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.

A soybean cultivar for sprout, ‘Joyang 1’ was developed at the National Institute of Crop Science (NICS) in 2010. ‘Joyang 1’ (Iksan67) was released by pedigree selection from the cross between high yielding ‘Pungsannamulkong’ and ‘Suwon187’ tolerant to lodging and disease. It has purple flower, lanceolate leaf, grey pubescence and small yellow seed. Weight of hundred seed is 11.6gram. Maturing date of ‘Joyang 1’ is ten days earlier than check cultivar, ‘Pungsannamulkong’. ‘Joyang 1’ is resistant to bacterial pustule and shattering. It have similar tolerance to root rot and seed spot to check cultivar. It shows high germination ratio, less abnormal germination and hard seed. Sprout yield also 11 percent higher than check cultivar. The average seed yield of ‘Joyang 1’ was 3.03 ton per hectare in the regional yield trials (RYT) carried out for three years from 2008 to 2010 which was 3 percent higher than the check cultivar. The number of breeder’s right is ‘4900’.
