A new sprout-soybean cultivar, "Pungwon" was developed at the Honam Agricultural Research Institute (HARI), and National Institute of Crop Science (NICS) in 2006. "Pungwon" was selected from a cross between S193001 and Suwon 164. The preliminary, advanced, and regional yield trials for evaluation and selection of this line (Iksan 52) were carried out from 2002 to 2006. This cultivar has a determinate growth habit, white flower, grayish brown pubescence, yellow seed coat, yellow hilum, lanceolate leaflet shape and small seed size (10.9 grams per 100 seeds). The maturity date of "Pungwon" is seven days earlier than that of the check variety, "Pungsan". It has a good seed quality for soybean-sprout. The soybean-sprouts grown from "Pungwon" have high isoflavone (5,935 μg/g) and amino acid (160 mg/g) contents. This cultivar has resistance to soybean mosaic virus (SMV), necrotic symptom (SMV-N), and other most troublesome soybean diseases which are bacterial pustule and black root rot. Especially, "Pungwon" has useful characteristics, such as lodging and shattering resistance. The average yield of "Pungwon" was 3.04 ton per hectare, about 7 % higher than the check variety, "Pungsan" at the regional yield trials (RYT) for double cropping.

A new soybean cultivar for soy-paste, “Mansu”, was developed from the cross between ‘Suwon 192’, which was tolerant to disease, late maturing and high yielding, and ‘Suwon 196’ which was early maturing and large seed by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) to make new variety having large seed and high yielding. A promising line, SS97213-2B-3SSD-39-1-1, was selected and designated as the name of ‘Suwon 236’. It was characterized by regional yield trials (RYT) for three years from 2004 to 2006 and released as the name of “Mansu”. It has a determinate growth habit, purple flower, grey pubescence, pale green seed coat, yellow cotyledon, large spherical seed (26.5 grams per 100 seeds). Maturity date is 4 days later than the check cultivar, Taekwang. The average yield of Mansu was 2.93 ton per hectare in the regional yield trials (RYT) carried out for three years from 2004 to 2006 which was 7 percent higher than that of the check cultivar, Taekwang.

A new sprout-soybean cultivar, “Jangki” was developed at the Honam Agricultural Research Institute (HARI) and National Institute of Crop Science (NICS) in 2005. Jangki was selected from a cross between Eunhakong and MS91088. The preliminary, advanced, and
