“Dami”is a new japonica rice variety developed and registered by the rice breeding “Jeokjoong”, a white winter wheat (Triticum aestivum L.) variety was developed from the cross “Keumkang”/ “Tapdong”. “Jeokjoong” is an awned, semi-dwarf and soft white winter wheat, similar to “Keumkang” (check variety). The heading and maturing date of “Jeokjoong” were similar to “Keumkang”. Culm and spike length of “Jeokjoong” were 78 cm and 7.5 cm, similar to “Keumkang”. “Jeokjoong” had lower test weight (800 g) and lower 1,000-grain weight (40.1 g) than “Keumkang” (811 g and 44.0 g, respectively). It had resistance to winter hardiness, wet-soil tolerance and lodging tolerance. “Jeokjoong” showed moderate to scab in test of specific character although “Keumkang” is susceptible to scab. “Jeokjoong” had lower flour yield (69.2%) and ash content (0.36%) than “Keumkang” (72.0% and 0.41%, respectively) and similar flour color to “Keumkang”. It showed lower protein content (8.9%) and SDS-sedimentation volume (36.8 ml) and shorter mixograph mixing time (3.5 min) than “Keumkang” (11.0%, 59.7 ml and 4.5 min, respectively). Amylose content and pasting properties of “Jeokjoong” were similar to “Keumkang”. “Jeokjoong” had softer and more elastic texture of cooked noodles than “Keumkang”. Average yield of “Jeokjoong” in the regional adaptation yield trial was 6.19 MT ha-1 in upland and 5.33 MT/ha in paddy field, which was 19% and 16% higher than those of “Keumkang” (5.21 MT/ha and 4.58 MT/ha, respectively). “Jeokjoong” would be suitable for the area above the daily minimum temperature of -10℃ in January in Korean peninsula.team of Honam Agricultural Research Institute, NICS, RDA in 2006. This variety was derived from a cross between Iksan438 with lodging tolerance and high yield potential, and Iksan426 This variety has about 122 days of growth duration from transplanting to harvesting in Honam and Youngnam plain of Korea. It is about 83 cm in culm length and tolerance to lodging. In reaction to biotic stresses, it shows moderately resistance to blast, and resistance to bacterial blight pathogen races from K1 to K3, but susceptible to other major diseases and insect pests. The milled rice of “ami”has high Quality, midium short grain. The milled rice yield of this variety is about 5.92 MT/ha in local adaptability test for three years. “ami”would be adaptable to Middle plain, Honam plain and Youngnam plain area of Korea.

Gwangyang Bay is often severely confronted by photochemical pollutants due to its location and dense emissions. It is located in a basin on the south coast of the Korean peninsula and is crossed by a remarkable cluster of hills and mountains of a small horizontal scale that forms a channel. Clearly, the air flow field has a great influence on the dispersion of air pollutants. The characteristics of the wind flow patterns have an important effect on the dispersion of pollutants emitted. In these situations, the distribution of the ozone concentration is extremely complicated because of the superposition of circulations of the air flow fields, especially in complex coastal region. In this study, we examined the distribution of the high level ozone on Gwangyang Bay particularly during the episode day (for 5 years). Among these days, A high level ozone was induced by the development of a sea/land breeze local circulation system, as well as by an anabatic/catabatic flow from the mountains and valley with weakening of the synoptic wind. High level ozone distribution pattern(6 types) on Gwangyang bay is analyzed and the comparison of each pattern reveals substantial localized differences in intensity and distribution of ozone concentration from the site coherence and UPA analysis of ozone concentration. The observed VOC concentration had much difference in concentrations and daily variations between Jungdong and Samil.

This cultivar has a short grain shape and about 111 days growth duration from transplanting to harvesting in Korean climate condition. This cultivar shows high resistant reaction to the blast, but susceptible to bacterial blight and strip virus. This variety has cold tolerance, compared to Odaebyeo. The milled kernels of ‘'Sinunbong 1’' are translucent with non-glutinous endosperm. It has about 19.2% of amylose content and better palatability of cooked rice compared with ‘'Odaebyeo’'. The milled rice yield of ‘'Sinunbong 1’' is about 5.46 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. ‘'Sinunbong 1’' would be adaptable to the northern plain, mid-mountainous, southern mountainous of Korea.

Blast resistance of 18 rice cultivars which recommended as a high quality rice cultivars evaluated by blast nursery test, seedling test, and field screening and sequential planting methods. Sangmibyeo, Hwayeongbyeo, and Dongjin 1 were showed high resistance reaction to leaf blast at the blast nursery continuously, while Chucheongbyeo showed highest disease severity. All of the early maturing cultivars, Odaebyeo, Junghwabyeo, and Sangmibyeo, showed the lowest compatibility against 25 blast isolates. Saechucheongbyeo, a multiline variety of Chucheongbyeo genetic background showed 45.8%, half compatibility of 82.6% in Chucheongbyeo against 25 isolates screened. Diseased leaf areas (DLA, %) of cultivars were very low level at all test sites in the field test. Three cultivars, Sangmibyeo, Ilmibyeo, and Junghwabyeo didn’t show any leaf blast lesions across the test sites. The most variable incidences of panicle blast were observed on Odaebyeo which was 42.4%, 0.4%. and 0.0% at Jaecheon, Naju, and Chuncheon, respectively. In the sequential planting method, four rice cultivars, Nampyeongbyeo, Sindongjinbyeo, Hwayeongbyeo, and Junambyeo showed less than 40% disease leaf area (DLA) from 1st planting to 7th planting, so those cultivars were considered as a durable resistant rice cultivar against rice blast diseases.

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.

“Saebora” is a new leaf vegetable perilla (Perilla frutescens (L.) Britton) variety developed from a cross between “Ipdeulkkae1” and YCPL199 at the Yeongnam Agricultural Research Institute, NICS, RDA, in 2004. Purple backside leaf color is a very importan

“Sangbeak” (Perilla frutescens (L.) Britton), is a cultivar for leaf vegetable, from a cross between YPL5 (Ipdeulkkae1/ YCPL187) and “Namcheon” at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2003. The size of fully grown leaf is a important trait in delayed harvesting. The maximum leaf size of “Sangbeak” is 18.5cm, smaller than 21.4cm of a check cultivar, “Ipdeulkkae”1, leading to the constant leaf quality in delayed harvest. The fresh leaf yield of “Sangbeak” is 6% higher than that of “Ipdeulkkae 1” (5029 vs. 4742 kg/10a). For the leaf production, “Sangbeak” could be grown in whole area of South Korea. However, because of its late maturity, seed production culture is available in South Gyeongsang and South Jeolla provinces.
