Abstract

A new grafted cactus cultivar, called 'Hwangseon', Gymnocalycium mihanovichii, is a hybrid crossed between two orange color cultivars 'Geoseong' and 'Huhwang'. Mating was performed in the greenhouse of National Institute of Horticultural & Herbal Science (NIHHS) in 2005. The harvested seeds were sown at 100 mL volumetric flasks filled with 'Kyoto' medium. Seedling had been grafted into a young rootstock, Hylocereus trigonus, and cultured in vitro in 100 mL test tube for more than six months. After re-grafting and planting in the green house in 2006, their characteristics were evaluated three times until 2009. The new cultivar has a flat round shape and bright yellow skin color. In addition, it has 7 to 9 ribs with gray and straight spines on the body and produces an average of 12.3 offsets.
