The soybean cultivar, ‘Saegeum’, has been developed for preparing soy-paste and tofu. The soybean cultivars ‘Daepung’ and ‘SS98207-3SSD-168’ were crossed in 2003 to obtain ‘Saegeum’. Single seed descent method was used to advance the generation from F₃ to F₅, and the plant lines with promising traits were selected from F₆ to F₇ by pedigree method. The preliminary yield (PYT) and advanced yield trials (AYT) were conducted from 2009 to 2010, and the regional yield trial (RYT) was conducted in 12 regions between 2011 and 2013. The morphological characteristics of ‘Saegeum’ were as follows: determinate plant type, white flower, tawny pubescence color, and brown pod color. Flowering and maturity dates were August 2, XXXX and October 17, XXXX, respectively. Plant height, first pod height, number of nodes, number of branches, and number of pods were 79 cm, 18 cm, 16, 2.3, and 44, respectively. The seed characteristics of ‘Saegeum’ were as follows: yellow spherical shape, yellow hilum, and the 100-seed weight was 25.4 g. ‘Saegeum’ was resistant to bacterial pustule and SMV in the field test, and its lodging resistance was mildly strong, whereas its shattering resistance was excellent. The ability of this cultivar to be processed into tofu, soybean malt, and other fermented products was comparable with that of ‘Daewonkong’. The yield of ‘Saegeum’ in the adaptable regions was 3.02 ton ha^-1. Thus, ‘Saegeum’ is adaptable to mechanized harvesting because of its high first pod height, as well as lodging and shattering resistance. (Registration number: 5929)

A soybean cultivar “Chamol” for double cropping for use as soy-paste and tofu was developed using a pedigree method in 2011 as a cross between “Shinpaldal2” and “Keunol.” A promising line, SS99502-2B-89-1-3-4-1-1, was selected and designated as “Milyang210”. It was promising and showed good results from regional yield trials (RYTs) for 3 years from 2009 to 2011 and released with the name “Chamol.” It has a determinate growth habit, white flowers, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape, and large seeds (27.7 g per 100 seeds). The maturity date of “Chamol” was September 18 (100 day growing period) in RYT and it is suitable for double cropping with winter crops such as onion. “Chamol” was resistant to bacterial pustule and soybean mosaic virus and tolerant to lodging in fields. Furthermore, the average yield of “Chamol” was 2.51 ton/ha in the regional yield trials conducted for 3 years from 2009 to 2011.

A soybean cultivar for soy-paste, ‘Hwangkeumol’, was developed from the cross between SS92414 (crossing line of ‘Pokwangkong’ and ‘Suwon163’) and ‘Hwaeomputkong’ by soybean breeding team in the National Institute of Crop Science (NICS) in 2010. A promising line, SS99409-2B-11-5-4, was selected and designated as the name of ‘Milyang202’. It was prominent and had good result from regional adaptation yield trials for three years from 2008 to 2010 and released as the name of ‘Hwangkeumol’. It has a determinate growth habit, white flower, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape and large seed (28.6 grams per 100 seeds). Maturity date of ‘Hwangkeumol’ was as early as September 15th. Therefore it is suitable for double cropping system. ‘Hwangkeumol’ was resistant to bacterial pustule and resistant to soybean mosaic virus, the major soybean diseases in Korea and tolerant to lodging in fields. The average yield of ‘Hwangkeumol’ was 2.51 ton per hectare in the regional yield trials carried out for three years from 2008 to 2010.

A soybean cultivar for soy-paste, ‘Uram’, was developed from the cross between ‘Suwon190’ and ‘SS99244’ (Shinpaldal-2 X T243) by soybean breeding team at the National Institute of Crop Science (NICS) in 2010. A promising line, SS00232-B-B-3SSD-9-4-1-1, was selected and designated as the name of ‘Milyang188’. It was prominent and had good result from regional adaptation yield trials (RYT) in southern area of Korea for three years from 2008 to 2010 and released as the name of ‘Uram’. It has a determinate growth habit, white flower, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape and large seed (25.8 grams per 100 seeds). ‘Uram’ was found to be resistant to bacterial pustule and soybean mosaic virus, the major soybean diseases in Korea. The lowest pod height of ‘Uram’ was 19cm and it will be able to reduce seed loss during mechanical harvesting. The average yield of ‘Uram’ is 3.27 ton per hectare in southern double cropping area. Through these results, ‘Uram’ is soybean cultivar that is favorable for mechanization harvesting, resistant to diseases and highly yield.
