This study was carried out to select superior soybean cultivars for forage production for soybean forage production in Jeju. The results obtained are summarized as follows; Eighteen soybean cultivars were grown from May 11 to September 11 in 2002 in Jeju to select superior cultivars for forage production. Days to flowering was shortest(58 days) for Seokryangkong and Keunolkong, and longest(93 days) for Danpaheukdu. Days to flowering for other cultivars ranged from 65 to 69 days. Pureunkong and Namhaekong had greater heights(129.3 and 124.6 cm, respectively) while Keunolkong, Hwaeomkong and Seokryangkong had shorter heights. The number of branches per plant was gratest for Sobaekkong, Manrikong, Pungsankong, Kwangankong and Geumgangkong. The number of leaves per plant was geatest for Sobaekkong, Iksankong and Namhaekong. Rueunkong and Jangmikong had thicker stems. Fresh forage yield was greatest for Iksankong, Sobaekkong and Namhaekong(39.5, 39.3 md 38.0 MT/ha respectively). DM yield of forage was featest for Baekunkong, Hnrunkong and Danpaheukdu. Danwonkong, Dawonkong, Seokryanfong and Pungsankong had ueatest forage crude protein content. Duyukong and Kwangankong had featest forage crude fiber content. Jangmikong and Keunolkong had feater crude fat content, while Sobaekkong and Kwangankong had greater crude ash content. Namhaekong, Seokryangkong, Keunolkong and Jinpumkong had greater NFE contents ranging 40.0 to 43.5 and TDN was featest in Keunolkong, Danpaheukdu, Namhaekong and Seokryangkong had greater NFE contents ranging from 59.8 to 60.9％. The best cultivars in Jeju for forage soybean appear to be Namhaekong, Danpaheukdu md Baehukong on the basis of crude protein, TDN, and dry matter yields.

We carried out the experiment to select the suitable sprout soybean varieties for environment-friendly cultivation in paddy field of southern part area, compares of excess moisture injury degree and yield ability among 29 sprout soybean varieties. Plant growth of sprout soybean was generally low in beginning and recovered after flowering due to rainfall. In paddy field cultivation, number of pod per individual and number of seed per individual were less in difference than upland cultivation, and maturing date was delayed 5-14 days than upland cultivation in most species. When environment-friendly cultivation, pest injury was not caused major problem for the growth during the vegetative period of soybean due to ground spider as natural enemy to insect pest. However, damage of stink bugs showed severe during grain filling period, and Dawonkong, Anpyeongkong, Dachaekong and Wonhwangkong showed susceptible to sting bug. SMV infection was weak and showed some necrosis symptoms in Sokangkong, but black root rot was not infected at all. Bacterial pustule began to be infected slowly from pod enlargement stage in most species, displayed severe symptoms in Dawonkong, Pungsannamulkong, Seonamkong and Sobaeknamulkong. The symptoms of pod anthracnose, pod blight and purple spot were greatly appeared after flowering. Disease resistance varieties was Paldokong, Kwangankong, Doremikong, Somyeongkong, Pungsannamulkong, Iksa-namulkong, Seonamkong, Sojinkong, Pureunkong, Bosugkong, Namhaekong and Sorokkong. Lodging index showed 3 in Saebyeolkong, and other species displayed slight lodging in 0-3 degree. 100-seed weight is 9.8-17.2g extent and increased 0.1-3.7g than upland cultivation in most species, but decreased in some species. Government purchase standard, species correspond to small-seed-size namulkong (Sizing screen diameter 4.0-5.6 mm) was Dawonkong, Dachaekong, Bosugkong, Seonamkong, Sokangkong, Hannamkong, Somyeongkong and Wonhwangkong. Species which seed yield was higher than Pungsannamulkong (266kg/10a) were Sorokkong, Hannamkong, Bosugkong and Sowonkong. Considering sprout soybean species, disease endurance, insect resistance, lodging resistance, 100-seed weight, yield ability and excess moisture tolerances synthetically, Seonamkong, Hannamkong, Doremikong, Bosugkong, Pungwonkong, Kwangankong, Sowonkong, Dagikong, Paldokong, Eunhakong and Pungsannamulkong were promising for environment-friendly cultivation in paddy field.

The allergenicity of soybeans was analyzed using polyclonal antibodies and the blood sera of patients with soybean allergy, using fourteen different varieties of soybeans that are consumed in Korea. The study that used polyclonal antibodies having specificity for soybeans showed that while some of the fourteen varieties of soybeans contained additional protein bands indicating antigenicity, others lacked such bands, and the most antigenic protein was found in Jinpum soybeans. In comparing blood sera reactivity of four patients having soybean allergies, who had antigenicity values of 65U/ml or more according to CAP testing, the soybean varieties of Danbaek and Shinpaldal2 had the most reactivity and Daewon had the least. The result that the allergenicity of proteins in soybeans differs according to the variety of soybean, leads to the conclusion that it may be possible to reduce consumer allergic reactions to soybean products by choosing an appropriate variety of soybeans.

A total of 75 soybean cultivars developed in Korea was screened against soybean cyst nematode (SCN), Heterodera glycines HG type 2.5. Cysts developed on soybean cultivars ranged from 104 to 624 cysts per pot. There was no resistant cultivar but 'Jangyeopkong', 'Saealkong', 'Miryangkong', and 'Mansukong' were moderately resistant; 33 cultivars were moderately susceptible and the other cultivars were susceptible. 'Jangyeopkong', 'Saealkong', 'Miryangkong', and 'Mansukong' could be recommended for soybean fields infested with SCN until developing SCN resistant soybean.

Self-and reciprocal-graftings were made between soybean varieties(cv.Hwangkeumkong, Paldalkong, Bokwangkong and Jangkyongkong) to assertain the relative role of shoot and root in soybean growth and yield determination. The influence of grafting per se on plant height and leaf number on main stem were negligible as evidenced by the insignificant differences between self-and reciprocal-graftings. The effect of grafting on flowering was different between different set of varieties grafted reciprocally. Self grafting delayed flowering 2 days and reciprocal grafting delayed another 2 days, in general. The effects of grafting on dry weights of different plant parts except pod were also insignificant. Reciprocal grafting increased pod dry weight in Hwangkeumkong and Paldalkong regardless whether they were used as scion or stock. Reciporcal grafting also influenced dry weights of Bokwangkong and Jangkyongkong significantly, but the response was different from those of Hwangkeumkong or Paldalkong. Jangkyongkong, when used as stock, decreased total dry weight of Bokwangkong significantly through the reduction of pod and stem dry weights. Stem diameter was increased by grafting, however, grafting decreased number of branches in all varieties. The average yields of self-and reciprocal-grafting were decreased by 11% and 24%, respectively, comparing to that of non-grafting, while average yield of reciprocal grafting was 14% lower than that of self grafting. Stem weight of grafted soybeans was decreased by 29-32% comparing to that of non-grafted soybeans, but the difference between self and reciprocal graftings was negligible. The genetic characteristics of scion was found to be more important than those of stock in determination of yield and stem weight. It was also indicated that varieties and characteristics are different in response to grafting.

Seven varieties of soybeans (Paldal, Danyeob, Jangbaek, Baegun, Jangyeobkong and 2 cultivars of Local 1 and Local 2) were investigated to compare the germination properties and cooking rate. The growth rate of soybean sprout roots was slower for larger size of soybeans. A 100% of germination was obtained for Danyeobkong and Paldalkong. Local 1 and Local 2 were lowest, 47% and 31%, respectively in germination ratio. The hardness of cooked soybeans measured by the maximum cutting force of cotyledon showed that Local 2 was softer and Danyeobkong was harder than other varieties.

Microsatellites are one of the most suitable markers for identification of variety, as they have the capability to discriminate between narrow genetic variations. The polymorphism level between 120 microsatellite primer pairs and 148 soybean varieties was investigated through the fluorescence based automatic detection system. A set of 16 primer pairs showed highly reproducible polymorphism in these varieties. A total of 204 alleles were detected using the 16 microsatellite markers. The number of alleles per locus ranged from 6 to 28, with an average of 12.75 alleles per locus. The average polymorphism information content (PIC) was 0.86, ranging from 0.75 to 0.95. The unweighted pair group method using the arithmetic averages (UPGMA) cluster analysis for 148 varieties were divided into five distinctive groups, reflecting the varietal types and pedigree information. All the varieties were perfectly discriminated by marker genotypes. These markers may be useful to complement a morphological assessment of candidate varieties in the DUS (distinctness, uniformity and stability) test, intervening of seed disputes relating to variety authentication, and testing of genetic purity in soybean varieties.

In order to obtain fundamental information for developing new salinity tolerance soybean cultivars, the germination rate was evalulated with a total of 28 soybean varieties. The germination rate of soybean cultivars was decreased as the NaCl concentration was higher and that by temperature difference was the lowest at 35$^{\circ}C$. the germination rate of 1.2% NaCl treatment of seed shape and size was the highest at 15$^{\circ}C$ but was the lowest at 35$^{\circ}C$ in small seed groups. The germination rates of Gumjungkong, Alchankong, Gumgangkong, Hayumkong, Hwasungpukong, Janmikong cultivars were higher when treated with 1.2% NaCl at 35$^{\circ}C$, but those of Dawonkong, Hannamkong, Kwangankong, Daebaekkong, Danwonkong, Sukwyangputkong, Keunolkong, Bokwangkong, Jangyoupkong cultivars were lower. The germination rate of soybean cultivars was significantly decreased by higher temperature and NaCl concentration.
