Abstract

A new black seed coat soybean cultivar, 'Heugseong' was developed at the National Institute of Crop Science (NICS) in 2008. The goal to breed the black seed coat soybean is to develop the cultivar with large seed size, high yield, lodging tolerance, and resistance to disease such as soybean mosaic virus (SMV), and bacterial pustule. 'Heugseong' was selected from the cross between 'Gnome85', showing yellow seed coat, lodging tolerance, and high yield, and 'Cheongja', showing green cotyledon, and black seed coat. The preliminary, advanced and regional yield trials for this cultivar were carried out from 2004 to 2008. It has determinate growth habit, purple flower, brown pubescence, brown pod color, black seed coat, yellow cotyledon, elongated seed shape, oval leaf shape and large seed size (29.2 grams per 100 seeds). It was 4 days later in maturity than the check cultivar 'Ilpumgeomjeongkong'. 'Heugseong' was better than the check cultivar in the seed quality of isoflavone contents(1,913 ${\mu}g/g$). It has good adaptability for cooking with rice in ratio of water absorption and seed hardness, for physics of black tofu, and for fermented black soybean paste. The average yield of 'Heugseong' was 2.37 ton per hectare in the regional yield trials carried out in six locations of Korea from 2006 to 2008.
