In addition,the average yield of ‘Wongam’ was 359 kg/10a, which was 127% higher than that of G. uralensis. It exhibits resistance to brown spot disease,as well as a to lodging. The glycyrrhizin and liquiritigenin content of ‘Wongam’ are 3.96% and 0.8%, respectively, which meets the KoreanPharmacopoeia Standards.
