AND INVESTIGATION OF PRINCIPAL CHARACTERS FOR GERMPLASM CONSERVATION IN KOREA Yeon-Sang Song*, Seon-Kyeong Han, Youn-Ho Moon, Byeong-Choon Jeong, and Jin-Ki Bang *Mokpo Experiment Station, National Institute ofCrop Science (NICS), RDA 293-5 Cheongcheon Cheonggye Muan Jeonnam, 534-833 Korea Tel: +82-61-450-0120, Fax: +82-61-453-0085, E-mail: [email protected] Summary This study was carried out to collect, propagate the excellence native tea plants, and investigate the principal characters as a genetic resources for tea plant breeding and gene conservation from 2004 to 2006 in Korea. The seeds (143 kg) and cuttings (16,700 cuttings) were collected from 120 locations for three years in the Southern area ofKorea. The results of evaluation after planting of collected gennplasm, index of leaf shape showed as 2.5. Leaf color showed same level after planting regardless collected regions, though they were differed from each other in their original region. Negative correlation was observed in the number of stem and stem length, number of leaf. Several chemical components such as tannin, total nitrogen, caffeine, and catechins were analyzed. Ninety-six percent of the surveyed 293 accessions had mainly 2.2 to 6.3% total nitrogen content. The tannin content was distributed mainly from 5 to 15%. Based on these data, we selected twenty two accessions and propagated to tea plant breeding. The Korean wild tea accessions showed high caffeine, EGC, and ECGC contents. Low caffeine tea plants were observed in Naju and Jangseong county, and the regions with high amino acid content were observed in Yeongam and Muan county. Keywords: Tea plant, germplasm, collection, characteristics Introduction In Korea, more than 80% of total tea gardens were made with seed born plant which have low productivity of tea leaf. In order to improve productivity oftea leaf, tea garden should be made with clone cultivars. The matter must be settled without delay. Thus, we collected variable genetic resources from around of Korea and analyzed. In addition, important characteristics such as the morphological and chemical components of tea leaves were evaluated and structured to data base for tea breeding program ofsuperior cultivar. Therefore, we reports here some results obtained surveying the characteristics of the wild tea plants collected from all around ofKorea. Materials and Methods We surveyed morphological characteristics (No. of leaf, leaf color, No. of stem, stem length) and chemical components (total nitrogen, tannin, caffeine, catechins) after transplanting those in same field. The total nitrogen was analyzed from powdered dried leaves using Kjeldatherm (Gerhardt). For tannin analysis, Sakai's (1974) labor-saving method was used. The preparation method of samples was modified from previous HPLC analysis (Sharma et aI., 2005; Yao et aI., 2004). Total 293 accessions were selected and analyzed to understand the characteristics ofKorean wild tea plants. Results 126· 127· 129· 37· 36· 35· Fig 1.

  • New Challenges Facing Asian Agriculture Under Globalisation
    New Challenges Facing --------1-------- Asian Agriculture under Globalisation Volume II Edited by Jamalludin Sulaiman Fatimah Mohamed Arshad Mad Nasir Shamsudin 34 Farm Household Debt Problems in Jeonnom Province, Korea: ACose Study J.K. Park, P.S. Park and K.H. Song Introduction Farm loans have increased quite rapidly in the recent decades and the farm household debt 1 matter has become a serious socio-economic issue in Korea. In an effort to get around this critical issue, the government would prepare and implement impromptu new debt measures. Yet, the farm-debt ratio over farm income has been increasing very rapidly since the beginning of the WTO in 1995 and the IMF financial crisis of 1997, leading to 88 per cent as that of 2000, mainly due to low agricultural income. During the period of 1994 (the year right before the beginning of the WTO)-2000, farm household income had increased by 13.6 per cent but debt had increased by as much as 156.3 per cent (MAF, 2001 ). That is, farm household debt has been increasing very rapidly since 1995. Yet, the ratio of non-farm income accounted for around 32 per cent of farm income in recent years, which made it more difficult for farmers to repay their loans. This problem is getting even more complicated because of joint surety among the farmers, which would lead to total bankruptcy of farms including financially sound farms. Recently, more than 7 5 per cent of farm loans were utilised for the purpose of agricultural production. In order to cope with labour shortage problems due to the rural-urban migration of labour force, farmers began to purchase more agricultural machinery, which eventually led to the galloping farm household debts.

    Mycobiology Research Article Phylogenetic Placement and Morphological Characterization of Sclerotium rolfsii (Teleomorph: Athelia rolfsii) Associated with Blight Disease of Ipomoea batatas in Korea Narayan Chandra Paul, Eom-Ji Hwang, Sang-Sik Nam, Hyeong-Un Lee, Joon-Seol Lee, Gyeong-Dan Yu, Yong-Gu Kang, Kyeong-Bo Lee, San Go and Jung-Wook Yang* Bioenergy Crop Research Institute, National Institute of Crop Science, Rural Development Administration, Muan 58545, Korea Abstract In this study, we aimed to characterize fungal samples from necrotic lesions on collar regions observed in different sweetpotato growing regions during 2015 and 2016 in Korea. Sclerotia appeared on the root zone soil surface, and white dense mycelia were observed. At the later stages of infection, mother roots quickly rotted, and large areas of the plants were destroyed. The disease occurrence was monitored at 45 and 84 farms, and 11.8% and 6.8% of the land areas were found to be infected in 2015 and 2016, respectively. Fungi were isolated from disease samples, and 36 strains were preserved. Based on the cultural and morphological characteristics of colonies, the isolates resembled the reference strain of Sclerotium rolfsii. Representative strains were identified as S. rolfsii (teleomorph: Athelia rolfsii) based on phylogenetic analysis of the internal transcribed spacer and large subunit genes along with morphological observations. To test the pathogenicity, sweetpotato storage roots were inoculated with different S. rolfsii strains. ‘Yulmi’ variety displayed the

  • Lunar New Year Macarthur, General Douglas
    894 Lunar New Year The lunar New Year, known as 561, W6ndan, W6ni! or Cbongch '0, is one of the most important holidays in Korea. During this holiday, there are traffic jams throughout the country as people rush to see their family and relatives. On the morning of Lunar New Year, people don traditional dress (hanbok). Various foods and wine are prepared, and then set in front of an ancestral tablet. The table is meticulously arranged according to Confucian tradition; however, many families also have their own traditions governing details of the arrangement. In general, fish is put on the east, meat on the west, fruit in front, rice and soup behind and liquor on the front table. A ceremony is then held during which the male family members pay respect to their deceased ancestors up to the fourth generation by making three full bows. Family members also visit the graves of their deceased ancestors. On this holiday, after cutting the grass from around the grave, they make a simple offering and then bow three times. In addition to paying respect to the deceased, each family member is expected to make two formal bows to his or her elders. According to custom, the elders then give the person a gift of money, particularly if the person is a child. Special foods are prepared for this holiday. In particular, rice-cake soup is typically served instead ofrice. For this reason, the question 'How many bowls of rice-cake soup have you eaten?' is sometimes used to ask one's age. In North Korea and China, mandu (dumpling) soup is often eaten instead.

In this study, we propose urban disaster prevention plans based on the classification and characterization of flood vulnerable areas reflecting demographic changes. Data on the property damage, casualties, and flooded area between 2009 and 2018 in 229 municipalities in South Korea were collected and analyzed, and 74 flood vulnerable areas were selected. The demographic change in the selected areas from 2000 to 2018 was examined through comparative analyses of the population size, rate of population change, and population change proportion by age group and gender. Flood vulnerable areas were categorized into three types through K-mean cluster analysis. Based on the analysis results, a strategic plan was proposed to provide information necessary for establishing regional flood-countermeasure policies. Keywords: urban disaster prevention plan; flood vulnerability; climate change; demographic change; cluster analysis 1. Introduction Floods are one of the most dangerous and destructive natural hazards that can cause human loss and economic damages [1–3]. Climate change is expected to increase the frequency of flooding and the extent of damage caused by it [4–6].

  • A Predictive Model for Estimating Damage from Wind Waves During Coastal Storms
    water Article A Predictive Model for Estimating Damage from Wind Waves during Coastal Storms Yeon Moon Choo , Kun Hak Chun, Hae Seong Jeon and Sang Bo Sim * Department of Civil and Environmental Engineering, Pusan National University, Busan 46241, Korea; [email protected] (Y.M.C.); [email protected] (K.H.C.); [email protected] (H.S.J.) * Correspondence: [email protected]; Tel.: +82-051-510-7654 Abstract: In recent years, climate abnormalities have been observed globally. Consequently, the scale and size of natural disasters, such as typhoons, wind wave, heavy snow, downpours, and storms, have increased. However, compared to other disasters, predicting the timing, location and severity of damages associated with typhoons and other extreme wind wave events is difficult. Accurately predicting the damage extent can reduce the damage scale by facilitating a speedy response. Therefore, in this study, a model to estimate the cost of damages associated with wind waves and their impacts during coastal storms was developed for the Republic of Korea. The history of wind wave and typhoon damages for coastal areas in Korea was collected from the disaster annual report (1991–2020), and the damage cost was converted such that it reflected the inflation rate as in 2020. Furthermore, data on ocean meteorological factors were collected for the events of wind wave and typhoon damages. Using logistic and linear regression, a wind wave damage prediction model reflecting the coastal regional characteristics based on 74 regions nationwide was developed. This prediction model enabled damage forecasting and can be utilized for improving the law and policy in disaster management.
