A soybean cultivar for tofu, ‘Saedanbaek’, was developed from the cross between ‘MD87L’ with high protein content and ‘SS99237 (Pokwangkong/Suwon193)’ with good seed performance and high yield by National Institute of Crop Science (NICS) in 2010. ‘SS99237-45-2-3-1’ was selected by pedigree selection and designated as the name of ‘Milyang 192’. It was prominent and had good result from regional adaptation yield trials (RYT) for three years from 2008 to 2010 and released as the name of ‘Saedanbaek’. It has a determinate growth habit, white flower, grey pubescence, yellow seed coat, spherical seed shape and medium seed (20.7 grams per 100 seeds). ‘Saedanbaek’ has high content in protein (48.2%), and shows excellent result for making tofu. ‘Saedanbaek’ was resistant to bacterial pustule and moderately resistant to soybean mosaic virus, the major soybean diseases in Korea. The average yield of ‘Saedanbaek’ was 2.28 ton per hectare in the regional yield trials carried out for three years from 2008 to 2010.
