Soybean [Glycjne max Merr. L.] variety 'Danyeobkong' was inoculated with soybean mosaic virus SMV-G5H strain in field and green house at Crop Experiment Station in 1995. The effects of this virus strain on plant characteristics and seed chemical composition of the soybean variety Danyeobkong were evaluated. Yield, the number of pod and 100 seed weight were significantly reduced by SMV-G5H strain infection. Inoculation of SMV-G5H strain of soybean mosaic virus caused the increment of seed protein content and the decrement of seed oil content in the soybean variety Danyeobkong. Changing pattern of fatty acid composition by SMV-G5H strain infection was varied according to the experimental place. In field trial, the percentage of linoleic and linolenic acids decreased and stearic and oleic acids increased in the seed oil from virus infected plants. In green house trial, however, linolenic and oleic acids were increased, whereas palmitic and linoleic acids were reduced.

This study was conducted to obtain the basic informations for producing high quality seeds of vegetable soybeans. Four vegetable soybean cultivars, 'Okharawase', 'Mikawashima', 'Hwaeomputkong', and 'Seokryangputkong' were planted at four locations, Chulwon(altitude, 192m) and Pyeongchang(altitude, 370m) in highland, and Suwon(altitude, 37m)and Daegu(altitude, 55m) in lowland of Korea with two planting dates, May 15 and June 15. Seed infection rates were attributed by in order of phomopsis seed decay caused by Phomopsis spp., seed mottling caused by soybean mosaic virus (SMV), purple seed stain caused by Cercospora kikuchii. Seed infectron rate was the lowest at Pyeongchang and lower on June 15 than on May 15 planting. Phomopsis seed decay by Phomopsis spp. was lower in highland of Korea, Pyeongchang and Chulwon, than in lowland of Korea, Suwon and Daegu. Seed infection rate was also lower on June 15 planting than on May 15, and in seeds harvested at maturity than at ten days after maturity. Germination rate of seeds harvested in highland, Pyeongchang and Chulwon, after six to seven month storage at 5$\pm$1$^{\circ}C$ was more than 90% and higher than that of the seeds in lowland, Suwon and Daegu. Germination rate was also higher on June 15 than on May 15 planting.
