‘Dahye’, a new covered cultivar derived from the crosses between ‘Suwon318’ and‘Suwon311’ developed at the Honam Agricultural Research Institute (HARI), NICS, RDA in 2007. The initial crossing was made in 1996 and an elite line, ‘SB964008-B-B-B-92’ was selected from under yield trial test in 2004. It was designed as ‘Iksan409’ and showed a high yield and had good quality in the regional yield trials (RYT) from 2005 to 2007. It was released with the name of ‘Dahye’.‘Dahye’had a rate Ⅲ growth habit, green leaf and stem, compact spike and long rough awns. The heading date was April 29 in upland and April 20 in paddy field, which was 2 and 5 days earlier than that of check cultivar,‘Olbori’, respectively. It had 88 cm of culm length, 4.2 cm of spike length and 666 spikes per m2, 52 grains per spike, 35.6 g of 1,000-grain weight and 702 g of test weight. It showed stronger winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those of check cultivar. It had similar protein content with check cultivar and higher whiteness and diastatic power (DP) than those of Olbori. The average yield of the pearled grain in the regional yield trial (RYT) was 4.00 ton ha-1 in upland and 4.11 ton ha-1 in paddy field. This cultivar would be suitable for the area that the daily minimum mean temperature is above -8℃ in January in Korean peninsula.
