        7 new sericinjams are in breeding by the hybridization of silkworm genetic resource, that is, ND strain and the parent silkworm, and the feature of new sericinjam was classified by a cocoon color. According to cocoon color, sericinjam showed two kind of color including the light green and yellow. D601, D704 and D707 with the light green silk were a difference to density of color. Also D703, D705, D751 and D752 with the yellow silk showed a difference to density of color. As investigating the pupation rate which means the healthiness of the silkworm, D601 was highest with 93%, and D703 was lowest with 65.6%. The ratio of the sericin silk showed some difference every breed, and D601 among them was highest with 91%. There is close correlation between sericin cocoon quantity and the dried silkgrand weight. The weight of the dried silkgrand for sericinjams which were compared with baeokjam was low about 2.5 ~ 7.9 times. Among sericinjams, D601 was lowest, and D707 was highest. The pure sericin content of sericinjams was an above 96%, and sericin content of per one cocoon was low 1.4 ~ 2.5 times than baeokjam. Blood of silkworm which makes the light green silk exhibited anti bacterial activity against Gram-negative bacteria.

        Barley, ranking fifth among all crops in the world today behind maize, wheat, rice and soybean, has been an important food source in many areas in the world. Moreover having high nutritional value. 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. The objective of this study is to substitute wheat flour with barleys in order to produce new products of white salted noodles and to investigate the effects of substituting flours on quality characteristics of noodles. We investigated the Hunter colour values(lightness, redness, yellowness) of barley noodles. Lightness and yellowness were decreased and redness were increased in barley cooked noodles compare to wheat noodle. As compared to the wheat noodle, barley noodle at 10, 20, 30% substitution ratios had lower hardness, which decreased continuously with substitution levels. Springiness and cohesiveness were also lower than wheat noodles.

        A New six-rowed Naked Barley Cultivar “Nurichal” with good coking quality was developed by cross with HB88154-B-25-1 line and Hinchalssalbory by the Winter Cereal and Forage Crop Research Div. NICS, RDA in 2010. HB15305-B-B-31-2 was selected in 2006 and designated as ‘Iksan 95’. It showed good agronomic performance in the regional yield trials (RYT) from 2008 to 2010 and was released with the name of ‘Nurichal’ possessing good water absorption and expansion. The average heading and maturing dates of ‘Nurichal’ were April 24 and May 30 in paddy field, which were two day and one day later than those of the check cultivar ‘Saechalssalbori’ respectively. The new cultivar, ‘Nurichal’, had 82cm of culm length that was 5cm shorter than that of ‘Saechalssalbori’, and 4.0cm of spike length. It showed 774 spikes per m2, 63 grains per spike, 25.0 g of 1,000-grain weight, and 793 g of test weight. ‘Nurichal’ showed a little weaker winter hardiness than those of the check cultivar, ‘Saechalssalbori’ and showed similar lodging resistance with check cultivar. It sowed stronger resistance to barley yellow mosaic virus (BaYMV) compare to check cultivar. Grain shape was small and round. Protein content was 10.3% and β-glucan content was 6.8%. Its average yield of the pearled grain in the regional yield trial was 3.84 MT/ha in paddy field, which were higher 2% than those of the check cultivar. Its water absorption was similar and expansion was higher than ‘Saechalssalbori’. This cultivar would be suitable for the area above the daily minimum temperature of -6℃ in January in Korean peninsula.

        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.

        In order to get information on tocopherol content and composition in fifty-six soybean germplasms were evaluated by HPLC. From the principle component analysis, the first three components accounted for 71.6% of the total variance of tocopherol content in the germplasms. Principal component 1 showed significant correlations with all the morphological markers except 100-seed weight. Soybean germplasms were divided into three groups by the first two principal components. The highest content of α -tocopherol was 38.6~mug per g in Tanner, while that of ~gamma -tocopherol was 195.6~mug in PI 91073. In case of δ -tocopherol, IT 105622 showed the highest value as 29.8~mug . The contents of tocopherol were gradually increased from the late August to late September, which was 10 days before maturity, in Alchankong and PI 96322. The tocopherol content was higher in seeds from the plants sown early than those sown late. Total tocopherol contents of PI 96188, Geomjeongkong 2, and Suwon 183 grown in Gimje were higher than those grown in Iksan, but the difference was not observed in PI 96322. These results suggest that the contents of tocopherol in soybean were affected not only by the genotypes but also by environment.

        Pearling, an important primary process on food barley utilization, refers to the gradual removal of grain tissues starting from the outer grain tissues/layers, bran, and germ. The removal of barley bran through pearling yields a bright white kernel that is ideal for various food applications. The removed grain layers are usually sold as feed. However, its use for producing various innovative food products such as high-fiber functional pasta. Here we investigated composition of pearled barley. Barley grains from two hull-less varieties, Saechalssal and Hinchalssal, were pearled to various degrees(10-60%). The composition (protein, β-glucan, fat, ash, total phenol and proanthocyanidin) of pearled barley fractions flour(PF) was determined. Protein, fat, ash, total phenol and proanthocyanidin content was decreased in PF according to increasing pearling degree. Hunter L value and whiteness was increased. β-glucan content also was increased from 3.35, 2.73% to 8.9, 9.3% in Sachalssal and Hinchlssal individually. PF of Sachalssal and Hinchalssal showed different content in all components. Protein content was the highest in 90~80% flour fraction. Total phenol, proanthocyanidin and crude fat content was the highest in outer grain layer, bran(100~90% fraction) than other fractions.
