Cold sensitivity has been shown to vary and the cold tolerance from vegetative to reproductive stage appears to be independent during the life cycle. In the current study, cold tolerance under high elevation rice growing area were evaluated using F4 generation of 181 lines derived from Gayabyeo*2/Chhamrong. Five main-effect QTLs related to days to heading, panicle exertion and spikelet fertility were identified. The QTL qDH-3 on chromosome 3 showed the peak LOD score of 6.3, explaining up to 16.5% of phenotypic variation with additive effect of -2.6. Moreover, the QTL qPE-3 and qSF-3 on chromosome 3 were coincided with the QTL qDH-3 showing an opposite allele effects. Thus, the region harboring marker RM523-RM14281 could be helpful for the selection of cold tolerance genotypes in marker assisted selection(MAS) of rice breeding program.

“Yeonganbyeo”, a new japonica rice variety (Oryza sativa L.), is a mid- maturing ecotype with high lysine content in kernels that was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 2001 and released in 2002. This variety was originated from the single cross of Milyang 122/YR13616 Acp1 (in 1992/1993 winter) and was selected by means of a mixed method of bulk and pedigree breeding. The pedigree of “Yeonganbyeo” was YR15815-B-B-B-30 and designated in 1998 as “Milyang 164”. It has about 83cm in culm length with lodging tolerance. This variety is resistant to bacterial leaf blight (K1, K2, K3), stripe virus, and moderately resistant to leaf blast disease. Milled rice kernels of “Yeonganbyeo” has high lysine content of 4.31% (ratio of amino acid components in total protein), a clear translucent with non-glutinous endosperm and clear in chalkness and good at eating quality by pannel test. The yield potential of “Yeonganbyeo” in milled rice is about 5.45 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to the southern plain of Korea.

Cold tolerance at every growing stage of rice(Oryza sativa L.) is one of the main determinations for the stable growth in temperature and high elevate area. In the current study, a 181 lines of BC population derived from a cross of Gayabyeo, a Tongil type sensitive to cold and Chhamrong a tolerant to cold were evaluated for cold tolerance with cold water irrigation(17℃) at seeding stage as well as low temperature germinate at 13℃, respectively. The resulting linkage map consists of 157 marker loci, covering all of 12 rice chromosomes and spanning 910cM(Haldane function) with an average interval of 76cM between markers. Three main-effect QTLs were identified. The comparison of the OTLs identified in this cold treatments resulted in an intriquing finding that each treatments were controlled by a major QTL. The QTL qCWI-4 on chromosome 4 was found to increase its additive effect to -0.84 as the cold water irrigate stress was given. In the meanwhile, the QTL qLTG-8 was detected with a LOD score of5.54, explaining up to 13% of the phenotypic variation controlled by Gayabyeo allele. In addition, the QTL qLTGV-3, controlled by Gayabyeo allele with a LOD score of 5.19 explaining about 12.5% of the variation was also identified. These results would favor our better understanding of the genetic control of cold tolerance in rice and be important for the development of rice cultivars with a broaden climatic adaptation.

‘Danmi’, a sugary rice (Oryza sativa L.), was developed by the Department of Functional Crops, NICS, RDA in 2008. This variety was derived from a cross between ‘Sugary’ a genetic stock of germplasm as a source of sugary endosperm and ‘Seomjinbyeo’ in summer of 1994. The pedigree of ‘Danmi’ is YR16541-14-3-1-2-1-1-3-1-1 which was designated as ‘Milyang 227’ in 2005. Heading date of ‘Danmi’ is August 19, a medium-late maturing ecotype. The total sugar content of ‘Danmi’ was 21.7% with fructose (1.16%), glucose (7.87%), sucrose (9.69%), maltose (0.52%), and raffinose (2.13%), respectively. The appearance of grain is flat shape with 1,000 grain of brown rice is 16.1g. The yield potential of ‘Danmi’ in brown rice is 2.58MT/ha at ordinary fertilizer level of local adaptability test from 2006 to 2008. The sugary rice ‘Danmi’ would be adaptable to the plain paddy field of middle, honam and yeongnam province of Korea.

To fit the market demands for functional rice such as black and red color rice, ‘Sugary’a high free sugar content line was backcrossed to the black rice ‘Milyang152. The pedigree method was adapted in selection and generation advance. A high polyphenol content line, YR19646-3-2-1-1-2-2 showing red pericarp was selected and designed as ‘Milyang234’ followed by variety name ‘Geonganghongmi’ in 2010. Heading date of ‘Geonganghongmi’ was Aug. 19, medium-late maturing cultivar. ‘Geonganghongmi’ showed resistance to leaf blast and rice stripe virus while susceptible to major diseases and insects. The total polyphenol content of ‘Geonganghongmi’ was high as much as 24.2mg/g compare to that of 4.9mg/g of ‘Nampyeongbyeo’ and 17.2mg/g of a red pericarp rice ‘Jeogjinju’ at 70% ethanol extraction conditions. In local adaptability tests, yield of ‘Geonganghongmi’ was 4.5MT/ha about 86% of ‘Nampyeongbyeo’ and 102% of ‘Jeogjinju’, respectively. ‘Geonganghongmi’ is suitable for southern and middle plain area of Korea.

The advanced waste oil incinerator is suggested that has heat recirculation region in the combustor to burn out the waste oil completely in high temperature zone and heat recuperator in the left side of combustion cavity which plays a role of the flame stabilization of main burner flame by heat recovery of exhaust gas to incinerate waste oil contained water. In order to investigate a simultaneously incineration efficiency of the vessel waste oil contained the hazardous waste which occurs from the vessel and the sea outflow waste oil experiments have been carried out using the emulsion fuel mixed the water and bunker fuel oil C and the blend mixed the light oil and the waste surrogate material (acetonitrile:CH_(3)CN). The results of experiments showed that the waste oil incinerator developed in this study was excellent for the incineration efficiency of waste oil at an air ratio of 1.46 and DRE (destruction and removal efficiencies) of CH_(3)CN was 99.9996% ("5 nines"). And optimum operating conditions for the secondary air flow rate of internal mix burner, preheating temperature and injection point of shipboard waste oil contained acetonitrile were suggested.
