‘Johyun’ was a new adlay variety which was developed from three way crosses of (Suwon-6xOkayama)x UCN300-25 at the Northern Agricultural Research Station, Gyeonggi Province ARES. This variety had purple sheath and green leaf blade in primitive growth stage and green leaf and culm in heading stage. Colors of pistil and seed coat were milky-white and dark-brown, respectively. Plant height of Johyun was 179 cm and shortened 22 cm less than Yulmoo-1 which was tested by check variety. Johyun shortened 8 days of heading date and 15 days of ripening date compared with Yulmoo-1. Yield of Johyun was 320 kg/10a of hulled grains in three regional yield trials and 18% higher than Yulmoo-1. This variety was adaptable to single cropping in central and northern region of Korea.
