“…As the most useful DNA marker system for variety identification and germplasm management, SSR molecular markers have several advantages due to their abundance, high polymorphism, multiple alleles, co-dominance, low-cost, and the ease of assay by PCR [ 17 , 18 ], which have been applied extensively in genetic analysis, such as the analysis of population structure and genetic diversity [ 19 , 20 ], QTL mapping [ 21 , 22 , 23 ], marker-assisted selection breeding [ 24 , 25 , 26 ], and DNA fingerprinting [ 27 , 28 ], etc. SSR molecular markers are rarely used in M. incana [ 11 , 14 ], which is largely due to the fact that SSR molecular markers have not been developed in M. incana . Early development methods for SSR tagging suffered from cumbersome operations, low success rates and high-costs, or were limited by the information in public data.…”
