A new sprout-soybean cultivar, “oseo”was developed at the Honam Agricultural Research Institute (HARI) in 2007. Hoseo was selected from a cross between Camp and Nattosan. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 57 were carried out from 2003 to 2007. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, yellow seed coat, grayish brown hilum, rhomboid leaflet shape and small seed size (7.4 g/100 seeds). The maturity date of “oseo”is 12 days earlier than the check variety, “ungsan” It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N). The average yield of “oseo”was 2.51 ton per hectare in the regional yield trials (RYT) for double cropping carried out for three years from 2005 to 2007.
