ISSR Molecular Markers in Loquat: Research Progress

The traditional marker techniques of loquat have some limitations, such as less information, limited sampling site, unable to get early identification, human factors affecting the identification results. ISSR is favored by researchers because of high polymorphism, low experimental cost, relatively simple operation, high stability and co-dominance. This paper summarized the principle, advantages and disadvantages of ISSR, and summarized the progress of ISSR in loquat species identification, genetic variation analysis, classification, and fingerprint construction. It is found that the application of ISSR in loquat is less and the research depth is not enough. In the future, we believe that ISSR can be an indispensable molecular marker technology in loquat breeding research by improving the accuracy of ISSR, extending the depth and breadth of ISSR in loquat, strengthening the joint application of ISSR, and promoting the cooperation and communication between research teams.
