“…Among the many molecular marker systems, in particular, the SSR marker system has provided useful information for the analysis of genetic diversity and relationships, population structure, genetic mapping (construct linkage maps), and association mapping in many crop species because of high reproducibility, allelic variation, codominant nature, and abundant crop genomes [ 22 , 24 , 27 , 30 , 31 ]. Recently, in the Perilla crop, SSR primer sets have been developed by many researchers [ 32 , 33 , 34 , 35 , 36 ]. They have successfully analyzed genetic diversity and relationships, population structure, and association mapping among the accessions of cultivated and weedy types of Perilla crop [ 4 , 5 , 26 , 34 , 36 , 37 , 38 , 39 ].…”
