The sorghum (Sorghum bicolor (L.) Moench) variety 'Sodamchal' was developed and registered by Department of Sothern Area Crop Science, National Institute of Crop Science (NICS) in 2013. This variety was developed from the cross between 'Hwanggeumchal' with brown grain and 'Jungmo4001' with semi-dwarf trait. 'Sodamchal' is the first semi-dwarf stature with waxy endosperm ever developed in Korea. The yield performance of 'Sodamchal' was 2.95 MT/ha in local adaptability test for 2 years. It had 91 cm culm length, which was 58 cm shorter than that of 'Hwanggeumchal', 26.3 cm panicle length, 22.0 mm thickness of culm, 21.1 g in 1,000 grain weight. It could be reduce the lodging problem and also adapted to mechanized cultivation. 'Sodamchal' produces high quantities of polyphenol and radical scavenging activitiy with diphenyl-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) in pigmented testa. Above all 'Sodamchal' is suitable for use as a parental source for the development of improved pollinator parent lines for developing semi-dwarf sorghum with waxy endosperm and antioxidant activity.
