KB 101 is a bacterial wilt(Pseudomonas solanaceamm E.F. Smith) and black shank (Phytophthora nicotianae Breda de Haan Var. nicotianae Waterhouse) resistant cultivar of burley tobacco (Nicotiana tabacum L.) KB 101 was developed by the Korea Ginseng&Tobacco Research Institute, and released in 1987. KB 101 was developed from a single plant selection in the F2 generation derived from the double cross, [(Burley 21X Burley 37) X (Burley 64X Ky 16)]. Burley 37 and Burley 64 were the source of resistance to bacterial wilt and black shank. Yield trials were conducted in the Fs through F6 generations at the four Exp. Stn. of Korea Ginseng &Tobacco Research Institute as JB 7705-1. On-farm yield trials were conducted in the F7 through F9 generations at the 45 locations of burley tobacco growing area from 1984 to 1986 as KB 101. KB 101 has an erect growth habit similar to that of Burley 21: plant size is larger and has more leaves than those of Burley 21. It is late maturing cultivar that flowers approximately 3 days later than Burley 21. The physical characteristics and chemical composition of KB 101 were similar to those of Burley 21.
One of the most common communication mechanisms to describe a situation or a process is a story written as an ordered sequence of events or activities. For example, a shop floor supervisor may present the operations of his manufacturing system by describing the processes of manufacturing a product in his shop. Although IDEF3 is one of the most commonly used methods for describing a business process, but it is not common for a manufacturing process. In this study, we tried to apply IDEF3 for describing a manufacturing process. Problems and suggestions such as selection probability, programmable process modeling, manufacturing resource model were presented.
Three levels of nitrogen, phosphate and potassium were applied to tobacco for the establishment of the optimum rate of the fertilizers for yield and quality. 1 . The rate increment of nitrogen and potassium increased tobacco growth, but phosphate were non - significant between rate. 2. The contents of total-nitrogen and total-alkaloid in the leaf were increased, with the increase of nitrogen rate while the effect of phosphate and potassium were negligible. 3. The yield and quality of the tobacco were increased with the increasing rate of nitrogen and potassium fertilizer but phosphate should little difference.
심경과 多肥栽培가 버어리種 담배의 收量 및 品質에 미치는 영향을 구명하고자 耕土깊이를 10,20,30cm로 하고 施肥水準을 標準施肥(138kg/10a), 20%增肥, 40%增肥로 하여 3년간(1976-1978) 實驗한 결과 收量 및 品質 공히 심경 다비할수록 증가하여 수량은 耕土깊이 30cm 구에서 5%, 40%增肥區에서 13%가 증가하였으며 품질은 심경과 다비로 각각 2%씩 증가하였다. This experiment was carried out determine the effect of plowing depth and heavy fertilization on the yield and quality of Burley tobacco. In the experiment, three plowing depth (10, 20, 30cm) and three levels of compound fertilizer (138, 166, 193kg/10a) were employed with split plot design for three years (1976-1978). Yield and quality were increased with deeper plowing and heavier fertilization. Yield was increased by 5% at the plowing depth of 30cm and 13% at the fertilizing level, 193kg/10a. The value per kg was increased by 2% plowing depth of 30cm and at the fertilization of 193kg/10a, respectively.
Black shank(Phytophthora parasitira roar. nicotianae) resistant burley tobacco (Nicotiana tabacum L.) germplasms, KB 104 and KB 106, were developed by Korea Ginseng & Tobacco Research Institute. KB 104 was developed from the single cross of Burley 21$\times$Newton 77, using a modified pedigree method. KB 104 was highly resistant to black shank, and its agronomic characteristics and chemical contents were comparable to those of Burley 21, and value per 10a was slightly higher than Burley 21, KB 106 is a maternally derived doubled haploid made by N. africana method from the single cross of Burley 21$\times$ Va 509. KB 106 was also highly resistant to black shank, had two more harvestable leaves per plant and flowered three days later than Burley 21 did. Total alkaloid and nicotine contents of KB 106 were significantly lower than those of Burley 21. But its nornicotine content was higher than Burley 21 5. Key wads : Burley tobacco germplasm, Black shank resistance.
