A new Rehmannia glutinosa cultivar ‘Tokang’ was derived from ‘Jihwang 1’ seedlings by medicinal crop breeding team of National Institute of Horticulture and Herbal Science, RDA in 2009. It has pink flower, dark brown seed coat, light yellow root cortex. The plant type was some rising from the ground. The content of catalpol and extract were higher than the ‘Jihwang 1’(check variety). The content of catalpol was 4.55% and the extract was 71.2%. It showed stronger resistance to root rot compare with the ‘Jihwang 1’. The regional yield trials were conducted at three different locations from 2007 to 2009. The average yield of ‘Tokang’ was 21.1ton/ha, which was 12% more than the ‘Jihwang 1’. This cultivar is adaptable to the whole of Korea except for mountain areas. (Registration No. 4725)
