A soybean cultivar ‘Yonpoong' which has safety high yield for double cropping system introduced winter forage crop was released by agricultural resource research institute of ARES, Gyeunggi Province in 2010. The goals of breeding were for large seed size, high yield, and resistance to disease such as spotting disease. ‘Yonpoong' was derived from the cross of ‘Suwon 191', which large seed size and high yield, and ‘Suwon 126', which early maturity cultivar, and short stem. The preliminary, advanced and regional yield trials for evaluation and selection were carried out from 2005 to 2010. ‘Yonpoong' has a determinate growth habit with purple flower, grey pubescence, brown pod color, yellow seed coat, yellow cotyledon, elongated seed shape, large seed size(28.7 g per 100 seeds). The maturing date was sept. 22. Tofu yield was similar to that of check cultivar ‘Daewonkong'. The average yield of ‘Yonpoong' was 3.34 MT/ha in the regional yield trials(RTY) carried out in Korea from 2008 to 2010 which 38 percent higher than the check cultivar ‘Daewonkong'.

A new soybean cultivar ‘Manpoong' for tofu soybean was released by ARES, Gyeunggi Province in 2009. The goals of breeding were for large seed size, high yield, and resistance to disease such as bacterial pustule. ‘Manpoong' was derived from the cross between ‘Dongsan 121', which has large seed size, yellow seed coat, and characteristics of superior tofu, and ‘Sprite 87', which has early maturity. The preliminary, advanced and regional yield trials for evaluation and selection were carried out in 2003 and from 2005 to 2009, respectively. ‘Manpoong' has a determinate growth habit with white flower, grey pubescence, dark brown pod color, yellow seed coat, yellow cotyledon, elongated seed shape, and large seed size(29.5 g per 100 seeds). The maturing date was Sept. 29. The content of crude protein, crude oil, unsat. fatty acids, isoflavone, total amino acid which affected the production rate of tofu was higher than those of the check cultivar ‘Taekwangkong'. The production rate of tofu was 15 percent higher than the check cultivar ‘Taekwangkong'. The average yield of ‘Manpoong' was 2.87 MT/ha in the regional yield trials(RYT) carried out in two location at double cropping system in Korea from 2007 to 2009, which was 12 percent higher than the check cultivar ‘Taekwangkong'.

The soybean cultivar ‘Gangpoong’ was developed for soy-paste and tofu. Suwon 223 and SS 00419 were crossed in 1999 and their progenies were selected from F3 to F5 using the pedigree method. Preliminary yield (PYT) and advanced yield (AYT) trials were conducted from 2008 to 2010, and regional yield trials (RYT) were conducted at three locations from 2011 to 2013. In RYT, ‘Gangpoong’ was stable in variable environments. ‘Gangpoong’ was determinate, with white flowers, yellow elongated spherical seeds, and a light brown hilum. The flowering and maturity dates were July 27 and October 8, respectively. The plant height was 67 cm shorter than that of ‘Daewonkong’ (81 cm, standard cultivar). ‘Gangpoong’ had fewer node numbers (16) than that of ‘Daewonkong (18) and had a heaver seed weight (30.1 g/100-seed weight) than that of ‘Daewonkong (26.0 g/100-seed weight)’. ‘Gangpoong’ showed lodging tolerance. The tofu yield of ‘Gangpoong’ was 213%, and the physical characteristics of tofu were similar to those of ‘Daewonkong (208%, standard cultivar)’. The soybean malt scent and fermented soybean yield of ‘Gangpoong’ were 2 and 105%, respectively. The yield in adaptable regions was 3.4 MT/ha, which was 14% higher than that of ‘Daewonkong’. Therefore, ‘Gangpoong’ could be cultivated and used widely for soy-paste and tofu in the near future (Registration number: 5932). [ABSTRACT FROM AUTHOR]

A new soybean variety, ‘Joongmo 3009' (Milyang 222) was developed at the National Institute of Crop Science (NICS) in 2012. ‘Joongmo 3009' was released by pedigree selection from the cross between ‘Cheongja 2(Milyang 121)' and ‘Daemangkong'. It has determinate growth habit, white flower, brown pubescence, brown pod color, green seed coat, green cotyledon, spherical seed shape, oval leaf shape and large seed size (29.3 grams per 100 seeds). It was late 16 days in maturing date than the check cultivar ‘Cheongjakong'. The average yield of ‘Joongmo 3009' was 2.91 ton per hectare, which was higher 36 percentage than the check variety, in the regional yield trials carried out in three adaptable locations of Korea from 2010 to 2012. The number of breeder's right is ‘5474' [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
