‘Taegang’ is a new six-rowed covered barley cultivar developed by the National Institute of Crop Science (NICS), R.D.A. This cultivar is developed from a cross between ‘Suwon287’ and ‘Olbori’ in 1992. An F8 selection was made at NCES in 2000 and it was te

A new sprout-soybean cultivar, “Wonhwang” was developed at the Honam Agricultural Research Institute (HARI) in 2005. Wonhwang was selected from a cross between Camp and Myeongjunamulkong. The preliminary, advanced, and regional yield trials for evaluation and selection of Iksan45 were carried out from 2001 to 2005. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, grayish brow hilum, lanceolate leaflet shape and small seed size (10.0 grams per 100 seeds). The maturity date of Wonhwang is 7 days earlier than that of the check variety, Pungsan. It has good seed quality for soybean-sprout, and resistance to lodging. It has also been identified to have resistance to soybean mosaic virus (SMV) and necrotic symptom(SMV-N). The average yield of “Wonhwang” was 2.80MT/ha, which was higher by 4% than “Pungsannamulkong” at the regional yield trials.

A new soy sauce and soy paste soybean cultivar, “Hojang” was developed from the cross between HS12 (Jangyeobkong/Hwangkeumkong) and Suwon153 by the soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The prel

A new sprout-soybean variety, “Dagi” was developed from the cross between Namhaekong and D70-6545 by the soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The preliminary, advanced, and regional yield trial

A new soybean variety, “Sunam” was developed from the cross between Kosuzu and Bukwangkong by soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The preliminary, advanced, and regional yield trials for evalu

Rice (Oryza sativa L.) plants were cultivated to examine changes in antioxidative defence mechanism induced by elevated ozone levels. Catalase activities in tolerant Jinpumbyeo and susceptible Chucheongbyeo under ozone fumigation were reduced at 5 hrs and 3 hrs after ozone fumigation, respectively. With the increased ozone supply, peroxidase activity in Jinpumbyeo was steadily enhanced whereas in Chucheongbyeo it was not changed. Four SOD-isozymes were detected by NBT staining of native-PAGE. Two isozymes of them were obviously induced by ozone supply, particularly in Jinpumbyeo. The continuous ozone fumigation increased remarkably putrescine levels in leaves whereas it did not affect the levels of spermidine and spermine. In this study, it was implied that ozone in cell inhibits strongly diamine oxidase and thus promotes ethylene biosynthesis which will cause the senescence in rice plants.

Genetic diversity and soybean sprout-related traits were evaluated in a total of 72 soybean accessions (60 Glycine max, 7 Glycine soja, and 5 Glycine gracilis). 100-seed weight (SW) was greatly varied and ranged from 3.2g to 32.3g in 72 soybean accessions. Positive correlation was observed between GR and hypocotyl length (HL), whereas negative correlation was observed between SW and hypocotyl diameter (HD). Re-evaluation by discarding two soybean genotypes characterized with low GR indicated that much higher correlation of sprout yield (SY) with HD and SW. Based on the principal component analysis (PCA) for sprout-related traits, 57 accessions were classified. Soybean genotypes with better traits for sprout, such as small size of seeds and high SY, were characterized with high PCA 1 and PCA 2 values. The seed size in second is small but showed low GR and SY, whereas the third has large seed, high GR and more than 400% SY. In genetic similarity analysis using 60 SSR marker genotyping, 72 accessions were classified into three major and several minor groups. Nine of twelve accessions that were identified as the representatives of soybean for sprout based on PCA were in a group by the SSR marker analysis, indicating the SSR marker selection of parental genotypes for soybean sprout improvement program.

A single cross hybrid, 'Heugjeomchal', is a white and black bicolor waxy corn (Zea mays L.) developed by the Maize Experiment Station (MES), Gangwondo Agricultural Research and Extension Services (GARES) in Hongcheon in 2000. 'Heugjeomchal' was made by cr
