseases detection reports and advantages of this detection system．At the same time，the paper
prospected the applying future of each technology，aiming at obtaining an overall understanding about the rapid
detection methods and their development tendency on potato soil-borne diseases．
