Abstract
A new sprout-soybean cultivar, "Galchae" was developed at the National Institute of Crop Science (NICS) in 2008. Galchae was selected from a cross between YS1287 and Jinju#1. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 64 were carried out from 2005 to 2008. This cultivar has a determinate growth habit with purple flower, brown pubescence, brown seed coat, brown hilum, rhomboid leaflet shape and small seed size (8.4 grams per 100 seeds). The maturity date of "Galchae" is 6 days later than the check variety, "Dawon". 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 "Galchae" was 2.51 ton per hectare in the regional yield trials (RYT) for double cropping carried out for two years from 2007 to 2008.
