A new barley (Hordeum Vulgare L.) cultivar ‘Wooho’ was developed by Honam National Agricultural Research Institute (HARI) in 2005. It had good forage characteristics (smooth awn) and showed high forage production in the 5 locations of paddy field. ‘Wooho’ was developed from the cross between SB87125〔Oweol//(SB77011)/SB79124 (Bengei//Hagane/ Bunong) ///Y7213-SD607-CM67-Milyang12〕and SB83024 (1012.2-IB65/Ol//Samheung/Suwon18-Gang) made in 1994. Subsequent selections were made throuhg bulked and pedigree selection methods. SB94104-B-B-B-B-79 was selected for smooth awn and agronomic performance in 2001 and placed in preliminary yield trial. In 2003, it was designated as ‘Suwon 396’ and performed regional yield trials. The average forage yield of ‘Wooho’ were 11.0 MT/ha and 10.9 MT/ha at May 20 and drought stage, respectively. The shattering rate of ‘Wooho’ was lower than that of ‘Ol’. It showed superior forage quality to the check variety when harvest early drought stage. ‘Wooho’ would be recommended as a cultivar of barley for whole crop forage with smooth awn.

This study was done to understand the G x E interaction of rice blast reaction for Japonica high quality rice varieties and to observe blast pattern for high quality varieties. Twenty one percent of the total sum of squares (SST) in blast reaction data of high quality Japonica varieties is attributed to genotype (G) by environment (E) interaction variation. This portion of blast response is higher than 8～12% of G x E effect in blast severity data obtained from various ecotypes of rice varieties. Blast response scores obtained from high quality Japonica varieties group were more severely affected by environment condition than mixed groups with Japonica and Indica varieties. Interaction Principal Component Analysis (IPCA) scores obtained from AMMI analysis for the leaf blast response implied variation of G x E interaction. Correlation analysis suggested that IPCA1 was associated with latitude, maximum mean temperature, precipitation and mean cloud amount. IPCA2 was associated with mean relative humidity, and IPCA3 was associated with precipitation and minimum relative humidity. Pattern analysis generated nine genotype clusters according to blast reaction over 11 regions. Collectively, the A, B, C, and D groups were susceptible to rice blast, where as the E, F, G, H, and I groups were relatively resistant to rice blast through multi-location blast nursery test. Relationship between the identified genes of high quality varieties and blast scores at each test site in the level of group could be analyzed based on the results from G x E Interaction analysis.

The protective effect of ethanol extract of Korean mistletoe (KM; Viscum album coloratum) on hydrogen peroxide (H2O2)-induced neurotoxicity was examined in primary cultured rat cortical neurons. H2O2 reduced viability of cortical neurons in a concentration-dependent manner. The addition of KM, over a concentration range of 10 to 100 μg/ml, concentration-dependently prevented the H2O2(100 μM)-induced neuronal cell death, as assessed by a 3-[4,5-dimethylthiazol-2-yl]-2,5-di-phenyl-tetrazolium bromide (MTT) assay and Hoechst 33342 staining. KM significantly inhibited H2O2-induced elevation of the cytosolic Ca2+ concentration ([Ca2+]c), which was measured by a fluorescent dye, fluo-4 AM. KM inhibited glutamate release into medium and generation of reactive oxygen species (ROS) induced by H2O2. These results suggest that KM may mitigate the H2O2-induced neurotoxiciy by interfering with the increase of [Ca2+]c, and inhibiting glutamate release and generation of ROS in cultured neurons.

“Chohan” (Avena sativa L.), a winter forage oat was released by the Honam Agricultural Research Institute (HARI), NICS, RDA in 2006. “Chohan” was selected from the cross between “Early 80” and “7A 202.210-S”. “Early 80” is a accession from Japan that show
