‘Haewon’ is a soybean cultivar for soy-sprouts. ‘Bosug’ and ‘Somyeong’ were crossed in 2003, and promising lines were selected from F3 to F6 using the pedigree method (Pedigree: HS1450-2B-3-1-1-2-2-1). Preliminary yield (PYT) and advanced yield trials (AYT) were conducted from 2010 to 2011, and regional yield trials (RYT) were conducted in five regions (Suwon, Naju, Miryang, Dalseong, and Jeju) from 2012 to 2014. In the RYTs, ‘Haewon’ had a smaller seed weight and higher yield than the standard cultivar ‘Pungsannamulkong’, which are desirable characteristics for the soy-sprout process. The morphological characteristics of ‘Haewon’ are as follows: determinate plant type, purple flowers, gray pubescence, yellow pods, small, yellow spherical seeds (8.1 g/100-seeds), and light brown hilum. The flowering and maturity dates were July 29th and October 6th, respectively. Plant height and first pod height were 55 cm and 12 cm, respectively. The lodging tolerance was also strong compared to that of ‘Pungsannamulkong’. The germination rate, total length, hypocotyl length, thickness, and sprout yield of soybean sprouts were 97%, 19.1 cm, 8.8 cm, 2.1 mm, and 513%, respectively. The yield in adaptable regions was 337 kg/10 a, 16% higher than that of ‘Pungsannamulkong’. ‘Haewon’ can be used for soy-sprout with favorable seed size and soy-sprout characteristics, such as germination and sprout-yield.
