        몽골의 식물 유전자원 연구현황

        임무상,바이에르숙,백형진,이석영,이동진 한국국제농업개발학회 1997 韓國國際農業開發學會誌 Vol.9 No.4

        몽골에서는 1920년대부터 러시아와 공동으로 식물 유전자원을 탐색, 수집하였으며 이들을 재료로 1950년대부터는 품종을 육성하였다. 다칸의 식물학 및 농업연구소는 1979년에 설립되어 10년 장기계획을 토대로 식물유전자원 연구를 실시하였는바, 다양한 농업생태 지역을 바탕으로 육종모본이 될 작물들을 수집하였다. 현재 다칸의 식물 및 농업연구소에는 밀 8,448점, 보리 4,423점, 귀리 1,672점 등 총 21,132점이 상온에 보존되어 있고 그중에 1,200점은 연구소 자체, 국제기관 또는 국제협력에 의해 수집된 재래종이다. 1991년에는 5개년 계획으로 식물유전자원의 수집, 도입, 안전보존, 평가, 교환, 정보화 및 이용 등에 대하여 진행되고 있다. 이들 자원에 대한 연구는 다칸의 식물학 및 농업연구소를 중심으로 Choibalsan의 동부지역 농업연구소, Hovd의 알타이지역 농업연구소, Ulaangom의 서부지역 농업시험장, 울란바타르의 가축사양연구소 등과 협력적으로 운영되고 있다. 유전자원에 대한 국가적인 전략은 작물의 생산성 향상, 환경내성 품종 육성을 위한 야생근연종 등 다양한 자원의 확보와 현지내의 보존 및 장,단기보존 방법의 개발, 전문가양성 및 외국과의 공동연구를 통한 종자 및 정보의 교환에 역점을 두고 있다. In Mongolia, collection and exploration of traditional crop genetic resources was initiated in 1920s with the assistance of Russian researchers and first local varieties have been developed through breeding programmes. from 1950s With the establishment of Plant Genetic Resources(PGR) Section at Plant Science and Agricultural Research Institute(PSARI) in 1979, comprehensive preservation, exploration and collection of PGR was started on a regular basis and First 10 Year Programme for PGR exploration was launched. The programme involved collection, introduction and exploration of crop genetic resources in different agro-ecological zones to develope initial materials for breeding, enrich crop species with new varieties and identify suitable agroecological zones for crop production. In 1991, a new Five Year National Programme for PGR was started. This programme involved the collection, introduction, preservation, evaluation, exchange, documentation and utilization of PGR. All of the agricultural research institutes of Mongolian National Agricultural University(MNAU) are participating in this programme. In 1992, the National Board of PGRNBPGR) was established to address the urgent need for the coordination of the activities in the managment of PGR in Mongolia.

      • 農業技術革新 硏究開發의 體系分析的 硏究

        王仁槿,洪哲善,林茂相 서울大學校 農科大學 1983 서울대농학연구지 Vol.8 No.1

        The empirical study of the agricultural R & D for technological innovations by the application of the so-called systems analysis approach was first of its kind of research efforts ever implemented in Korea if we researchers correctly understood. In the light of this fact and others, such as the constraints of research resources made available and found within our reach, this pioneering research study had to be a case study with the Crop Experiment station of the Office of Rural Development located in Suweon. The research results reported here were based on partial analyses though consisting of the essentially central and substantive ones. The research method employed by which the data and information for the research study were collected was the distributed questionnaires on which the respondents, the total enumeration of the research staff of the Station headquarters, were individually and personally requested to check appropriately. The total number of the questions contained in the printed questionnaire was more than one hundred and thirty,covering eight categories including that for the background information on the respondents. A. Some of the more important findings of the research study than others within the manageable scope for this research report were as follows in a rigorously abstracted form: 1. With respect to the decision-making on the selection of research projects, it was revealed that thr researchers'participatory satisfaction was significantly high though they complained their superiors, within and outside, did influence the decision outcome. 2. It was found that the budget allocated for the research projecs finally selected was perceived as below the appropriate level professionally considered. Furthermore, the respondents made it clear that the implementation of the research projects was not made smoothly as it should be done, especially in the case of the budget execution. 3. The sample researchers for the agricultural production innovation determined that the

        水稻品種의 出穗生態에 關한 硏究

        M.S. LIM(林茂相) 한국육종학회 1981 한국육종학회지 Vol.13 No.2

        Several investigations were undertaken with 78 rice varieties of Korean leading cultivars and some important breeding materials to clarify the nature of heading fluctuations due to the different sets of the climatic conditions with years and seasons, to estimate the heading duration from transplanting to heading under various locations and seasons in rice culture, and to classify the understandable ecotypes of the Korean rice varieties for rice breeders and agronomists in Korea. Twenty-day seedlings were transplanted in the paddy field from early May to August with 10-day intervals under the ordinary fertilization. Heading dates were recorded and analyzed with the climatic factors on the varietal bases. The results obtained are summarized as follows: 1. The standard partial regression analysis for the effect of the climatic factors affecting to the heading durations indicated that there were single and interaction effects among the various climatic factors to the heading duration. 2. The covariance analysis revealed that there were not any significant interactions among average air temperature, sunshine hours, and day length. Thus these three factors were mainly used for the multiple regression equations to estimate the growth duration of the rice cultivars in Korea. 3. The climatic index in terms of number of days, which affect the growth duration of the individual varieties, were estimated through six years. 4. The year variations of heading duration were great as well as the seasonal variations, and the degree of variations differed from variety to variety. 5. The critical temperature which did not affect the heading duration was estimated as 18.2℃. Most of the Korean rice varieties showed their shortest growth duration under the day length of 13.5~14.5 hours, which suggested that most of the Korean rice varieties were little sensitive to the photo-period while more than half of the tested varieties were affected in their heading duration by the day length at significant levels. 6. Except some inadequate Hokkaido varieties and the non-sensitive varieties, the heading durations could be estimated by the regression equations when adapted them to the individual varieties. 7. The regression equations obtained both through several years and various seasons on the varietal bases could be adapted to the areas within the latitude of 37±3°N, regardless of the years and seasons. 8. The regressions obtained from the specific year were well adapted to the year but the regressions from the long-term experiments were adapted much better to wide range of years am seasons even though there were deviations. 9. From the regression equation on the individual variety, the range of adaptable locations could be justified and the heading delay due to the irregularly fluctuated temperatures on the variety could be estimated. 10. The ecotypes can be classified into 29 groups based on their basic vegetative growth duration, relative eliminable growth duration, and significance of the photo and thermo effect to the heading duration within the range of tested varieties and climatic regulations under field conditions in Korea. In this case, only 18 groups of the ecotypes could be adopted to the 78 tested varieties.

        등숙 진전에 따른 도체내 부위별 양분 동태에 관한 연구 I. 도체내 부위별 무기양분의 동태

        이양구,임무상,임병기,Lee, Yang-Ku,Lim, Moo-Sang,Im, Byeong-Gi 한국작물학회 1986 한국작물학회지 Vol.31 No.2

        In order to clarify the trend of change in mineral nutrients in rice plant on various ripening process, P$_2$O$\sub$5/, K$_2$O, MgO, CaO, SiO$_2$ and ash contents were determined for the grain, internode, leaf-5heath and leaf blade respectively for 9 times at an week interval after heading. Four rice cultivars with different maturity and ecotype were grown under normal cultural conditions for the trial. The contents of mineral nutrients in the brown rice were in the order of Ash, P$_2$O$\sub$5/, K$_2$O and MgO. CaO and SiO$_2$ were found in minute quantity in the brown rice. The hull contained SiO$_2$ in large quantity, and it also contained the mineral nutrients in the order of K$_2$O, P$_2$ O$\sub$5/O. The CaO content of hull was extremely minute.
