Abstract
"Jangbeol 102" is a new orchardgrass(Dacrylis glomerata L.) variety developed by the National Livestock Research Institute(NLRI) in 2002. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. Agronomic growth characteristics and forage production of "Jangbeol 102" were examined at Suwon from 1995 to 1998, and regional trials were conducted in Suwon, Namwon and Pyungchang from 1999 to 2002 and Jeju from 2000 to 2002, respectively. "Jangbeol 102" showed semi-erect growth habit in fall and spring and medium to long type in length of flag leaf and upper internode. Plant height of "Jangbeol 102" was similar to that of standard variety, "Ambassador" and heading date was I day faster as 11th May compared to Ambassador. Characters such as winter hardiness, regrowth, moisture tolerance, disease resistance of "Jangbeol 102" were stronger or better than those of Ambassador, specially in regrowth and disease resistance. "Jangbeol 102" showed 18% higher dry matter yield(13,430kg/ha) compared to Amabassador. Nutritive value was appeared to be similar in both varieties.assador. Nutritive value was appeared to be similar in both varieties.
