'Lucky one' 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 develope this new variety of orchardgrass. The agronomic growth characteristics and forage productivity of 'Lucky one' were examined at Cheonan from 2010 to 2011. Regional adaption trials were conducted in Cheonan, Hoengseong, Jinju, and Jeju from 2012 to 2014. 'Lucky one' showed growth habit of medium type in fall and spring. It has short flag leaf length with long upper internode. Plant height of 'Lucky one' was 3 cm more than that of control variety, 'Amba'. Its heading date was 2 days later than that of control variety ‘Amba’. Characteristics such as waterlogging and disease resistance of ‘Lucky one’ were stronger or better than those of control variety, 'Amba', Especially, dry matter yield of 'Lucky one' (16,191 kg/ha) was increased 38% compared to that of control variety, 'Amba'(11,778 kg/ha). Nutritive feed values of 'Lucky one' appeared to be similar to those of control variety 'Amba' except in Vitro dry matter digestibility (IVDMD) and crude protein content.
