“Onnuri” is a new orchardgrass(Dactylis glomerata L.) variety developed by the National Institue of Animal Science (NIAS) in 2011. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. Agronomic growth characteristics and forage production of “Onnuri” were examined at Cheonan from 2009 to 2011, and regional trials were conducted in Cheonan, Pyungchang Jinzu 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 more than 10cm that of standard variety, “Amba” and heading date was 5 days earlyer than 16th May compared to Amba. Characteristics such as waterlogging, disease resistance of “Onnuri” were stronger or better than those of Amba, specially “Onnuri” showed 18% higher dry matter yield (14,775kg/ha) compared to Amaba(12,523kg/ha). Nutritive value was appeared to be similar in both varieties.
