보리에서 광호영 및 수축절수의 유전양식과 이들 두 형질의 연관관계를 구명하여 양질 다수성 품종개량의 효율 제고를 위한 기초자료를 얻기 위하여 호영이 넓고 수축절수가 적은 Triple Bearded Club Mariout(T.B.C.M) 품종과 호영이 좁고 수축절수가 많은 특성을 가진 강보리를 교잡하여 이들의 양친과 F_1, F_2세대 5개 조합을 공시하여 실험한 결과는 다음과 같다. 1. 보리의 광호영은 단순 열성으로서 1쌍의 대립유전자에 의해 지배되었다. 2. 수축절수는 많은 것이 우성, 적은 것이 열성으로서 1쌍의 대립유전자에 의해 지배되었다. 3. 수축절수와 호영을 지배하는 유전자는 동일염색체내 연관되어 있으며, 조환가는 조합마다 다소 차이가 있으나 15.8∼18.0% 범위로 비교적 가깝게 좌위하고 있는 것으로 추정되었다. This experiment was conducted to obtain basic genetic informations which could be used for breeding of barley for better quality an high yield. The data for this study were obtained from cross among Triple Bearded Club Mariout(T.B.C.M) and five released varieties. T.B.C.M. has wide outer glume and a low number of rachis internode, while five released varieties has narrow outer glume and a high number of rachis internode. The parents, F_1 and F_2 lines resulted from cross among T.B.C.M. and five released varieties were studied in field experiment. And the inheritance modes of outer glume, number of rachis internode, and their linkage relationships were determined. The wide outer glume in barley was a simple recessive gene. High number of rachis internode is shown to dominate over low number of rachis internode. The genes for number of rachis internode and outer glume appeared to be linked closely. Based on recombination analysis, recombination values between two characters linked were 15.8~18.0% with some variation depending on varieties used.
Development of a new forage winter oat cultivar for the mid-southern region of Korea

’Dahan’ (Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute of Crop Science (NICS), RDA in 2011. It was derived from an original cross between the F1 hybrid of ‘Sprinter’ and ‘73625’ and ‘Gwiri26’ (PA7507-37). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon. A line, ‘SO99027-GB-B-113-4-4-3’, was selected for cold tolerance and good agronomic characteristics and designated as a line name of ‘Gwiri75’. The line ‘Gwiri75’ was subsequently evaluated for cold tolerance, earliness, and forage yield in four different locations, Yesan, Iksan, Kimjae, and Jeju, from 2009 to 2011 and finally named as ‘Dahan’. Over 3 years, the average forage dry matter yield of ‘Dahan’ harvested at milk-ripe stage was 15.6 MT ha-1, compared with 14.1 MT ha-1 of check cultivar ‘Samhan’. Though similar in heading date to the check cultivar, ‘Dahan’ had tall plant length and lodging resistance. The feed value of ‘Dahan’ was superior to the check cultivar in percent total digestible nutrients (TDN) and TDN yield per ha. ‘Dahan’ is recommended primarily for winter planting use in the areas where daily minimum mean temperatures are averaged higher than -6 ℃ in January, and excluded in mountain area where frost damage is presumable.
Genetic Diversity of Soybean Landraces in Korea
Ouk-Kyu Han,Jun Abe,Yoshiya Shimamoto 韓國作物學會 1999 Korean journal of crop science Vol.44 No.3
To evaluate the genetic diversity and structure of the South Korean soybean population, 233 landraces collected in various regions of the country were surveyed for 15 allozyme loci and one protein locus. The South Korean population was fixed or nearly fixed at seven of the 16 loci tested. The number of alleles per locus was 2.06 and Nei’s gene diversity was 0.194. These values were lower than the values for the same 16 loci previously reported for the Japanese and Chinese populations. The differences among eight regional groups were not so marked, with only 7.2% of the total variation arising from regional differentiation. Three southern regional groups (Chollabuk-do, Chollanam-do and Kyong-sangnam-do) exhibited a relatively high variability because of frequent occurrence of alleles characteristic of the Japanese population. A marked difference was found in allelic frequencies at the Dial locus between large-seeded landraces and small-seeded ones, suggesting that the latter, which are used mainly for bean sprouts, had been established independently of the former, which are used mostly for soy sauce and cooking with rice. Not only the region but also the usage as food materials should therefore be taken into consideration in designing an efficient collection and preservation method for the Korean soybean landraces.
RFLPs of Mitochondrial DNA in Korean Wild Soybeans
Ouk-Kyu Han,Jun Abe 韓國作物學會 1999 Korean journal of crop science Vol.44 No.3
Mitochondrial DNA restriction fragment length polymorphisms are convenient markers for identifying cytoplasmic variation among plants. We have collected 212 wild soybeans (Glycine soja Sieb. et Zucc) from all over Korea, and classified mitochondrial genome types based on hybridization patterns in DNA gel-blot analyses using two mitochondrial DNA clones, cox2 and atp6, as probes. Korean wild soybean was classified with eight-mtDNA types, and some of the mtDNAs showed geographical clines among the regions. The diversity index of the mtDNA was much higher in the western and southern regions than in the eastern and northern regions of Korea, respectively. Dissemination and distributive characteristics of wild soybeans in Korea were discussed

신속한 서비스의 변경 및 처리를 위해서는 고객이 직접 개방된 운영시스템에 접속하여 신속하게 요청사항을 전달할 수 있어야 하며, 이러한 고객의 요청사항을 즉시적으로 전달망에 적용할 수 있어야 한다. 이러한 BcN 서비스 환경을 수용하기 위해서는 BcN 서비스 전달망에 대한 품질 제어가 가능한 구조수립이 필요하다. 본 논문에서는 가입자망 구간의 Flow-Based Router에서는 서비스별 트래픽 분리를 통하여 flow별 관리 기능과 개별 서비스 flow에 대한 실시간 트래픽 제어 기능을 통하여 차별화된 품질 보장을 제공한다. 또한 품질 제어 구조를 도입함으로써 최소한의 자원을 가지고 서비스 품질을 극대화 할 수 있게 함으로써 자원 효율성을 최적화하였다. In order to change and process service quickly, customers need to send service request by accessing an open operating system and it must be possible to alter the transmission network according to the service request. For that purpose, it is essential to build a system which enables a quality control on BcN service transmission network. This paper presents the way of providing quality of service through a traffic separation by the type of service at flow-based router and real-time traffic control on each service flow. Furthermore, resource utilization can be optimized by maximization the service quality with minimum resource due to the introduction of quality control structure.
