Onnuri is a new orchardgrass (Dactylis glomerata L.) cultivar developed by the National Institute of Animal Science (NIAS) in 2011. To develop the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. The agronomic growth characteristics and forage productivity of Onnuri were examined at Cheonan from 2009 to 2011, and regional trials were conducted in Cheonan, Pyeongchang, Jinju and Jeju from 2009 to 2011, respectively. Onnuri showed medium type growth habit in fall and spring, and medium in length of flag leaf and long upper internode. Plant height of Onnuri was 5cm more than that of the standard cultivar, Amba and the heading date was 5 days earlier than that of Amba (16th May). Characteristics, such as waterlogging and disease resistance, of Onnuri were stronger or better than those of Amba, Especially, dry matter yield of Onnuri (14,775 kg/ha) increased by 18% compared to that of Amba (12,523 kg/ha). Nutritive values appeared to be similar in both varieties.
