Licorice is a semi-desert plant that is difficult to grow under Korean climatic conditions. In order to increase the adaptability of licorice in Korea, the Rural Development Administration (RDA) has recently developed a new variety of licorice, ‘Wongam (Glycyrrhiza glabra × Glycyrrhiza uralensis)’. In this study, the growth, yield, and pharmacological properties of the Wongam variety were investigated in accordance with temperature conditions to evaluate the suitability of the Wongam variety for cultivation. In the temperature gradient tunnel (TGT) atEumseong, Chungbuk, when the temperature was raised to 0°C ‐ 1.5°C higher than the local temperature in 2017, the average height of the Wongam variety was 121.6 cm and the average yield (10a) was 878.1 kg. When the temperature was raised to be 3.0°C ‐ 4.5°C above the local temperature, the average height was 146.5 cm and the average yield (10a) was 1,484.6 kg, anincrease of 69.1%. When the temperature was raised to be 4.5°C ‐ 5.9°C above the local temperature, the average height decreased to 132.5 cm and the yield decreased 8.0% to 1,366.3 kg. Glycyrrhizin content of Wongam roots decreased steadily from 0.98% to 0.87% as the temperature in the TGT increased. The overall average content was 0.91%, which is presumed to be because of a lack of accumulation due to short-term cultivation. The results of this study showed thatthe production of the Wongam variety increased as the temperature was raised to about 4.5°C higher than the local temperature based on the 2017 temperature of Eumseong, Chungbuk, Korea. Therefore, if the current cultivation area formed in
