The objective of this study is to examine the regional distribution of Ssireum(Traditional Wrestling) of South and North Korea in the Japanese colonial era. The conclusions of this study are as follows. First, the "Joseon ui hyangto orak(Folk play in Joseon)" showed the record of performing 272 times of Ssireum in 226 regions of the whole nation. Second, the Ssireum of South Korea could be divided into five regions. Seoul/Gyeonggi-do performed Ssireum the most in Dano, Baekjung, and Chuseok while Chungcheong-do performed Ssireum in Baekjung and Chuseok. Jeolla-do and Gyeongsang-do performed Ssireum in Chuseok while Gangwon-do performed Ssireum in Dano and Chuseok. Third, the Ssireum of North Korea could be divided into three regions. All the Hwanghae-do, Pyeongan-do, and Hamgyeong-do performed Ssireum the most in Dano. Fourth, as the period when Ssireum was held the most in the whole nation, Dano, Baekjung, and Chuseok could be pointed out. Ssireum has the characteristics of large-scale play between village communities or regions, instead of individual game. Thus, the Ssireum that was played as a sport event under certain rules for a long time was settled down as a folk play of regional festivals such as Dano, Baekjung, and Chuseok. Fifth, as a folk play and a representative play of seasonal customs, Ssireum was distributed in the whole nation and handed down till today under the regional deviation of South and North Korea. Sixth, the unidentified regions of South Korea that did not perform Ssireum were six places including five dos such as Gapyeong Gyeonggi-do, Boseong Jeollanam-do, Jeju-do, Gunwi and Cheongsong Gyeongsanbuk-do, and Inje Gangwon-do. The regions of North Korea were six places including three dos such as Pyeongyang, Yangdeok, Gangdong, and Gaecheon of Pyeongannam-do, Bakcheon Pyeonganbuk-do, and Dancheon Hamgyeongnam-do. Total 12 places in eight regions were included. Seventh, the number of total items of play names presented in the "Joseon ui hyangto orak(Folk play in Joseon)" was about 6,400 types. Out of them, about 1,300 types were the items including how to play while about 5,100 types were the items presenting the play names only without explanations. Especially, in case of Ssireum, the periods of the lunar calendar were only specified in each region. Unfortunately, it was not possible to check the contents about the actual performance methods and types of Ssireum as they were omitted.

'Baekjung' adaptable to high temperature was made by crossing between monokaryon derived from selfing of brown strain and monokaryon derived from Korea white strain. In the condition that temperature is maintained at $10^{\circ}C$ without low temperature of $4^{\circ}C$ suppressing treatment and wrapping during cultivation period, it showed good productivity than Uri1ho(control). The optimum temperature of mycelial growth was $30^{\circ}C$ and that of fruiting body initiation and development were $14^{\circ}C$ and $7^{\circ}C$, respectively. The days for the fruiting and yield were 7 days and $277{\pm}11.2$ g per 1,100 ml bottle, respectively. This variety needed high concentration of carbon dioxide up to 4,000 ppm for the good quality.

High temperature is one of major environmental stress. Heat in flowering season of wheat is able to effect negatively to fertilization and also heat effect to maturity. Therefore, Heat stress effects severely to qualities of wheat and yield productivity. In this study, we evaluated to agronomic characteristics and qualities by high temperature in 13 Korean wheat varieties. Weight of 1,000 grains decreased when wheat got the heat stress. In particular, heat stress during the heading dates were more damaged than after the end of heading dates except two varieties Keumkang and Jokyoung. Plant height of each cultivar under high temperature and normal field averaged 80.5 cm and 83.0cm, respectively. The length of spike and awn in each cultivar were similar to both condition. Flour yield and gluten contents of most heat damaged wheat decreased. Under the temperature, protein contents of six varieties like as Keumkang, Baekjoong, Hojoong, Yeonbaek, Joah and Shinmichal 1 decreased but the others increased. The sedimentation values (SDSF) of four varieties decreased under the high temperature. But SDSF of 7 varieties like as Baekjung, Suan, Hojoong, Jojoong, Uri, Shinmichal and Shinmichal 1 was increased. The lightness (L) of wheat flour derived from high temperature treated wheat was darker than non-treated wheat. As a result of this research, we confirmed that agricultural traits and qualities decreased in heat damaged wheat.

Salinity in surface waters is increasing around the world. Many factors, including increased water extraction, poor irrigation management, and sea-level rise, contribute to this change, and posing a threat to plant development and agricultural production. Seeds exposed to high salinity, have a lower probability of germinating and various physiological and biochemical effects. Salinity stress affects more than 20% of agricultural land and about 50% of irrigated land. In the current study, our objective is to identify the salt-tolerant peanut (Arachis hypogaea L.) Korean genotypes under salinity stress. Thus, two-week-old 19 diverse peanut Korean genotypes were exposed to 10 days of salinity (150 mM NaCl) stress. Based on the growth attributes investigation, Baekjung and Ahwon genotypes showed significantly higher shoot lengths compared to control plants. Whereas, the Sinpalwang genotype exhibited a significantly positive response for plant growth and reduced wilting symptoms compared to other genotypes. This study was able to find out peanut tolerant and sensitive genotypes for salt stress. These results may provide a good template for further salt-tolerant peanut cultivar improvement programs. Identified diverse salt-responsive genotypes can be utilized as source material in Korean breeding schemes for peanut crop improvement for salt and other abiotic stress tolerance.

This study was performed to offer basic data base on traditional Korean festival foods for a traditional Korean food data integration system, that is based on literature reviews. The Korean lunar calendar has seasonal divisions reflecting traditional Korean holidays. In the past, there were many customs corresponding to emotions, and foods were in accordance with customs, festivals, and seasons. Today, we are well aware of the traditional Korean foods of New Year's Day(Seollal), the Korean Harvest Festival(Chuseok), the First Full Moon Day(Jeongwol Daeboreum), the Winter Solstice(Dongji), and the hottest summer day(Sambok). However, many other traditional Korean holidays are disappearing from the modem Korean life-style. This study made the following classifications for traditional Korean festivals. Seollal(Seol), Ipchun, and Jeongwol Daeboreum in January; Junghwajeol in February; Samjinnal in March; Hansik and Chopail in April; Dano in May; Yudu and Sambok in June; Chilseok and Baekjung in July; Chuseok in August; Jungyangjeol in September; Siwolmuoil in October; Dongji in November; and Napil and Seotdal Geumeum in December. The familiar traditional Korean festival foods are as follows: Seollal's festival foods consist of 5 main dishes, 35 side dishes, 12 kinds of tteok lyou, 21 kinds of hangwa lyou, 2 kinds of emchong lyou, and 3 kinds classified as others; this includes tteokguk, manduguk, galbijjim, sinseollo, jeon, pyunyuk, kimch, tteok, sikhe, sujunggwa, fruits, and seju on Seollal. The festival foods for Jeongwol Daeboreum consist of 3 main dishes, 27 side dishes, 5 kinds of tteok lyou, 3 kinds of hangwa lyou, 4 kinds of emchung lyou, and 3 kinds classified as others; this includes ogokbap, mugeunnamul, yaksik, yumilkwa, wonsobyung, guibalgisul, and burum on Jeongwol Daeboreum. The festival foods for Sambok consist of 6 main dishes, 18 side dishes, 4 kinds of tteok lyou, 3 kinds of eumchung lyou, and 2 kinds classified as others; this includes yukgaejang, imjasutang, youngyejjim, tteoksudan, santtalgihwaschae, and subak on Sambok. Chuseok's festival foods consist of 4 main dishes, 22 side dishes, 18 kinds of tteok lyou, 6 kinds of hangwa lyou, 4 kinds of eumchung lyou, and 3 kinds classified as others; this includes oryeosongpyeon, toranatang, garijjim, dakjjim, namuls, tteok lyou, baehwachae, and fruits on Chuseok. The festival foods for Dongji consist of 6 main dishes, 6 side dishes, 7 kinds of tteok lyou, 1 kind of hangwa lyou, 2 kinds of eumchung lyou, and 1 kind classified as others; this includes patjug, jeonyak, and dongchimi on Dongji. Based on these data, it is recommended that knowledge of traditional Korean festival foods be handed down, preserving and develop their excellence and to further scientific studys.

Flammulina velutipes, which is a white rot fungus, is a commercially important edible mushroom and is produced in large quantities with the help of an automated and mechanized cultivation system in Korea. F. velutipes has the lowest distribution rate among domestic cultivars, estimated at about 20 percent. As most white cultivars of F. velutipes produced and exported to Korea were introduced from Japan, farmers pay large amounts of royalties. Therefore, we have developed a new, purely domestic cultivar, "Baeke," to substitute for Japanese cultivars, which has improved storage characteristics for export. Baeke was bred by mating two monokaryotic strains isolated from ASI 4216-18 (Hansol) and ASI 4217-26 (Baekjung). Baeke showed faster mycelial growth and higher mycelial density upon incubation for seven days at $25^{\circ}C$ on PDA media than the control variety. The mycelial growth of Baeke was even maintained at $30^{\circ}C$ unlike the control. The lengths of pilei and stipes in Baeke harvested in the optimal stage were $11.2{\pm}0.5mm$ and $125{\pm}5.4mm$, respectively, and they were $11{\pm}0.5mm$ and $141.9{\pm}5.7mm$, respectively, in the control harvested in the optimal stage. The yields of Baeke ($257.4{\pm}13.5g$) and control ($270.7{\pm}17.8g$) per 1,100ml in bottle cultivation showed no significant difference. Overall, our results showed that Baeke was at par with foreign varieties of Flammulina velutipes in terms of quality and yield and had a uniformly shaped fruitbody, which added to its commercial value.

Agrobacterium-mediated transformation (AMT) is a method that allows for the stable integration of DNA fragments into the plant genome. Transgenic plants generated through AMT typically exhibit a lower copy number of the transgene compared to those induced by particle bombardment. Furthermore, AMT offers a straightforward and efficient approach for generating transgenic plants. While the transformation efficiency of wheat is comparatively lower than that of other monocot plants such as Rice (Oryza sativa L.) and Maize (Zea mays L.), the cultivars 'Bobwhites' and 'Fielder' are commonly employed for wheat transformation. To date, there have been no reported instances of successful development of transgenic plants using Korean wheat varieties through AMT. This study aims to assess the transformation efficiency of 43 Korean wheat cultivars using the GUS assay, with the goal of identifying suitable Korean wheat cultivars for AMT. The pCAMBIA1301 vector, carrying the β-glucuronidase (GUS) gene, was incorporated into Agrobacterium strain EH105. Following the inoculation of Agrobacterium into immature embryos, GUS assays were conducted 'Saeol', 'Jopum', and 'Jonong' showed 100% (the number of embryos showing GUS spots/the number of embryos used for AMT) among 43 cultivars. In addition, cultivars with more than 70% were 'Saekeumgang', 'Jojung', 'Tapdong', 'Anbaek', 'Dabun', 'Sugang', 'Keumgang', 'Jeokjung', 'Seodun', 'Joeun', 'Dajung', and 'Baekjung'. It seems that the 15 cultivars above showed the possibility of using AMT. On the other hand, 'Yeonbaek', 'Goso', 'Baekgang', and 'Johan' showed less than 20% and GUS spots were not observed in 'Gru', 'Gobun', 'Milseong', and 'Shinmichal-1'. This study explores transient GUS expression in Korean wheat cultivars seven days after AMT. The observed initial high efficiency of transient transformation suggests the potential for subsequent stable transformation efficiency. Korean wheat cultivars demonstrating elevated transient transformation efficiency could serve as promising candidates for the development of stable transgenic wheat.
