A new anthocyanin-rich hybrid variety, 'Saekso 1', is developed which is characterized by yellow grains, and purple husks and cobs. This variety was produced by crossing two inbred lines, 'HA1' (as the seed parent) and 'HA2' (as the pollen parent). It was made in 2008/2009 and evaluated in Hongcheon for two years. After evaluation, the selected variety was named 'Saekso 1' and was approved for a variety registration in 2014. The anthocyanin content of 'Saekso 1' in husk was 10.39±0.09 g/100 g, which was much higher than that of Kangilok (0 mg/100 g). Since regional tests were conducted only in Gangwon province, this variety is recommended only in that region for commercial cultivation. 'Saekso 1' is a health food resource for bioactive materials (Registration No. 4967).
