The objective of this study was to obtain informnation about the relationship between seed coat structure and seed vigor in soybean. The seed coat makes up about 6.0 and 10% of seed weight in the soybean. We observed that the hardness seed had the dosed micropyle and high density of wax material embedded in the seed coat, while normal seeds had the opened micropyle and many large pores on the surface of seed coar in soybean surveyed by scanning electron microscopy. Impermeable seed coat retained viability better than permeable seed under delayed harvest field and poor storage conditions. The soybean seed coat consisted of palisade cell layer, hourglass cells and parenchyma. It is believed that, during slow imbibition, the hourglass and parenchyma cell contribute little to the ovrall survival of the seed.

The total land area of Paraguay is 406,752 square km. The country is divided in two major geographical regions, with distinct topography and geology, by the south-flowing Paraguay River. There is a pronounced rainfall gradient right across Paraguay. Mean annual rainfall increases from about 400 mm in the north-west to 1,700 mm in the south-east. In the Chaco, about 80 percent falls in summer, whereas in the south-east comer mean monthly rainfall is more equally distributed, with a slight depression in the driest months, July and August. The growing season lasts from October to March in the Chaco. Typical crops are sorghum, cotton and groundnuts. In eastern Paraguay, arable lands are often cropped twice a year under rainfed conditions, with soybean, cotton or maize, followed by a winter crop, such as temperate cereals. Mean annual temperatures vary from 25.9℃ in the north (Bahia Negra) to 21.4℃ in the north-eastern comer of the oriental region (Pedro Juan Caballero). Summers are hot, even very hot. In winter, night frosts (to an absolute minimum temperature of - 6.0℃) occur, except in the extreme north east. Aerial parts of tropical grasses are generally burnt off by frost. Paraguay is the world` s sixth producer and the fourth largest exporter of soybeans. In the past ten years, the area under soy cultivation more than doubled from 1,870,000 ha in 2004 to 3,500,000 ha in 2014. Paraguay` s major soy producing states are Alto Parana, Itapua and Canindeyu, respectively producing 2,036,618, 1,411,313 and 1,401,086 tonnes soybeans per year. The frontiers of soy expansion are moving towards the center of the country, more precisely in Caazapa, San Pedro and Caaguazu. Agricultural products account for 90% of the value of Paraguayan exports, of which about 57% relates to primary export products such as soy beans, meat and cotton (16.6% of GDP).

A long term soybean breeding project was initiated in the Korea to develop high yielding variety with lodging resistance through the cross semi-dwarf type ``Elf``(Introduced from USA) with Korean leading varieties. It was theorized, however, that additional genetic material might be introduced which would complement the semi-dwarf growth type, combining high yields with lodging resistance. ``Paldal`` is the first semi-dwarf type variety with 53cm plan(height to be released from the National Institute of Crop Science (NICS), RDA, Korea, in 1985. At the same time, ``Paldal`` has been identified to be high yielding variety with 3.18 ton/ha which was higher 41% than check variety, and having the multiple resistance to the most of troublesome soybean diseases. A semi-dwarf variety released in 2002 on the latest is ``Daepung, which is the new variety to be released from twenty year research program directed at developing semi-dwarf soybean varieties. This variety was derived from a cross of ``Baegun`` (a leading variety) with ``Shinpaldal 2`` (a semi-dwarf) in 1992. Regional yield trials for this line, designated as ``Suwon215``, were performed from 2001 to 2002 across nine location. ``Daepung`` is readily distinguishable from other varieties by its semi-dwarf growth habit and its much shorter plant height, approximately 7% that of ``Taekwang``. ``Daepung`` has a determinate growth habit, white flower color, tawny pubescene, yellow testa and light brown hilum color. It is resistant to soybean mosaic virus (SMV) and bacterial pustule, and moderate resistant to the most troublesome soybean diseases. ``Daepung`` has medium seed size (20.7 g per 100 seeds) and also have proper texture and chemical compositions to be suitable for the raw material of the fermented soy-food and the tofu. The average yield on eight locations was 3.05 ton/ha, which was higher by 20% than ``Taekwang``, check variety.

Today, there are becoming a spike in interesting due to development of oversea agriculture in Primorsky Krai, the Russian Far East. Republic of Korea provides an opportunity to attract large investments in this sector of the agriculture of the region. Primorsky Krai is one of the most important agricultural belt in the Russian Far East; the Primorsky krai produces rice, soybean, milk, eggs, and vegetables. The Agro-industrial sector of the Primorsky seems one of the most favorable for such mutually beneficial cooperation. Primorsky Krai, bordered by China, North Korea, and the relatively warm, although freezing in winter, waters of the Sea of Japan, is the most southeastern region of Russia, located between the 42° and 48° north latitude. Highlands dominate the territory of the Primorsky krai. Most of the territory is mountainous, and almost 80% of it is forested. The average elevation is about 500 meters. Average annual temperature - near +1℃ in the north of the Primorsky krai; +5.5 ℃ on the southern coast. Soybean is grown from the Equator to latitude 55° N or 55° S and from below sea level to altitudes close to 2000m. The weather conditions of the area are characterized by large imbalance that causes significant inter-annual fluctuations in crop yield. The spatial and temporal changes in climate and weather elements of Primorsky Krai has an important methodological implications not only for the scientific substantiation of soybean crops allocation in the northernmost parts of the global area of distribution, but also for forecasting soybean yield, the adverse weather conditions risk assessments, recommendations on the use of climatic and prognostic information. Because of the farm tractors and field equipment of Primosky Krai are large and heavy, there is a growing concern about soil compaction. Soil compaction can be associated with a majority of field operations that are often performed when soils are wet in spring season and more susceptible to compaction. Heavy equipment and tillage implements can cause damage to the soil structure. Therefore, Soybean growth become the poor on the compacted soil, and as a result, affect seriously on yield losses. Weeds are a major cause of yield losses in soybean field. Primorsky``s Farmers say it is extremely difficult to control Ambrosia artemisiifolia L., common ragweed, in soybean field. We recommend that in order to effective ragweed control, farmers spray soil applied-herbicide “acetochlor” after soybean seeding, and then have a post-emergence herbicide application (mixed with bentazone and acifluorfen) around 30 days after seeding.

Two F₂ soybean (Glycine max L.) populations, Suwon 157 x Danbaekkong’ and ‘Pureunkong’ x ‘Jinpumkong 2’, were evaluated with restriction fragment length polymorphism (RFLP) markers to construct RFLP genetic linkage maps. For the Suwon 157 and Danbaekkong population, 107 F₂-derived lines were scored for segregation at 97 RFLP loci. Molecular-marker analysis with Mapmaker computer program revealed that the genetic map consisted of 72 RFLP loci which converged into 18 linkage groups and covered more than 600 centimorgan (cM). For the Pureunkong and Jinpumkong 2 population, 100 F₂-derived lines were evaluated for segregation at 92 loci. The genetic linkage map of these 74 loci covered about 700 cM and converged into 20 linkage groups. Two idependent maps were integrated with Joinmap computer package on the basis of 35 RFLP markers which were common to both maps. The integrated map covered about 950 cM with 124 markers classified into 24 linkage groups. As four parental soybean genotypes from both populations have been used to make traditional soybean food products such as tofu, sobean milk, and soybean sprouts, this integrated map will provide useful information on the map position of genes which are associated with special food processing traits in soybean.
