As a result of research efforts to produce more higher yielding variety with the adaptative ability to higher plant density, a new soybean variety named Kyung Nam No.3 was developed. It was produced through the pedigree method and the cross of Ulsan (Korean local variety) and Tamaoki Wase (Japanese variety) was conducted at Chinju National Agricultural College in 1963. 113.6% of higher yielding ability was recorded compared with the control variety, Kyung-Nam No.1, under various conditions for plant density in yield trial. It was also recognized that this variety showed the good result for many environmental conditions as an adaptative variety in Finlay’s adaptation test.

張權烈,韓鏡秀,高美錫,崔震龍 慶尙大學校 1972 論文集 Vol.11 No.-

以上의 結果를 要約하면 아래와 같다. 1. 雜草發生率은 品種間에는 有意性이 없으며 약제간에는 Mon가 7%, Lark 31%, MA 32%로서 Mon가 雜草發生이 제일 낮았다. 2. 雜草重은 品種間에는 有意性이 없으며 약제간에는 Mon 12.5kg, LA 13.7kg, MA 15kg로서 Mon가 제일 적었다. 3. 除草劑의 처리에 의한 種實重量은 관행구에 비하여 Mon은 56.8%, MA는 55.9%가 감소 되었고 LA는 가장 낮은 46.7%가 감소 되었다. 4. 經濟性 分析의 結果 10a當 순수익으로 LA 3,463원 MA 2,736원 Mon 2,641원으로서 관행구의 868원에 비하여 除草劑의 처리에 의하여 순수익을 높일 수 있었으므로 除草劑의 導入이 時急하다. The objective of this study was to evaluate the three herbicides, Machete, Mon-097 EC, and Lasso for annual weed control in soybeans at the experimental farm of Gyeong-Sang College. The results were summarized as follows; 1. The ratio of weed was not shown significance among the varietieties, as shown Tables 1 and 2, but the significance was shown among the herbicides and the plot of Mon-097 herbicide showed lowest value, 7%, as shown in Table 1. 2. The weight of weed also was not shown the significance among the varieties but the significance was shown among the herbicides, such as shown in Tables 1 and 2. The weight of weed also showed the same tendency as the ratio of weeds. 3. The yields of treated soybeans showed lower yield than normal condition plot, such as Mon-51.8%, Ma-55.9%, La-46.7%, respectively. 4. According to the analysis of economic values, herbicide plots were got more net-income than normal condition plot. It is needless to say that herbicides had to be recommendable in this case.

In order to investigate the effects of grazing and fertilization on the improvement of oversown pasture on the hill country, an experimental site was selected from the northern aspect of Namwon Branch of the National Animal Breeding Institute. Each plot, sized 15㎡, was fenced and native vegetations were grazed by nine sheep for three days to reduce the density of native vegetation and to open space for introduced pasture. Before sowing, lime(1.5t per ha) and phosphorus(690g per plot as super phosphate) were fertilized. Selected cultivars of Dactylis glomerata, Festuca arundinacea, Trifolium repens and Trifolium pratense were sown at the rates of 3.4kg seeds for grasses and 0.6kg for legumes per 180㎡. Legume seeds were inoculated before sowing. After germination, the grazing plot were grazed by sheep with 20 to 30 day-intervals. Herbage yield and botanical composition were measured with one-month interval after wintering. Herbage yield increased significantly in the grazed plots and the yield was doubled by fertilization. The yield of fertilized plots without grazing was comparative to that of grazed plots without fertilization. There was a significant improvement in the botanical composition, i. e. , 20 per cent grasses before improvement turned out 86 per cent introduced grasses at the end of three years from sowing on both grazed and fertilized plots. However, the improvement was retarded up to 35 per cent in the stated plots without fertilization. The initial 7 per cent of legumes increased up to 50 per cent in the grazed and fertilized plots, which is not comparable to 15μ per cent for grazed without fertilization. High proportion of native shrubs(73 per cent) rapidly decreased up to 2.3 per cent after three years from sowing. Conclusively, it was envisaged that the introduced pasture plants showed better response to grazing and fertilization, and that the hill land can be .improved effectively by fencing, fertilization and regular grazing immediately after seed germination.

崔震龍,金正敎,許文會 慶尙大學校 1976 論文集 Vol.15 No.-

쌀의 amylose 含量이 栽培環境 特히 P·K 肥料와 栽培時期에 따라서 어떻게 變異하는가를 究明하기 爲해서 P·K 를 0.12, 24kg/10a의 3水準으로 하고 N를 12kg/10a로 固定시킨 후, 栽培時期를 普通期와 晩期로 區分하고, 6個 品種/系統을 使用하여 행한 試驗에서 얻은 結果를 要約하면 다음과 같다. 1. 쌀 amylose含量 P·K 肥料에 따라서 各品種의 反應에는 一定한 傾向을 發見할 수 없었다. 2. 쌀 amylose含量은 P·K 肥料處理에 依하여 有意的인 變異를 나타내지 못하였다. 3. 晩期栽培한 벼는 普通期裁培한 벼에 비하여 쌀 amylose含量이 增加하였다. In order to find out the effect of P and K ferilizers and cultivating seasons onthe variability of amylose aontent in rice(Oryza sativa L.) 9 treatment composed of teh combination of three levelsof phosphorous and potassium ferilizers at the fixed nitrogen level were made in two cultivating seasons, ordinary and late, with six varieties/lines. The results obtained are summarized as follows: 1. Any tendency was not found among the responses of amylose content of varieties/lines to P·K fertilizations. 2. Amylose content of rice grain was not significantly variated by P.K treatments. 3. Late season cultture showed higher amlylose content than ordinary one.

The Inheritance of Amylose Content and Alkali Digestibility Value of Rice (Oryza sativa L.)Applied as "Waxy Carrier Technique"

CHOE,Zhin Ryong,HEU,Mun Hue,LEE,Eun Woong 서울大學校 農科大學 1977 서울대농학연구지 Vol.2 No.1

본 硏究는 (1) 米質 特히 食味와 관계되는 두가지 主要形質인 amylose含量과 알칼리崩壞度(ADV)에 미치는 環境의 影響을 空明하고 (2) 새로이 提唱된 waxy carrier technique理論에 根據하여 쌀벼와 메벼의 交雜에서 나온 메벼가 이들 形質을 母本으로부터 어떻게 傳授 받는가를 밝히고 (3)이 理論을 應用하여 含量이 다른 두 메 品種의 F₁을 찰벼와 戾交雜하고 거기서 나온 순수 메벼의 amylose含量의 分離比를 검토하여 쌀 amylose含量의 遺傅에 관한 情報를 얻기 위한 目的으로 實施되었다. 쌀 amylose 함량 및 알칼리 崩壞度에 미치는 환경,特히 溫度의 영향을 空明하기 위하여 인공기상실에서 진흥, 유신 및 IR-30의 3品種을 出穗期에서 5 혹은 10일간 또 蒸發器에 7일간 15℃ 혹은 30℃에 처리한 것을 自然條件에서 栽培한 것과 비교하였고(試驗 I), 밀양 23호(메벼)와 Wx 317-4-7-4(찰벼)의 交雜에서 나온 F₂개체의 出穗期를 精密히 조사하고 homozygous nonwaxy F₂와 waxy F₂를 분리하여 그 종자를 여러 濃度의 KOH용액에서 알칼리 崩壞度를 검정하고 出穗期와 알칼리 崩壞度 간의 관계를 空明하였다.(試驗 II). Waxy carrier technique에 근거하여 쌀의 amylose 함량 및 알칼리 崩壞度가 母本으로부터 雜種世代에 移轉하는 원리를 空明하기 위하여 두 찰벼(Wx 316-9-10-1-2와 Wx 199-33-6-1-3)를 amylose 함량과 ADV가 相異한 4가지 메벼와 交雜하고 거기서 나온 찰메에 대하여 homozygous인 F₂개체중에서 amylose含量을 메벼에 한하여, 알칼리 崩壞度를 메와 찰을 같이 사용하여 檢定하였다(試驗 Ⅲ). 또 waxy carrier technique 理論을 應用하여 쌀 amylose 含量의 遺傅에 관한 정보를 얻기 爲하여 amylose含量이 다르고 標識形質(marker character)을 가진 8개 isogenic line을 交雜하고 이들F1을 所謂 短桿찰계통(semi-dwarf waxy line)에 戾交雜, 그 後代에서 나온 메벼의 amylose 含量을 分析하여 그 分離상태를 검토하였다(試驗 Ⅳ). 以上의 4가지 試驗에서 얻은 結果를 要約하면 다음과 같다. (1) 出穗期에 5日 혹은 10日간 30℃에 처리하였을 때 amylose 含量은 有意的인 變化가 없었으나 알칼리 붕괴도는 有意的으로 減少하였다. 같은 時期와 기간동안 15℃에 처리하였을 때에는 自然상태의 것과 비교할 때 amylose 함량이나 ADV에서 有意的인 差異가 認定되지 않았다. (2) 알칼리 붕괴도는 밀양 23호와 Wx 317의 교잡에서 나온 homozygous nonwaxy F₂개체 혹은 메 母本의 경우에는 1.5%, homozygous waxy F₂개체 혹은 찰 母本의 경우는 1.6% KOH濃度에서 각각을 檢定암이 妥當하였고, 出穗期와 알칼리 崩壞度 間에는 有意的인 正의 相關이 認定되었다. (3) 메나 찰의 交雜에서 나온 homozygous 메 F₂개체의 amylose含量은 메母本의 amylose함량과 같은 정도로 回復되었으나 알칼리 崩壞度는 메와 찰에서 매우 큰 變異를 나타내었다. 그러나 育種的인 見地에서 母本의 알칼리 崩壞度를 回復할 수 있는 個體의 選拔이 可能할 것으로 보였다. (4) Amylose함량이 다른 isogenic line을 상호 交雜하고 이 F₁을 몇가지 찰과 檢定交配하여 여기서 나온 雜種後期世代에서 分離한 메벼의 amylose함량을 分析한 결과 모든 供試組合에서 1 : 1 로 分離하는 二頂分布(bimodal distribution)를 나타냄으로써 쌀 amylose含量은 한쌍의 單純遺傳子에 으하여 支配된다는 것을 確認하였다. The main purpose of this study was (1) to determine the envirnmental influence on two major quality charcters related to cooking and eating qualities of rice, i.e., amylose content and alkali digestibility values(ADV), and (2) to evaluate the genetical behavior of these characters by applying the waxy carrier technique. For the study on the environmental influence on these characters, three varieties, Jinheung, Yushin and IR-30, were tested in the different temperatural conditions at maturation, and the relationship berween the heading date and ADV was estimated in the cross between Milyang 23 and Wx317-4-7-4. For the study on the transmittance of amylose content and ADV based on the waxy carrier technique, ADV-different two waxy lines, and four near-isogenic nonwaxy lines were used. And finally to evaluate the genetical behavior of amylose-different eight issogenic lines with typical base color s a marker were used as amylose parents. The results obtained from these four experiments are summarized as follows: (1) When the rice plants were placed in 30℃ for 5 of 10 days at heading, the samples did not show any significant changes in amylose content but showed significant changes in ADV. And when the plants were placed at the same temperature for 7 days at ripening stage, the samples showed significantly low amylose content and low ADV. Amylose content of samples tested in 15℃ for the same periods showed no significant difference compared to those in the natural condition. (2) In a cross between Milyang 23 and Wx317, F₂plants with homozygous nonwaxy endosperm and nonwaxy parent showed significant postive correlation between heading date and ADV in 1.5% KOH at 30℃, while F₂plants with homozygous waxy endosperms and waxy parent showed such positive correlation in 1.6% KOH at 30℃. (3) In the crosses between nonwaxy and waxy parents, the amylose content of nonwaxy parents was transmitted to the F₂plant whith homozygous nonwaxy endosperms, which is coincident with the principle of waxy carrier technique. However, ADV was not so simple to apply the waxy carrier technique due to the large variation in ADV of homozygous F₂plants. (4) When F₁lines derived from the nonwaxy amylose-different parents were testcrossed to waxy lines, the isolated homozygous nonwaxy plants showed segregation of 1 : 1 in amylose content, showing bimodal distributions in all combinations tested. This result confirmed that the amylose content in ricd is controlled by one pair of major genes.

Developement of hybrid-seed production system in self-pollinated crops by chemical-induced male sterility

CHOE, ZHIN RYONG,YANG, MIN SUK,KIM, SEOK HYEON,OH, HO SANG 경상대학교 유전공학연구소 1988 遺傳工學硏究所報 Vol.7 No.-

In order to investigate the effects of chemicals on electrophoretic properties of leaf protein, rice seedling(cv. Dongjin) at 4-leaf stage was foliar-applicated by four chemcials and a relationship between the effect of chemicals on the alteration in banding proteins was examined. Among the chemicals 2000ppm(a. i.) sodium arsenite caused an alteration in banding proteins(MW 45000), but the alteration was proved not to coincide with grain sterility of outcross rates. The same chemicals were foliar applicated to female parents of wheat and barley at a late-booting stage, which were grown under the different distance and orientation from pollinators. Grain sterility and outcross rate were investigated by the enveloping method. The effects of orientation of pollinators adn cross direction on grain sterility or outcross rates were inconsistant in different cross combinations. However, the distance of poollinators proved to be great importance in hybrid-seed production in self-pollinated crops.
