To select the desirable soybean cultivar for chonggugjang processing, the physicochemical characteristics of raw soybean materials and chonggugjang samples were investigated. Eight soybean varieties including Danyeobkong, Danbaegkong, Kwanankong, Pureunkong, Manlikong, Sinpaldalkong 2, Jinpeumkong and Hwankeumkong were used for experiment. On the basis of quality characteristics of raw materials, such as seed coat weight rate, hydration swelling, and the content of fructose, glucose and sucrose, and chonggugjang, such as hardness, ${\gamma}-glutamyltranspeptidase\;({\gamma}-GTP)$ activity, free amino acid content, and amino type nitrogen content, Sinpaldakong 2 and Danyeobkong were desirable soybean cultivars for high quality chonggugjang processing.
