A new grafted cactus variety, 'Dahong', Gymnocalycium mihanovichii, is hybrid crossed between '9508021' line with red and black color, and 'Jinhong', with dark red color in 2002. It was cultivated for 6 months after grafted in vitro and planted at 100 mL test tube. After grafting in vivo in 2003, the various characteristics of this was evaluated three times until 2006. It has the flat-round shape and dark red skin, and produces the daughter globes at areoles, which are arranged well at the low part of globe. In addition, it has 8~10 ribs and the gray and slant spines in body. The ability of propagation is better than 'Jinhong' to produce approximately 13.6 daughter globes.

A new grafted cactus cultivar, G. 'Gohong', was developed by crossing 'DR' line with dark red color and G. 'Seolhong' with dark red color in 2004. It grew for 6 months after grafting in vitro and culturing at 100 mL test tube. After grafting and planting in greenhouse in 2005, various characteristics were evaluated three times until 2008. It has flat-round shape and dark red skin. In addition, it has 8 to 10 ribs and gray and straight spines on the body. The diameter of it was 44.1 mm after 10 months. It grew bigger and faster comparing with G 'Seolhong' cultivar. The ability of propagation in G. 'Gohong' is similar to that of G. 'Seolhong' producing approximately 12.1 daughter globes for 10 months after planting.

A new grafted cactus cultivar, G. mihanovichii 'Hwangun', for exporting abroad, was developed by crossing G. mihanovichii 'Hwangwol' variety with yellow and orange color, and G. mihanovichii '0111021' line with yellow color in 2008. It grew for 6 months after grafting in vitro and culturing at 100 mL test tube. After grafting and planting in greenhouse in 2005, various characteristics were evaluated three times until 2008. It has flat-round shape and bright yellow skin. In addition, it has 7 to 9 ribs and brown straight spines on the body. The diameter of it was 40.9 mm after 10 months after planting, and small comparing with G. mihanovichii 'Hukwang' cultivar. The ability of propagation in G. mihanovichii 'Hwangun' is prior to that of G. mihanovichii 'Hukwang' producing approximately 22.3 daughter globes for 10 months.
