A new F1 hybrid variety, Daekwanhwang, using a male sterile line was developed in Highland Agriculture Research Center (HARC), Rural Development Administration (RDA) at 2007. The cross was made between a male sterile line Manchuhwang as a female parent and NIHA-5001 as a male parent in 2001. It was preliminarily selected as NIHA-GA-1 and advanced field trial was performed in 2003. Regional yield trial was carried out at three different highland areas from 2004 to 2006. The plant growth habit is erect and intermediate in plant shape and maturity, respectively. It grows 74.cm in height and has 8.5 number of leaves each plant. The average bulb weight of Daekwanhwang, was similar to that of commercial F1 hybrid Higuma and bulb shape is oval. The skin color is yellowish brown and the storability is longer than that of Higuma. Soluble solid contents and dry matter were higher than those of commercial F1 hybrid cultivar,Higuma
