‘Dian’ was developed by crossing ‘Milyang85/Suwon335’, which has tolerance to lodging and high yield, and ‘Milyang122’, which has good brewing qualities, in 2003. The regional yield trials were conducted for ‘Dian’ as a breeding line ‘Iksan168’ in four different regions of Korea from 2012 to 2014. The heading and maturing dates of ‘Dian’ in paddy and upland fields were similar to ‘Hopum’. ‘Dian’ had a shorter culm length than ‘Hopum’ in paddy and upland fields, showing tolerance to lodging stress. The yield potential of ‘Dian’ was approximately 18% higher than that of ‘Hopum’ in the paddy fields, but there were no significant differences in the upland fields. ‘Dian’ had rym1 and rym5 genes and showed resistance to barley yellow mosaic virus (BaYMV), but was susceptible to powdery mildew. It also had good quality for brewing and was similar to ‘Hopum’. ‘Dian’ had a higher assortment ratio (94%) than ‘Hopum’ (89%). Regarding grain quality, ‘Dian’ was similar to ‘Hopum’ in protein content, β-glucan content, and husk rate. Concerning malt quality, ‘Dian’ showed a 71.6% extraction rate, 3.6% soluble protein content, and 33.0% Kolbach index, which are similar to the values of ‘Hopum’. Other malt qualities of ‘Dian’ include 185 WK (Windisch-Kolbach) diastatic power and 81.4% friability, which were lower than those of ‘Hopum’. Therefore, ‘Dian’ with high yield, tolerance to lodging, and resistance to BaYMV is considered to be stable for cultivation (Registration No. 8241).

A malting barley variety, ‘Nurimaeg’, was developed with resistance to barley yellow mosaic virus (BaYMV), tolerance to lodging stress, and good brewing quality. ‘Nurimaeg’ was developed by crossing Milyang127 and Miharu gold in 2004. Regional yield trials were conducted for ‘Nurimaeg’ as a breeding line ‘Iksan175’ in four different regions from 2014-2016. It has a type I growth habit, and its average heading and maturity dates were April 12 and May 20, respectively-which were 1 day later than the maturity date of ‘Hopum’ variety. As ‘Nurimaeg’ has a shorter culm length (77 cm) than that of ‘Hopum’, it showed tolerance to lodging stress. This variety possesses the rym5 gene and is resistant to BaYMV. It showed a 42.9 g 1000-grain weight and 90% assortment ratio. The yield potential of ‘Nurimaeg’ was 408 kg/10a, which is approximately 18% higher than that of ‘Hopum’. Analysis of grain quality for malting showed that ‘Nurimaeg’ has high quality of low protein and β-glucan content. Malt quality analysis revealed that it has 72.8% extract, 4.2% soluble protein, 38.9% kolbach index, and 243 WK diastatic power, which all were similar to those of ‘Hopum’. ‘Nurimaeg’ would be suitable for cultivation in the areas of Korea that have a daily minimum temperature of -4℃ in the month of January (Registration No. 7960).
