‘Heukharang’ is a pure line variety selected from native seeds; this lettuce variety has stronger leaves and longer foliar than traditional red skirt varieties. From 2011 to 2015, productivity was tested by collection and pure line selection. The new breed, ‘Heukharang’, was found to be narrow and black oval with anthocyanin pigments evenly spread over the leaves. ‘Heukharang’ had a stronger bitter taste than the Red Skirt variety, since its lactucin content was >100 times higher. This cultivar also showed a much higher content of chlorogenic acid and tocopherol. This new variety ‘Heukharang’ can thus be recommended as a variety that can fully utilize functional ingredients in lettuce, since it is close to the existing variety of red skirt lettuce and has more functional ingredients (Registration No. 7569).
