The physicochemical properties and cooking quality of Saechalssal bori (25% pearled ratio), which is a naked waxy barley, were investigated. The amylose, insoluble dietary fiber (IDF), soluble dietary fiber (SDF), total dietary fiber (TDF), and ${\beta}$-glucan contents of Saechalssal bori were 5.2, 10.8, 9.5, 20.3, and 3.7%, respectively. Pasting temperature, peak and final viscosity, and setback of Saechalssal bori were $66.5^{\circ}C$, 383.2, 231.3, and 55.6 RVU, respectively. The water absorption, expansibility, and soluble solid of Saechalssal bori were 232.2, 405.3, and 3.5%, respectively. As the ratio of water to grain increased, L value increased, whereas a and b values were decreased. The sensory evaluation showed that wateriness and overall acceptability increased with increasing ratio of water to grain, resulting in determining 2.1 times as the optimum ratio of water to grain. The cooked Saechalssal bori prepared using optimum condition had hardness (1.2 kg), cohesiveness (4.0), springiness (1.0), gumminess (5.1), chewiness (5.3), adhesiveness (0.2 kg), and A/H (0.8), respectively.

"Nulichal" was developed by the National Institute of Crop Science, RDA, in 2010. The initial cross was conducted in 2000, and an elite line (HB15305-B-B-31-2) was selected in 2005. Subsequently, preliminary yield and advanced yield trials have designated it as "Iksan 95." It showed good agronomic performance in regional yield trials from 2008 to 2010 and was released as "Nulichal," with resistance against the barley yellow mosaic virus (BaYMV) and high yields with a waxy endosperm. The average heading and maturation dates of "Nulichal" were April 24 and May 30, respectively in paddy fields, which were 1 day later than those of the check cultivar "Saechalssalbori." It had culm and spike lengths of 82 and 4.0 cm, respectively. It showed $774spikes/m^2$, 63 grains/spike, 25.0 g of 1,000-grain weight, and 793 g of test weight. "Nulichal" showed higher levels of resistance to BaYMV than the naturally occurring Iksan (type III strain), Naju (type I), and Jinju (type II). The expansion rate was higher than that of "Saechalssalbori" and its hardness, gumminess, and chewiness were lower than those of "Saechalssalbori." Its average pearled grain yield in the regional yield trial was 4.00 MT/ha in paddy fields, which was 10% higher than that of the check cultivar. The combined availability of "Nulichal" was improved by its increased culm length compared with that of "Hinchalssal."

Hot-water extract from selected medicinal herbs of diabetes prescription was mixed with brown rice and pearled barley flours and extruded to prepare a reconstituted grain for diabetes millitus patients. Even though the cooked reconstituted grain containing medicinal herb extract was somewhat different from cooked ordinary rice in textural properties measured by texture analyzer, it was estimated to be organoleptically acceptable in sensory parameters. The reconstituted grain added with medicinal herb extract reduced the rate of dialysis of glucose evaluated by in vitro dialysis experiment. The effects of reconstituted grain diet on blood glucose levels in diabetes patients were studied during 3-week period. Compared to normal diet, the reconstituted grain diet for 2 weeks significantly decreased the fasting and 2-hr postprandial blood glucose levels in diabetes patients by 14% and 10%, respectively. These results suggested that the reconstituted grain could be used as an effective therapeutic diet for the control of diabetes mellitus.

A new six-rowed naked barley cultivar "Jinjuchal" with high whiteness after cooking and high $\beta$-glucan content was developed from the cross between 'Jinmichapssalbori' with high winter hardiness, lodging tolerance, grain whiteness and pearling yield, and 'Suwon 333' with waxy endosperm by the Honam Agricultural Research Institute (HARI), NICS, RDA in 2007. An elite line, SB962002G-B-B-B-84-4 was selected in 2002 and designated as 'Iksan 79' It showed good agronomic performance in the regional yield trials (RYT) from 2005 to 2007 and was released with the name of "Jinjuchal" possessing high whiteness and low proanthocyanidin waxy endosperm. The average heading and maturing dates of "Jinjuchal" were April 27 and June 1 in paddy field, which were same and one day later than those of the check cultivar 'Saechalssalbori' respectively. The new cultivar, "Jinjuchal" had 81 cm of culm length that was 1cm longer than that of 'Saechalssalbori' and 4.9 cm of spike length. It showed 673 spikes per $m^2$, 56 grains per spike, 27.0 g of 1,000-grain weight, and 752 g of test weight. "Jinjuchal" showed stronger hardiness and better resistance to powdery mildew and BaYMV (Barley yellow mosaic virus) than those of the check cultivar, 'Saechalssalbori' It showed higher $\beta$-glucan content(8.4%) and water absorption rate than those of the check cultivar, 'Saechalssalbori' Its average yield of the pearled grain in the regional yield trial was 3.79 MT/ha in upland, and 3.73 MT/ha in paddy field, which were 1% lower and 3% higher than those of the check cultivar, respectively. Total phenol and proanthocyanidin contents were 4.2 and 0.2 mg/g, respectively. This cultivar is suitable for the area of the daily minimum temperature above $-6^{\circ}C$ in January in Korean peninsula.

"Hyedang", a new covered cultivar derived from the crosses between "Suwon300" and "Haganemugi//CI08397/Haganemugi" developed at the Honam Agricultural Research Institute (HARI), NICS, RDA in 2007. The origin of "Hyedang" is "Iksan 407" (SB951033-B-B-B-72). The initial cross was made in 1995 and the selected line showed a high yield and good quality characteristics under yield trial test in 2004. "Iksan407" consistently performed well for three years (2005-2007) from the four locations of regional yield trial (RYT) in Korea and released as "Hyedang". The characteristics of "Hyedang" were the following: rate III growth habit, green leaf and stem, compact spike and with long rough awns. The heading date was April 25 in upland and April 17 in paddy field, which was 2 and 3 days earlier than that of check cultivar, "Olbori". The culm length was 80 cm which was 8 cm shorter than those of check cultivar. It showed spike length of 4.3 cm and 696 spikes per $m^2$, 51 grains per spike, 35.0 g of 1,000 grain weight and 704 g of test weight. It showed stronger winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those with check cultivar. It showed similar protein content and higher whiteness than those of the check cultivar and diastatic power was higher than that of Olbori. The average yield of the pearled grain in the RYT was $4.17ton\;ha^{-1}$ in upland and $4.27ton\;ha^{-1}$ in paddy field, which was 23% and 9% higher than that of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum mean temperature of $-8^{\circ}C$ in January in Korean peninsula.
