'Ggoma' is a new Hibiscus variety released by a mutation breeding using a gamma ray irradiation at the Korea Atomic Energy Research Institute (KAERI). One hundred seeds of the original native variety, 'Hongdansim 2', were collected from around a 35 year old plant, grown in a breeding field in Namyangju, Gyeonggi Province. The seeds were irradiated with a 100 Gy gamma ray from a ∨60Co source at KAERI in 1991 (Fig. 1). The original variety, 'Hongdansim 2' within the I-b category represents a single flower, with an intermediate petal width and a light purple color with a red eye in the center of its flower.
