  • Burley tobacco (Nicotiana tabacum L.) KB 108 was developed from a single cross between KB 104 and TC 591 which was developed from a cross between Burley 49 and Tobacco Introduction 1406. It was tested for its resistance to black shank, potato virus Y(PVY), TMV and agronomic characteristics under field conditions. KB 108 has resistance to tobacco mosaic virus(TMV) and necrotic strain of potato virus Y(PVY-VN) with secreting glandular trichomes. It has also moderate resistance to black shank caused by phytophthora parasitica val. Nicotianae. KB 108 has an up-right plant growth habit similar to Burley 21. It flowers about 1-2 days later than Burley 21. The leaf width and length of KB 108 are approximately 3 cm wider and longer than those of Burley 21. The yield of KB 108 was higher 4%, nearly equal in value per kg compared to Burley 21.

  • This study was conducted to find out some important agronomic characteristics and qualities in response to different transplanting dates in Alisma plantago at southern parts of Korea. Yield components such as number of floral axis per plant, plant height and number of leaves were highest at the transplanting date of Aug. 15 and Aug. 25. Plants sown at Aug. 15 and Aug. 25 also showed highest yield. Considering from our results, optimum transplanting date were semed to be transplanting date of Aug. 15 and Aug. 25.

  • 본 실험은 고품질 다수성 생강 품종육성에 필요한 기초 자료를 얻기위해 국내에서 수집한 우량생강 24클론을 포장과 하우스에서 재배하여 주요 작물학적 특성을 조사한 결과 다음과 같다. 조사된 클론중에서 수량과 6-gingerol 함량에서 높은 유의차가 인정되었다. 포장에서는 CG9579(3520kg/10a)의 수량이 가장 높았고, 그 다음으로 CG95134, CG9512, CG96109, CG9596 순이었다. 우량 클론으로 선발된 클론중 6-gingerol 함량을 조사한 결과 CG9579가 4.44mg/g로 가장 높았으며, 그 다음으로는 CG9583이 4.35mg/g, CG95134가 4.32mg/g순이었다. 하우스에서 는 수량이 CG9503과 CG9521 클론이 10a당 5529kg으로 가장 높았고, CG9515, CG9578, CG9579, CG96103 그리고 CG95105 클론이 10a당 4,000kg이상의 수량을 보았다.

  • These studies were conducted to provide basic information on Korean ginseng cultivars and breeding lines (Panax ginseng C. A. Mey.) and to identify the variations that can be utilized in ginseng breeding programs. The agronomic characteristics was used to clarify the genetic relationships among Korean ginseng cultivars and breeding lines and to classify them into distinct genetic groups. Angle of petiole and number of fibrous root showed a wide variation from $15.0{\sim}67.8^{\circ}$ and 0~5, respectively. The average plant length was 54.2cm with a range of 37.9~64.8cm and the average stem diameter was 5.6mm with a range of 4.0~7.5mm. The average stem length was 31.9cm with a range of 21.8~37.9cm and the average root weight was 38.1 g with a range of 23.0~52.0 g. The 24 Korean ginseng cultivars and breeding lines were classified into 4 groups based on agronomic characteristics using the complete linkage cluster analysis. The I, II, III and IV groups included the 60.8%, 7.4%, 13.1% and 8.7% of the cultivars and breeding lines, respectively. The breeding lines in group I could be characterized as the group with the highest growth characters and yield components, such as plant length, stem diameter and root weight. The root weight, the yield component, had highly significant positive correlations with stem diameter, plant length and stem length.
