A new graft cactus (Gymnocalycium mihanovichii) cultivar “Hwiseong” was developed from a cross between G. mihanovichii “Orenge” and a line “943011” by in vitro grafting and line selection at National Horticultural Research Institute, Rural Development Administration in 1999. The trials for investigation of characteristics were carried out three times from 2001 to 2003. The color of body and tubercles was a mix of orange and yellow. Flat round globe had 8 to 9 ribs with medium depth. Spine was straight and soft with light gray. Growth was medium vigorous as reach 40 mm in diameter in ten month after planting. Plant tissue was strong. Propagation ability was excellent as set as many as 14.5 tubercles. Characteristics of the cultivar could be maintained by vegetative propagation, and growers should pay attention to protection from strong sun light and virus infection. The cultivar was applied for a variety protection and was released to commercial growers in 2004.
