A. bisporus is the fifth most cultivated mushroom in Korea, and approximately 10,757 tons were cultivated in 2015. The genetic diversity of collected strains in Korea and commercial cultivars was analyzed using inter-simple sequence repeat (ISSR) markers. ISSR markers known to be comparable among A. bisporus spp. were selected from various markers. Totally, 16 markers, namely the ISSR markers 807, 808, 810, 811, 834, 835, 836, 841, 842, P3, P8, P17, P22, P30, P38, and P39, were evaluated to discriminate between ASI 1110, 1114, 1115, 1238, 1246, 1365, 1366, and 1369 for selecting suitable markers in 16 markers. The ISSR markers P31, P38 and P39 exhibited various fingerprints that could help classify the strains in species. Using the three markers, genetic relationships among 39 strains, including commercial cultivars, such as SaeA and SaeYeon, were analyzed using the UPGMA method. The results of the analysis of the genetic relationships between commercial cultivars and collected strains in Korea confirmed that the commercial cultivars were different from the collected strains in Korea. These results suggested that the ISSR markers P31, P38, and P30 could be used for selecting the commercial cultivars of A. bisporus.
