Abstract
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
