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.
