Abstract

A new malting barley variety, Hopum, was developed from the cross between Sacheon 6 and Misato Golden at thenated as Milyang114. It showed good agronomic performance in the regional adaptation yield trials (RYT) from 2001 to 2003 andwas released with the name of Hopum having BaYMV resistance. The average heading and maturing dates of Hopum were April15 and May 21, which were same and 2 days earler than Jinyang, respectively, at the regional adaptation yield trials (RYT).Hopum had longer culm length (84 cm), more spikes per m2paddy field condition. It showed resistance to BaYMV in regions of Naju, Jinju, Milyang and moderately resistance in Iksan. How-ever, the response mode of Hopum to other environmental stresses was similar to Jinyang. The yield potential of Hopum in theregional adaptation yield trials (RYT) was about 5.28 MT/ha in paddy fields, which was about 20% higher than Jinyang. While inincluding high grain assortment, low protein content, and germination energy, high malt extract and friability and short filtrationspeed. The Kolbach index and diastatic power of Hopum were better than those of Jinyang.
