Current consumers have interest in nutrition and health. So, the interest in barley for other food and industrial applications is increasing. Noodles, which have been consumed largely in korea, are usually made from wheat flour, salt and appropriate amount of water. A New Six-rowed Naked Barley Cultivar “Dahan” was developed in 2012, have high winter hardness, lodging tolerance and good noodle property. It was crossed in 2001, and an elit line was selected in 2010 and designated as ‘Iksan 106’. It showed good agronomic performance in the regional yield trials (RYT) from 2010 to 2012. The average heading and maturing dates of “Dahan” were April 29 and June 3 in paddy field, which were two day earlier than those of the check cultivar ‘Saessalbori’ respectively. The new cultivar, “Dahan”, had 92cm of culm length and 3.9cm of spike length. It showed 625 spikes per m2, 54 grains per spike, 31.3 g of 1,000-grain weight, and 815 g of test weight. “Dahan” showed better resistance to BaYMV (Barley yellow mosaic virus) than those of the check cultivar. Its average yield of the pearled grain in the regional yield trial was 4.32 MT/ha in paddy field, which were 16% higher than those of the check cultivar. It showed higher breakdown and setback than those of the check cultivar. Texture properties of noodle was better in hardness, adhesiveness, chewiness. This cultivar would be suitable for the industrial application as noodle and bread.

A New Six-rowed Naked Barley Cultivar “Ganghocheong” with High anthocyanin content and green aleurone the cross between Iri26 and Sagukgwa67 by the National Institute of Crop Science, RDA in 2009. An elite line HB14190-B-61-3-2-3-3-5-1 was selected in 2004 and designated as ‘Iksan 92’. It showed good agronomic performance in the regional yield trials (RYT) from 2007 to 2009 and was released with the name of “Ganghocheong” possessing high anthocyanin content and green lemma non-waxy endosperm. The average heading and maturing dates of “Ganghocheong” were April 20 and May 29 in paddy field, which were two days earlier and same than those of the check cultivar ‘Saessalbori’ respectively. The new cultivar, “Ganghocheong”, had 81cm of culm length and 6.0cm of spike length. It showed 702 spikes per m2, 60 grains per spike, 30.0 g of 1,000-grain weight, and 794 g of test weight. “Ganghocheong” showed better resistance to BaYMV (Barley yellow mosaic virus) than those of the check cultivar, ‘Saessalbori’. Its average yield of the pearled grain in the regional yield trial was 4.02 MT/ha in paddy field, which were 1% lower than that of the check cultivar, respectively. Anthocyanin content was 122.1㎍/g that was higher 2 times than that of zasoojeongchalssalbori. This cultivar would be suitable for the area above the daily minimum temperature of -6℃ in January in Korean peninsula.

Barley (Hordeum vulgare L.) and barley byproduct, waxy and non waxy genetic type, were prepared and investigated for its biological activity. The total phenolic contents, tyrosinase and xanthin oxidase inhibition activity of the barley extracts were measured and compared with those of a barley byproducts extracts powder. The contents of total phenolic compounds of the barley byproducts, waxy and non waxy type, were 18.60 and 17.92 mg/g of sample, respectively. Inhibition rates (%) of the mushroom tyrosinase of the waxy type barley and barley byproducts extracts powder were 16.30 and 33.60% at 250 ppm, respectively. Tyrosinase inhibition activity of barley byproduct extracts regardless of waxy and non waxy type showed higher than that of arbutin (5%). The samples showed an inhibition effect of xanthin oxidase. At 2,500 ppm of sample concentration, the inhibition effect of xanthine oxidase of waxy type barley (WB), non waxy type barley (NB), waxy type barley byproducts (WBP), and non waxy type barley byproducts (NBP) was 9.92, 16.06, 14.11, and 13.86%, respectively.

국내 시판 보리쌀 107개 제품을 수집하여 단백질, -glucan 함량, 백도, 찰성비율, 취반특성 및 호화특성 등을 분석하였으며 그 결과는 다음과 같다. 국내 유통 메성보리 쌀의 단백질 함량은 6.62~11.38%였고, -glucan 함량은 2.44~6.95%, 백도는 29.0~44.4이었으며 흡수성은 135~284%, 퍼짐성은 227~457%이었다. 찰성보리쌀의 경우 단백질은 7.17~12.57%, 백도는 27.1~49.6, -glucan 함

Almost of Korean has used the barley mixing with rice and there are many barley brands have been sold in Korea. In this study, we investigated protein, -glucan content, waxy β ratio, cooking property and whiteness of 107 Korean barley products. The protein, β-glucan content and whiteness of waxy barley(7.17-12.57%, 2.81-7.38%, 27.1-49.6) were higher than non-waxy barley products(6.62-11.38%, 2.44-6.95%, 29.0-44.4). Waxy barley had a better cooking properties than non-waxy barley products. Water absorption and expansion of waxy barley(218-593%, 366-593%) were higher than non-waxy barley(135-284%, 227-457%). These properties and components were significantly different with producing area. Protein showed positive correlation with β-glucan in non-waxy and waxy barley(r=0.632***, r=0.453**). Whiteness showed negative correlation with protein content in non-waxy barley and waxy barley(r=-0.433***, r=-0.343**). Waxy ratio of 49 waxy barley brands was ranged from 84.4% to 100%. Average was 96.7%.
