초록

‘Luckyone 2ho’ is a new orchardgrass (Dactylis glomerata L.) cultivar developed by the National Institue of Animal Science (NIAS) in 2017. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. The agronomic growth characteristics and forage productivity of ‘Luckyone 2ho’ were examined at Cheonan from 2012 to 2014, and regional trials were conducted in Cheonan, Pheonchang, Jinju and Jeju from 2015 to 2017, respectively. ‘Luckyone 2ho’ showed medium type growth habit in fall, and medium in length of flag leaf and very long upper internode. Plant height of ‘Luckyone 2ho’ was 3 cm less than that of standard cultivar, ‘Potomac’ and heading date was 1 days later than 5th May compared to standard cultivar, ‘Potomac’. Characteristics such as waterlogging and disease resistance of ‘Luckyone 2ho’ were stronger or better than those of standard cultivar, ‘Potomac’, Especially, dry matter yield of ‘Luckyone 2ho’(15,980 kg/ha) increased 9 % compared to that of standard cultivar, ‘Potomac’(14,702 kg/ha). Nutritive values were appeared to be similar in both varieties except in Vitro dry matter digestibility(IVDMD) and crude protein and total digestible nutrients (TDN).
