To screen several promising red pepper cultivars, may be adaptable to organic cultivation conditions, seventy six F1 hybrids commercial and eight local purebred red pepper cultivars were tested. Comparing the infection rate of phytophthora blight between commercial (F1 hybrid) and local (Purebred) cultivars, average infection rate of commercial cultivars was 9.8% and that of local cultivars was 17.8%. But the infected fruits rate of anthracnose in field were similar as 3.3% in commercial (F1 hybrid) and 3.1% in local (Purebred) cultivars. In yield characteristics, average yield of commercial cultivars was 2.89 t $ha^{-1}$ and that of local cultivars was 2.22 t $ha^{-1}$. For organic pepper farmers it is more favourable to cultivation purebred cultivars because they can save to the same quality plant next year's crop. In this study among the local purebred cultivars, two cultivars are promising that their yield near to 3 t $ha^{-1}$ and have disease field resistance.

Recently, the rice growing time was extended by the global warming. This study was conducted to investigate the possibility of rice double cropping system in southern Korea. The first transplanting was with six cultivars ('Kilala397', 'Baekilmi', 'Joun', 'Hanseol' and 'Jungmo1031') on April 15. All cultivars could be harvested at the end of July. Adaptable cultivars for the first cultivation were 'Kilala397', Baekilmi' and 'Joun'. The rice yields at the first cultivation was about 95% of local average yield. Although the yield was slightly less, the first cultivation was considered to have economic benefits, because of the high market price of rice. In the second transplanting was with five cultivars ('Manjong', 'Joun', 'Deabo', 'Jinok' and 'Kilala397') on April 15. All cultivars could be harvested in early November. Adaptable cultivars for the second cultivation were 'Jinok' and 'Kilala397'. The rice yields at the second cultivation was about below the 60% of local average yield, because there was the less growth than normal season cultivation. Consequently, southern Korea' annual rice double cropping system is considered to have no economic value yet. However, the research should be continued considering the temperature rise of global warming.

의성 지역에서 재배하기 적합한 국내 한지형 마늘을 선발하고자 '의성', '예천', '단양', '정선' 및 '용인' 등 한지형 마늘 5종을 공시하여 생육특성과 수량성을 조사하였고, 난지형 마늘의 재배 적합성을 검증하기 위해 '남도' 마늘을 동시에 공시하였다. 국내 지방 재배종 마늘의 생장특성은 생태형에 따라 차이를 보여 난지형인 '남도'가 초기생장과 숙기가 빨랐던 반면, 한지형 지방종간에는 뚜렷한 차이가 없었다. 추대 현상에 있어서는 '정선'과 '용인'이 추대율이 낮았고 불완전 추대가 많았던 반면, '예천'과 '의성'은 추대율이 높고 '의성'은 2차생장률이 낮았다. 의성지방에서 재배된 한지형 마늘 중에 '예천'의 수량이 높았으며 생장 최성기에 타 품종에 비하여 작물생장률도 높았다. 의성 지역에서 재배된 '정선', '용인' 및 '단양'은 '의성'에 비하여 생산성이 낮은 것으로 평가되었다.

Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

Understanding farmer household and community management of crop diversity is necessary in order to effectively strengthen the local plant genetic resources management system in Vietnam, Assessment and management for distribution of farmer's cultivars of rice, taro and tropical tree species were conducted in four different agro-ecological zones in Vietnam using participatory approaches, focus surveys, diversity fairs, agro-morphological field trials, isozyme analysis to understand why Vietnamese farmers grow diverse types of these crop cultivars, when and where these crops cultivars are grown and how farmers maintain and use them. Results showed significant differences in the extent, distribution and use pattern crop cultivars diversity in contrasting environments and between community farmer households. Seed system is an important role in the access and use of diversity in eco-geographical regions.

국내외에서 재배되는 12종의 마늘을 수집하여 총 143개의 임의의 primer를 이용하여 RAPD분석을 실시한 결과 55개의 primer로부터 종간에 다형성을 보이는 DNA밴드가 나타났다. RAPD에 의해 다형성을 보인 55개의 primer에서 확인된 총 DNA 밴드 수는 187개였으며, 그 중 128개(68.5%)가 12종의 마늘 지방종간에 다형성을 나타내었다. PCR에서 다형성을 보인 DNA 밴드를 대상으로 집단분석을 실시한 결과 유전적 유사도가 0.71이상에서 3개의 그룹으로 나누어 졌는데, 제1그룹은 의성, 서산, 삼척, 예천-A, 예천-B종, 의성노랑, 정선, 남도, 단양 및 육백종 등으로 대서종을 제외한 한국의 재배종이 모두 포함되었으며, 제2그룹과 제3그룹은 각각 몽골종과 대서종 단독으로 나누어졌다. 종 특이적으로 DNA밴드를 나타내는 primer를 분석한 결과 21개 primer에서 30개의 DNA밴드가 어느 특정의 지방종에만 나타나는 것으로 확인되어, 지방종 마늘 10종을 구분할 수 있는 30개의 RAPD 마커가 확인되었다.

Panax ginseng has been cultivated for centuries, and nine commercial cultivars have been registered in Korea. However, these nine elite cultivars are grown in less than 10% of ginseng fields, and there is no clear authentication system for each cultivar even though their values are higher than those of local landraces. Here, we have developed 19 microsatellite markers using expressed gene sequences and established an authentication system for all nine cultivars. Five cultivars, 'Chunpoong', 'Sunpoong', 'Gumpoong', 'Sunun', and 'Sunone', can each be identified by one cultivar-unique allele, gm47n-a, gm47n-c, gm104-a, gm184-a (or gm129-a), and gm175-c, respectively. 'Yunpoong' can be identified by the co-appearance of gm47n-b and gm129-c. 'Sunhyang' can be distinguished from the other eight cultivars by the co-appearance of gm47n-b, gm129-b, and gm175-a. The two other cultivars, 'Gopoong' and 'Cheongsun', can be identified by their specific combinations of five marker alleles. This marker set was successfully utilized to identify the cultivars among 70 ginseng individuals and to select true F1 hybrid plants between two cultivars. We further analyzed the homogeneity of each cultivar and phylogenetic relationships among cultivars using these markers. This marker system will be useful to the seed industry and for breeding of ginseng.

Tobacco (Nicotiana tabacum) cultivars including NC 82 and KF 114, and Datura stramonium, Physalis floridana, Gomphrena globosa, and Chenopodium spp. were added to the previous host plants tested for the further examination on the biological characteristics of tobacco mosaic virus (TMV) strains isolated from tobacco (TMV-Common), tomato (TMV-Tomato), and pepper (TMV-Pepper), In TMV-Tomato and TMV-Pepper, different symptoms were noted in P. floridana (no symptom development), and NC 82 (local lesion production on the inoculated leaves) from TMV-Common with which systemic mosaic symptoms were developed. Local lesions were developed in KF 114, D. stramonium, G. globosa, and Chenopodium spp by TMV-Common and TVM-Tomato, while no symptom was observed in KF114 and G. globosa. Also the number and size of local lesions were smaller in KF 114 than Xanthi-nc tobacco (local lesion host) infected with TMV-Tomato. Systemic necrosis was induced in Xanthi-nc and KF 114 when infected with TMV-C at high temperature, but not with the other strains.
