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.

To obtained the basic information needed in the development of higher quality and yield of ginger, twenty-four indigenous colones of ginger were evaluated major agronomic characteristics under field and polyethylene house culture. There was highly significant differences in yield and 6-gingerol contents among the clones studied. Maximum yield was recorded in clone CG9579(3520kg/10a) followed by CG95134, CG9512, CG96109, CG9596, in field culture. The maximum 6-gingerol percentage was recorded in the clone CG9579 containing 4.44mg/g, and next was CG9583 4.35mg/g, CG95134 4.32mg/g DW. In addition, CG9503 and CG95105 clones showed more than 4,000kg/10a in polyethylene house culture.

The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. This experiment was carried out to select pure-line from the domestic black soybean genotypes, and survey some agronomic characteristics of the collections. Nine hundred and sixty five lines of black soybeans were collected in 197 locations on spring, 1991. Higher distribution was present in broad leaves, purple flower color and tawny pubescence color which were approximate to be 97, 90 and 98%, respectively. In pod color of black soybean collections, 60% was brown and 27% was light brown and 10% was dark brown. The 61 to 70 days were required for flowering in 61 % of the collections. Growing days of 51 % of black soybean collections ranged 121 to 130, and those of 37 % were over 131 days.

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.
