Doo Chull Shin(申斗澈),Moon Kap Joo(朱門甲) 한국육종학회 1986 한국육종학회지 Vol.18 No.4

This study was conducted to confirm the germinability of unripened seeds for rapid generation advancement of soybean in field and greenhouse. Seed development and germinability were faster in greenhouse than in field, and in the early variety than in the late variety. The first germinabilities were found on the 20 days after flowering(DAF) in greenhouse materials, and on the 20 to 25 DAF in field materials. It was found that over 90 percentage of germination on 10 to 20 days before maturity of soybean in field and greenhouse, and this ripening stage was corresponded with the time when the fresh pod weight reached at the highest level. The germination ratio of the seeds dried with pod shell was the almost same level with that of the fresh seeds ripened for 10 to 15 days more. The germination ratios of the dried seeds which were harvested on 20 to 25 days before maturity in each cultivar were over 80 percentage.

Doo Chull Shin,Arnold T. Tschanz 韓國作物學會 1986 한국작물학회지 Vol.31 No.4

열대 및 아열대지역의 대두재배에서 수량을 격감시키고 있는 콩녹병에 대한 내병성품종과 이병성품종을 공시하여, 본 병해의 진전과정과 생리적 및 수량관련형질에 미치는 영향을 검토한바 그 결과를 요약하면 마음과 같다. 1. 이병성품종은 내병성품종에 비하여 병의 조기감염 및 진전이 빨랐으며, 녹병에 의한 낙엽은 콩 꼬투리가 반정도 등숙된 후부터 급격히 증가하였다. 2. LAI의 감소는 이병성품종이 내병성품종에 비하여 빨랐으며, 건전개체와 녹병 이병개체간의 엽녹소함양의 차리는 내병성품종에서 2.04%, 이병성품종에서 16.43%의 차이가 있었다. 3. 지상부 건물중은 녹병무발병구(살균제 처리구)에서는 계속 증가하였으나, 녹병발병구에서는 R6 생육단계 이후부터 감소하였고, 감소정도는 이병성품종이 내병성품종에 비하여 더 컸다. 4. 협과 종실의 건물중은 이병성품종의 녹병무발병구에서는 R6생육단계 이후에 급격히 증가하였으나, 녹병발병구에서는 아주 완만하게 증가하였고, 내병성품종에서는 녹병의 영향을 적게 받아 녹병발병구에서 계속 큰 폭으로 증가하였다. 5. 녹병은 불완전립과 빈 꼬투리 수를 증가시키고, 종실의 Oil 함양 및 길이, 폭, 두께를 감소시키며, 협수, 입수, 백립중을 감소시켜 수량을 격감시키지만 단백질 함양에는 영향을 미치지 않았다. 6.수량에 대한 녹병의 영향은 내병성품종에서 22.3%, 이병성품종에서 68.7%의 수양감소가 있었다. The physiological reaction of two soybean (Glycine max (L.) Merrill) cultivars tolerant and susceptible to rust (Phakopsora pachyrhizi Syd.) was studied at the AVRDC in Taiwan, ROC. The rust epidemic on the susceptible cultivar began earlier and progressed more rapidly than on the tolerant cultivar. The defoliation by rust infection increased rapidly after the latter half of pod filling. The reduction of LA! by rust in the susceptible cultivar occurred earlier than in the tolerant cultivar. The differences in the chlorophyll content between the rust-free and rust-infected plants was 2.04% in the tolerant, and 16.43% in the susceptible cultivar. The shoot dry weight increased at each growth stage in the fungicide protected plots, but decreased in the non-fungicide protected plots after the R6 growth stage onward and the tendency to decrease was more severe in the susceptible than in the tolerant cultivar. The pod and seed dry weight of the suscep-tible cultivar in the fungicide-protected plot increased dramatically from the R6 growth stage, but in the non-fungicide plot, there was almost no increase in pod and seed dry weight from R6 growth stage, due to rust. The number of empty pods and imperfect grains were increased by rust infection, but the protein content was not afftected. There were reductions of oil content, seed length, seed width, seed thickness, pod thickness, number of pods and seeds, 100 seed weight, and yield due to rust infection. The yield losses by rust infection were 22.3%in the tolerant and 68.7% in the susceptible cultivar.

A new kidney bean cultivar, “Noghyeob 1” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2005. “Noghyeob 1” was selected from a cross between KLG50074 and KLG50063. It has determinate growth habit, white flower, green pod color, oval shape of crossed section of pod at the harvesting time for edible pod, white seed coat and middle seed size (21.1 grams per 100 seeds). The average yield of edible pod of “Noghyeob 1” was 24.25 M/T per hectare in the yield trials which were carried out at the green house in spring and autumn in 2005. It was 7 percent higher than that of the check cultivar “Kangnangkong 1”.

大豆의 世代短縮에 關한 硏究 Ⅱ. 日長處理가 開花 및 成熟에 미치는 影響

Doo Chull Shin(申斗澈),Hyung Soo Suh(徐亨洙),Soo Kwan Lee(李壽寬) 한국육종학회 1992 한국육종학회지 Vol.24 No.4

For the four times of rapid generation advancement(RGA) of soybean in a year including two times of RGA in the greenhouse during winter, this experiment was conducted to investigate the method of two times of RGA for six months from May to October under different day lengths with natural temperature condition. For this experiment four soybean cultivars, H-25(maturity group, Ⅱ), Ishiharadaizu(Ⅱ), Milyangkong(Ⅲ-Ⅳ), Essex(Ⅴ) were planted on May 1 and August 1 in 1987 in 1/2,000a pots at the Yeongnam Crop Experiment Station(35° 29’ N, 128° 45’ E). And four different day lengths(natural, 12 hour, 10 hour and 8 hour photoperiods) were applied from unifoliate stage to flowering of soybean. The days from planting to flowering(DPF), flowering to maturity(DFM) and planting to maturity(DPM) were shortened effectively at the 10 hours day length at planting on May 1. DFM of Ishiharadaizu was the shortest by 84 days, and it of Essex was the longest by 97 days under 10 hours photoperiod among four cultivars planted on May 1. Also at planting on August 1, DFM of Ishiharadaizu was the shortest by 79 days and it of Milyangkong was the longest by 90 days under 10 hours photoperiod. Under 10 hours day length, the number of grains per plant of four cultivars were ranged from 33 to 59 at planting on May 1, and from 20 to 30 at planting on August 1. These results suggested that two times of generation could be advanced for six months from May 1 to October 31 by applying 10 hours day length from unifoliate to flowering, by harvesting immature soybean seeds before 15 to 20 days of maturity which have germinability over 80 percent.

In Youl Baek(白寅烈),Doo Chull Shin(申斗澈),Hyun Tae Kim(金賢泰),Hyung Soo Suh(徐亨洙),Yong Ho Kwack(郭龍鎬),Yun Jin Oh(吳潤鎭) 한국육종학회 1997 한국육종학회지 Vol.29 No.2

Discovery and transfer of useful characters of wild species into the elite lines may facilitate the development of crop varieties with broad genetic bases. In this study, morphological relationships among fourteen Glycine species was analyzed on basis of twenty-five morphological characters. The upper five principle components contracted from twenty-five morphological characters by the principle component analysis accounted for about 72% of the total variation. The subgenus Soja; G. max, G. gracilis, and G. soja were clearly seperated from the subgenus Glycine; G. arenaria, G. falcata, G. canescens, G. latifolia, G. microphylla, and G. tomentella by the scatter diagrams distributed on the plane of the first and second or the first and third principle components. The cluster analysis and morphological characteristics of G. cyrtoloba and G. curvata were very similar, but they are distinguished from tri-compound leaves at the unifoliate leaf node. Fourteen Glycine species could be classified into eight major groups at the average distance of 0.75 and fourteen sub-groups at the average distance of 0.45, that is, into Group Ⅰ: G. max; Group Ⅱ: A: G. gracilis, B: G. soja; Group Ⅲ: G. microphylla; Group Ⅳ: G. tomentella (2n=38, 40, 78, 80) ; Group Ⅴ: A: G. tabacina (2n=120), B: G. tabacina(2n =40, 80) ; Group Ⅵ: A: G. clandestine, B: G. canescens; Group Ⅶ: A: G. latifolia, B: G. tabacina (2n=40), G. latrobeana, C: G. cyrtoloba, G. curvata; and Group Ⅷ: A: G. falcata, B: G. arenaria.

노동부는 정부에서 인정하는 작업환경측정기관에 대한 측정결과의 정확도와 정밀도를 관리하여 신뢰도와 분석능력을 향상시키고자, 1992년 4월에 작업환경 측정의 정도 관리에 관한 법적 제도를 도입하였다. 정도관리의 시행을 책임진 산업보건 연구원에서는 1992년 5월에 3종의 유기용제와 2종의 금속시료를 가지고 분석능력을 평가하는 기관간 외부 정도 관리를 실시하였다. 제1회의 정도관리에서는 합격율도 저조하였고, 분석결과중 기준값의 0.1배나 2배 이상 등의 오차가 큰 극단값들이 많이 나타났다. 그러나 제2회 및 제3회의 정도관리를 통하여 오차의 크기와 특성을 파악하여 교정하고, 각 기관 자체적으로 오차를 줄이기 위한 노력을 통해 분석능력의 향상을 달성하였다. 제3회까지 정도 관리가 계속됨에 따라 참여율 및 합격율이 크게 향상되었고, 각 분석결과의 오차의 크기도 매우 감소한 것으로 나타났다. 이것은 정도관리제도의 확고한 정착을 의미하며 산업보건연구원에서 실시하고 있는 년 2회의 정도관리는 대상기관의 적극적인 협조아래 매우 성공적으로 실시되고 있고, 작업환경 측정기관의 분석능력과 측정결과의 정확도 및 정밀도를 향상하는 데 크게 기여하였다.
