　A new sprout-soybean cultivar, “oseo”was developed at the Honam Agricultural Research Institute (HARI) in 2007. Hoseo was selected from a cross between Camp and Nattosan. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 57 were carried out from 2003 to 2007. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, yellow seed coat, grayish brown hilum, rhomboid leaflet shape and small seed size (7.4 g/100 seeds). The maturity date of “oseo”is 12 days earlier than the check variety, “ungsan” It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N). The average yield of “oseo”was 2.51 ton per hectare in the regional yield trials (RYT) for double cropping carried out for three years from 2005 to 2007.

Lipoxygenase is responsible for the beany flavor and soybean kunitz trypsin inhibitor protein is responsible for the inferior nutritional quality of unheated or incompletely heated soybean meal. Anthocyanins from black soybean seed coat are known to have many pharmaceutical effect. The object of this study is to select black soybean genotype with absence of lipoxygenase-2,3 (Lx1Lx1lx2lx2lx3lx3) and small seed size. Two cultivars (“Seomoktae” and "Gaechuck#1") were used. "Seomoktae" cultivar has the traits of small seed size, black seed coat, green cotyledon and lipoxygenase protein. "Gaechuck#1" has the traits of big seed size, black seed coat, green cotyledon and lipoxygenase free protein. In the F2 population, the several plants with small seed size and lipoxygenase free protein were selected. In F3 and F4 generation, seed size and lipoxygenase protein was comfirmed from the bulked seed harvested at field. The F5 seeds with small seed size and Lx1Lx1lx2llx2lx3lx3 genotype were planted in the field. Several agronomic traits were evaluated. The lines with appropriate agronomic traits were selected.

Isoflavone concentration(daidzein, glycitein, and genistein) of soybean(Taekwangkong and Sowonkong) were analyzed for studying the relationship between seed size and isoflavone concentration and seed coat color and isoflavone concentration. The isoflavone concentration was the greatest in daidzein then followed by genistein, however glycitein was the smallist of all. The isoflavone concentration was increased with the increasing of the ripening degree and seed size.

A new sprout-soybean cultivar, "Jonam" was developed at the Honam Agricultural Research Institute (HARI) in 2006. Jonam was selected from a cross between Eunhakong and Jeonju-I1. The preliminary, advanced, and regional yield trials for evaluation and selection of this line (Iksan 48) were carried out from 2002 to 2006. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, grayish brown hilum, lanceolate leaflet shape and small seed size (9.6 grams per 100 seeds). The maturity date of "Jonam" is 18 days earlier than that of the check variety, "Pungsan". It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom(SMV-N). The average yield of "Jonam" was 2.57 ton per hectare in the regional yield trials for double cropping carried out for three years from 2004 to 2006.

A new garden pea cultivar, Daehyup 2, was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. It was selected from the cross between Olwandu and Sachulwandu in 1996. The preliminary, advanced, and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2006. It has white flower, yellow cotyledon, absent or very weakly curved pod shape and yellow seed color. It was resistant to virus and powdery mildew disease. The 100 green seed weight of Daehyup 2 was 65.5 g, which was 8.9 g heavier than check cultivar. The sucrose and total sugar contents of fresh pod of Daehyup 2 were 11.1% and 12.5%, respectively, which were 3.2% and 4.3% higher than those of Sachulwandu. The fresh pod yield of Daehyup 2 was similar to that of Sachulwandu with 12.16 ton per hectare in the regional yield trials carried out in three locations of Korea from 2005 to 2006.

A new black seed coat soybean variety, “Socheong” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Socheong was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Peking which was tolerant to lodging and with small seed size. The preliminary, advanced and regional yield trials for evaluation and selection of this variety were carried out from 2002 to 2006. It has determinate growth habit, white flower, brown pubescence, brown pod color, black seed coat, green cotyledon, elongated flattened seed shape, oval leaf shape and small seed size (15.7 grams per 100 seeds), and it was 3 days later in maturity than the check cultivar Cheongjakong. Socheong was higher, in the seed quality of sucrose and total sugar contents (6.8 and 8.2%) and isoflavone contents (1,754 ㎍/g) than the check cultivar. Futhermore, it has good characteristics for mechanical harvest, such as lodging tolerance, pod shattering and stem diameter. It also has been identified to have resistance to soybean mosaic virus symptom which was the troublesome soybean diseases. The average yield of Socheong was 2.21 ton per hectare in the regional yield trials carried out in four locations of Korea among seven locations from 2004 to 2006, which was 5 percent lower than the check cultivar Cheongjakong.

A new sprout-soybean cultivar, “Wonhwang” was developed at the Honam Agricultural Research Institute (HARI) in 2005. Wonhwang was selected from a cross between Camp and Myeongjunamulkong. The preliminary, advanced, and regional yield trials for evaluation and selection of Iksan45 were carried out from 2001 to 2005. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, grayish brow hilum, lanceolate leaflet shape and small seed size (10.0 grams per 100 seeds). The maturity date of Wonhwang is 7 days earlier than that of the check variety, Pungsan. It has good seed quality for soybean-sprout, and resistance to lodging. It has also been identified to have resistance to soybean mosaic virus (SMV) and necrotic symptom(SMV-N). The average yield of “Wonhwang” was 2.80MT/ha, which was higher by 4% than “Pungsannamulkong” at the regional yield trials.

Soyasaponins A1 , DDMP-conjugated group B soyasaponins αg~;and~;βg , non-DDMP counterpart soyasaponin I, II+III, and DDMP moiety were quantified in the large-, midium-, and small-seed soybean varieties. Protein contents were ranged from 38.1% to 41.8%, and oil contents were ranged from 15.5% to 18.9%, respectively. Oil contents in the large-seed varieties were significantly higher than those of medium- and small-seed varieties. Among detected soyasaponin peaks, βg was a major soyasaponin in DDMP-conjugated group B soyasaponins followed by soyasaponin I, DDMP moiety and A1 . Soyasaponin concentration among different seed size soybean varieties. The soyasaponin concentration of mediumseed (4014.5~mug/g ) was slightly higher than those of largeseed (3755.0~mug/g ) and small-seed varieties (3620.3~mug/g ), however, the differences was statistically not significant. The composition rates of soyasaponins in the large-size seeds were 9.4% of soyasaponin A1 , 26.5% of DDMP-conjugated soyasaponins, 49.9% of non-DDMP counterpart soyasaponins, and 14.2% of DDMP moiety, respectively. Similar results were observed in the composition ratios of middle- and small-size seeds. Oil content and C:N ratio showed the significant positive correlations with total soyasaponin concentration, while the 100-seed weight, fiber, and ash contents showed the negative correlations with total soyasaponin but statistically not significant. It was noted that protein contents didn't have any relationship with group A, group B, DDMP moiety, and total soyasaponin. This fact suggested that protein contents are not affects the variation of soyasaponin concentration.
