호위축병저항성 다수성 맥주보리 오름

A New High-Yielding Malting Barley Cultivar Oreum with High Yielding and BaYMV Resistance

오름 은 맥주보리 고품질 내재해성 신품종을 개발하기 위하여 1997년에 작물과학원 에서 보리 호위축병 저항성인 Kinuyudaka 를 모본으로 하고 단간이며 내도복성인 삼도보리 를 부본으로 인공교배하여 육성한 품종으로, 2006년 12월에 농촌진흥청 농작물 직무육성 신품종 선정 위원회에서 오름 이라 명명하여 국가품종목록에 신품종으로 등록하였으며 그 특성은 다음과 같았다.

A new malting barley variety, Oreum , was developed from the a cross between Kinuyutaka and Samdobori at the Honam Agricultural Research Institute (HARI) in 2006. An elite line, YMB2077-2B-24-1-2, was selected in 2003 and designated as Milyang132 . It showed good agronomic performance in the regional adaptation yield trials (RYT) from 2004 to 2006, and was released with the name of Oreum having high yielding and BaYMV resistance. The average heading and maturing dates of Oreum were April 18 and May 24, which were 2 days later than Jinyang , a leading variety, at RYT. Oreum had longer culm length (75 cm), more spikes per m^2 (990), and lighter 1,000 grain weight (35.2 g) than those of Jinyang in paddy field conditions. It was showed resistance to BaYMV at the regions of Naju, Jinju and Milyang but moderate resistance at Iksan. However, the response to other environmental stresses of was similar to Jinyang The yield potential of Oreum was about 5.43 MT/ha, 4.93 MT/ha in upland and paddy fields which was about 80%, 35% higher than Jinyang in the regional adaptation yield trials (RYT), respectively. It has good malting quality including high grain assortment, germination capacity ratio, water sensitivity and high the malt production and the extract and short filtration speed than those of Jinyang .
