A new soybean cultivar for soybean sprout, ‘Wonheug’ was developed at the National Institute of Crop Science (NICS)in 2009. ‘Wonheug (Iksan63)’ was released from the cross between F1 of YS1286 (Tawonkong/Jinju#1) and Jinju#1. It has purpleflower, oval shaped leaf, tawny pubescence and small black seed (8.8 g/100 seed). Maturing date of ‘Wonheug’ is ten days laterthan check cultivar, ‘Tawonkong’. Even though mosaic symptom can be observed by artificial inoculation, ‘Wonheug’ is tolerantto virus and bacterial pustule at field. It has similar tolerance to a check cultivar for excess water and seed spot. ‘Wonheug’produce more soy-sprout than a check cultivar because it shows high in germination ratio, low in rate of abnormal germinationand hard seed. The average yield of ‘Wonheug’ was 2.34 ton per hectare in the regional yield trial (RYT) carried out for threeyears from 2007 to 2009, which was 12 percent higher than check cultivar, ‘Tawonkong’.
