Leaf of a soybean landrace and introduced variety from Japan, ‘Danpaheug’, have been extensively used as a vegetable for wrapping with fish and meat in Jeju province and southern part of the Korea but it had poor leaf quality because of ununiform size of leaves. Therefore, development of soybean cultivars for vegetable leaf is required. A new soybean cultivar for vegetable leaf with black seed coat, ‘Cheongyeob 1’ was developed at the National Institute of Crop Science (NICS), Milyang, in 2009. The ‘Cheongyeob 1’ was selected from the cross between ‘Ilpumgeomjeong’, yellow seed coat, lodging tolerance, and high yield,and ‘Daehwang’, large seed size and leaves. It had white flower, black seed coat, yellow cotyledon, spherical flattened seed shape, oval leaf shape and large seed size (35.8 grams per 100 seeds). It also had the special features for vegetable use of the soybean leaves such as late flowering large and round shape of light green leaf, lodging tolerance, many stem nodes, and thick stem diameter. The soybean leaf yield of the ‘Cheongyeob 1’ cultivated at the green house recorded 18.44 ton per hectare which was 6% higher than that of the control ‘Danpaheug’. The farmer’s leaf income of ‘Cheongyeob 1’ was also high with 81.68million won per hectare which was 93% higher than the control landrace. In addition, the soybean leaf had high isoflavone contents with 809 μg/g which was 63% higher than that of the control ‘Danpaheug’. This result indicates that the new black seed coat soybean cultivar, ‘Cheongyeob 1’ is a suitable for a vegetable use of leaves.
