A new rice variety ‘Dongbo’ is a japonica rice (Oryza sativa L.) with good eating quality, lodging tolerance, and resistance to rice stripe virus (RSV) and blight bacterial disease (BB). It is developed by the rice breeding team of Yeongdeog Substation, National Institute Crop Science, RDA in 2010. This variety derived from a cross between ‘Yeongdeog19’ with good grain quality and wind tolerance and ‘Koshihikari’ with good eating quality conducted in 1996 summer. A promising line, YR18320-21-1-1-2-2-2, selected by pedigree breeding method was designated as the name of ‘Yeongdeog49’ in 2007. After the local adaptability test was carried out at nine locations from 2008 to 2010, ‘Yeongdeog49’ was released as the name of ‘Dongbo’ in 2010. ‘Dongbo’ is short culm length as 71cm and medium-growth duration. This variety is resistant to races, K1, K2, and K3 of bacterial blight and stripe virus and moderately resistant to leaf blast disease with durable resistance, and also has tolerance to unfavorable environment such as cold and dried wind. ‘Dongbo’ has translucent and clear milled rice kernel without white core and belly rice, and good eating quality as a result of panel test. The yield potential of ‘Dongbo’ in milled rice is about 5.71 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to middle plain, mid-west costal area, and south mid-mountainous area.

시설 및 노지에 재배되는 소득작물은 종류가 다양하고 장소와 시장가격 동향에 따라 수확시기가 극히 가변적이다. 따라서 소득작물 후작에 필요한 벼는 늦게 심어도 벼를 안정적으로 수확할 수 있는 단기성 품종이어야 한다. '만종'은 '영덕34호'와 '남평벼'를 각각 모본과 부본으로 인공교배 한 후 약배양으로 품종을 육성하였다. 1. 출수기는 7월 10일에 이앙한 ...소득작물 후작지 재배에서 8월 30일로 '금오벼'보다 1일 정도 늦은 중생종이다. 간장은 '금오벼'
Manjong' is a new japonica rice cultivar developed in 2009 derived from a cross between 'Yeongdeog34' and 'Nampyeongbyeo' at the Department of Functional Crop, NICS, RDA. This cultivar is suitable for the double cropping system after the cash crop cultivation. Heading date of 'Manjong' is later than 'Keumobyeo'under the late transplanting cultivation on July 10. It has high grain fertility under cold conditions and low premature heading. One of the distinguishing characteristics of this variety is its resistance to major diseases like leaf blast and rice stripe virus disease. However, it shows susceptibility to major insect pests and bacterial blight disease. Milled rice kernels are translucent with non-glutinous endosperm and have 7.2% protein and 18.7% amylose contents. Ripening ratio and head rice ratio is very higher than those of 'Keumobyeo'. The palatability of cooked rice is also better than 'Keumobyeo'. The milled rice yield of 'Manjong' in local adaptability tests after harvest of the cash crop is 4.81 MTha-1. This cultivar is suitable for planting in the plain paddy fields of Honam and Yeonnam regions in Korea.

A new rice cultivar, ‘Joami’, was developed by the rice breeding team of Sangju Substation, National Institute of Crop Science (NICS), Rural Development Administration. It was selected by a bulk and pedigree methods from a cross-combination among ‘Sambaegbyeo’, ‘Yukara’, and ‘Tonggae112’. A promising line of YR20557-1-1-3-B-3 was designated as ‘Sangju 36’ in 2006. Local adaptability test of ‘Sangju 36’ was conducted at ten sites throughout the Korean peninsula during three years from 2006 to 2008. ‘Sangju 36’, thereafter, was registered as ‘Joami’ in 2008. The cultivar headed on July 30 in the test of local adaptability. Endosperm of ‘Joami’ is translucent with clear chalkiness and has 5.4% higher head rice ratio than that of ‘Odaebyeo’. The yield potential of ‘Joami’ in milled rice is about 5.40 MT/ha under ordinary fertilizer level of local adaptability test, which was 6% higher than that of ‘Odaebyeo’. In an alpine area of Korea, the rice variety needs a cold tolerance and a resistance to blast disease. ‘Joami’ showed a tolerance reaction at Chuncheon cold tolerance screening nursery and exhibited resistance reaction to blast disease in nation-wide disease screening nursery. Therefore, ‘Joami’ would be well adaptable to mid-mountainous area at central and southern part of Korean peninsula.

Journal Article
Neuropeptide Y (NPY) is located in the olfactory system, including the olfactory bulb, and is thought to be one of the main neurotransmitters for olfaction. Thus, we examined age-related changes of ...NPY-immunoreactive (IR) neurons in the rat anterior olfactory nucleus (AON) at various aging stages over a period of 2 years; postnatal months 1 (PM 1), PM 6, PM 12 and PM 24. NPY-IR neurons in the AON were present in the lateral and medial subdivisions at PM 1 and at PM 6 were distributed in all subdivisions of the AON. Prior to PM 12, the NPY-IR neurons showed a tendency to change from bipolar cells with short processes into multipolar cells with long processes. Moreover, the population of NPY-IR neurons and nerve fibers in the AON increased in proportion to age. In particular, the number of NPY-IR neurons increased about 6-fold between PM 1 and PM 3. At PM 24, the number of NPY-IR neurons was much smaller than that at PM 12 and somal size had decreased. It is therefore suggested that the dramatic increase in the number and size of the NPY-IR neurons between PM 1 and PM 3 may be associated with sexual maturation and that the decrease in the number and cell size of the NPY-IR neurons at PM 24 may underlie age-related changes in the olfactory process.
