 Abstract
`Onnuri 2ho` is a new orchardgrass (Dactylis glomerata L.) variety developed by the National Institute of Animal Science (NIAS) in 2014. Four superior clones were selected and polycrossed for seed production to develop this new variety of orchardgrass. The agronomic growth characteristics and forage productivity of `Onnuri 2ho` were examined at Cheonan from 2010 to 2011. Regional adaptation trials were conducted in Cheonan, Hoengseong, Jinju and Jeju from 2012 to 2014. `Onnuri 2ho` showed growth habit of medium type in fall and spring. It is long in length of flag leaf with medium upper internode. Plant height of `Onnuri 2ho` was 4 cm more than that of control variety, `Amba`. Its heading date was 4 days later than compared to control variety, `Amba`. Characteristics such as waterlogging and disease resistance of `Onnuri 2ho` were stronger or better than those of control variety, `Amba`, Especially, the dry matter yield of `Onnuri 2ho` (15,814 kg/ha) was increased 34 % compared to that of control variety, Amba (11,778 kg/ha). Nutritive feed values of `Onnuri 2ho` appeared to be similar to that of control variety `Amba` except in Vitro dry matter digestibility (IVDMD).
