Abstract
"Wonkwang" is a new sprout-soybean cultivar developed from the cross between Danyeobkong and MS91001 at the Honam Agricultural Research Institute (HARI) and National Institute of Crop Science (NICS), RDA, in 2007. The preliminary, advanced and regional yield trials to evaluate the performance of Iksan 56 were carried out from 2003 to 2007. This cultivar has a determinate growth habit, purple flower, grayish brown pubescence, yellow seed coat, Grayish brown hilum, lanceolate leaflet shape and small seed size (10.9 g/100 seeds). The maturity date of "Wonkwang" is three days later than the check variety, "Pungsan". It has a good seed quality for soybean-sprout and resistance to lodging. The soybean-sprouts grown from "Wonkwang" have high isoflavone ($3,481{\mu}g/g$)contents. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N) and other most troublesome soybean diseases which are bacterial pustule and black root rot. The grain yield of "Wonkwang"in the regional yield trials (RYT) for 3 consecutive years was averaged 3.05 ton per hectare, which was 8% higher than that of the check cultivar "Pungsan".
