Cloud ear mushroom (Auricularia polytricha: aragekikurage in Japanese) is known as an excellent edible mushroom in Japan. Most domestically distributed cloud ear mushroom is imported. Recently, clarification of risks of imported edible mushrooms has raised consumer awareness about food safety. Consequently, domestic production is attracting attention, although breeding of new cultivars has stagnated. In Tottori prefecture, cultivation of this mushroom is being promoted mainly by the Japan Kinoko Research Center Foundation. Several reasons improvement of conventionally used cultivars is needed include light color and low yield. Cultivars No. 1 (TMIC 36441) was selected from five candidates in this study as a new cultivar that improved these traits. This cultivar was given the final designation "KinjinAP1". For the purpose of protecting breeder's rights, we developed cultivar identification markers CI-1 and CI-2, which distinguish the new cultivar selected in this study from 3 domestic cultivars, and 39 dried mushrooms on the market (13 domestic and 26 foreign products).
