A new colored soybean variety ‘Jungmo3005’ was developed as a breeding parent. ‘Cheongjakong’ and ‘Geomjeongkong3’ were crossed in 2000. F1 and F2 populations were grown for 2 years and selected by pedigree method from F3 to F5. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2006 to 2007, and regional yield trial (RYT) in 9 regions was conducted from 2008 to 2010. ‘Jungmo3005’ is determinate, white flower, green cotyledon, green spherical seed and yellow hilum. Flowering date and maturing date were July 30 and Oct. 7, respectively. Other quantitative characteristics of ‘Jungmo3005’ were similar to ‘Cheongdu1’, but it was more tolerant to lodging and shattering than ‘Cheongdu1’ at RYT field and indoor test. Although ‘Jungmo3005’ showed symptom of mosaic disease in inoculation test at greenhouse, it had high level of resistance to soybean mosaic virus and bacterial pustule diseases at field. The yield of tofu of ‘Jungmo3005’ was more than that of ‘Cheongdu1’. The mean yield of ‘Jungmo3005’ in RYT was 256kg/10a which was 97% of the yield of ‘Cheongdu1’. ‘Jungmo3005’ is expected to be widely used as a breeding parent to cross with other varieties and lines for creating colored soybean cultivars with tolerance to lodging, shattering and bacterial pustule.

Soybean cultivar ‘Seonpung’ was developed for soy-paste and tofu. Suwon 224 and YS1325-3S-2 were crossed in 2003 and selected from F3 to F5 by pedigree method. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2009 to 2010, and regional yield trial (RYT) in twelve regions was conducted from 2011 to 2013. In RYT, ‘Seonpung’ was stable in variable environments and a high yield cultivar. ‘Seonpung’ is determinate, white flower, yellow spherical seed and yellow hilum. Flowering date and maturity date were Aug. 5 and Oct. 19, respectively. Plant height was similar to ‘Daewonkong (standard cultivar)’. However ‘Seonpung’ has higher node number (16) and seed weight (25.9g/100-seed weight) than ‘Daewonkong’ (14 and 24.2g/100-seed weight). ‘Seonpung’ is resistant to root rot, and it also has high level of resistance to bacterial pustule and soybean mosaic virus. The yield of tofu of ‘Seonpung’ was 241%, and noticeably lighter, and solidity was higher than ‘Daewonkong’. Soybean malt scent, fermented soybean yield and γ-polyglutamic acid (γ-PGA) of ‘Seonpung’ were 4, 181% and 31.7㎎/g. The yield in adaptable regions was 340kg/10a (21% increase compared to ‘Daewonkong’). ‘Seonpung’ is expected to be cultivated and used widely for soy-paste and tofu. (Registration number: 5931)

Early maturity of soybean (Glycine max (L.) Merr.) is an important character for double cultivating system with winter crops such as onion or garlic in southern area of Korea. Soybean cultivars released in the past, especially ‘Keunolkong’ was widely cultivated but it was weak at abiotic stress and low yield potential because of too short growing period and short stem height. ‘Hanol’, a new early maturing cultivar showing better abiotic stress tolerant and higher yield potential, was developed from the cross between SS91408 and ‘Hwaeomputkong’, and released in 2009. ‘Hanol’ is, compared to ‘Keunolkong’, Hanol’s growing period is five days longer and its height is 5cm higher. In addition, it showed better excess-water tolerant and 26.5g 100-seed weight. At regional adaptation yield trials (RYT) in six regions from 2007 to 2009, ‘Hanol’ showed 2.04 tons of seed per hectare, 14% higher than ‘Keunolkong’ (1.80ton/ha). ‘Hanol’ is promising for double cropping system with higher yield.

Doenjang is one of the most favorite traditional food which was produced by the fermentation process of soybean with various microbes such as Aspergillus oryzae, Bacillus subtilis and so on. The aim of this research is to analyse the antioxidant and anti-α-glucosidase inhibitory activities of doenjang made by 9 different cultivar (Daewonkong, Taekwangkong, Daepungkong, Hwangkeumkong, Saedanbaek, Hanolkong, Pungsannamulkong, Cheongja-3 and Cheongdu-1). Doenjang samples were made by traditional manner using rice straw. Each samples were extracted with 40% methanol and extract were used Among them, cheongja-3‘s doenjang showed a significant highest antioxidant and anti-α-glucosidase inhibitory activities because of its anthocyanin. Except for cheongja-3's Doenjang, antioxidant activity had positive correlation with isoflavone content. But no relationship observed between isoflavone content and anti-α-glucosidase activity. The highest anti-α-glucosidase activity was observed in Saedanbaek's Doenjang with highest protein content.

Soybean isoflavones include daidzein, genistein and glycitein with their glycosides, and their malonated derivatives are the main polyphenolic compounds that are helpful for human health. Our research objective was to investigate the differentitation of soybean isoflavones contents of breeding populations between yellow and black soybean. Isoflavones contents in soybean are a wide range from 500 to 7000 ㎍/g. In this study, we used Ilmi (Isoflavones content, 3.612 ㎍/g) as male parent and 04GAYT-4 (Isoflavones content, 1,648 ㎍/g) as female parent. From these varieties, we obtained 94 breeding lines (yellow, 48 lines; black, 25 lines; brown, 21 lines) which have isoflavones content range from 1000 to 6000 ㎍/g. Highest isflavone contents of three different breeding lines was yellow seed coated lines (average isoflavone content, yellow 3,046 ㎍/g, brown 2,935 ㎍/g, black 2,813 ㎍/g).

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 cultivar, “Heugmi” 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. Heugmi 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 Milyang 68, which was middle maturing, resistant to lodging and SMV and with middle seed size and yellow cotyledon. The preliminary, advanced and regional yield trials for evaluation and selection of this cultivar were carried out from 2001 to 2006. It has determinate growth habit, purple flower, brown pubescence, black pod color, black seed coat, green cotyledon, spherical seed shape, oval leaf shape and middle seed size (24.8 grams per 100 seeds), and it was 2 days earlier in maturity than the check cultivar Cheongjakong. Heugmi was better in the seed quality of crude protein contents, sucrose and total sugar contents than the check cultivar. It also has been identified to have resistance to SMV which was the troublesome soybean diseases. The average yield of Heugmi was 2.53 ton per hectare in the regional yield trials carried out in seven locations of Korea from 2004 to 2006, which was 8 percent higher than the check cultivar Cheongjakong.
