Abstract
‘Haepum’ is a soybean cultivar for soy sprouts. ‘Bosug’ and ‘Suwon 214’ were crossed in 2001, and promised lines were selected from F3 to F5 using the pedigree method (Pedigree: HS1273-2B-4-1-2-3-3). Preliminary yield (PYT) and advanced yield (AYT) trials were conducted from 2008 to 2009, and regional yield trials (RYT) in four regions (Suwon, Naju, Miryang, Jeju) were conducted from 2010 to 2012. In RYT, ‘Haepum’ had higher plant height and first pod height than other cultivars, which are desirable characteristics for mechanized harvest. Morphological characteristics of ‘Haepum’ are as follows: determinate, white flowers, grey pubescence, yellow pods, yellow spherical small seeds (10.4 g/100 seeds), and light brown hilum. The flowering and maturity dates were July 29 and October 6, respectively. Plant height was 61 cm, 6 cm longer than that of ‘Pungsannamulkong’ (standard cultivar). Moreover, the first pod height of ‘Haepum’ was 15cm, 6 cm longer than that of ‘Pungsannamulkong’. The lodging tolerance was also stronger (1) than that of ‘Pungsannamulkong’ (6). The germination rate, total length, hypocotyl length, thickness, and sprout yield of ‘Haepum’ soybean sprouts were 99%, 20.6 cm, 9.7 cm, 2.1 mm, and 453%, respectively. The yield in adaptable regions was 301 kg/10 a, which was 10% higher than that of ‘Pungsannamulkong’. ‘Haepum’ could be broadly used for soybean sprout culture and an adequate cultivar for conversion to jeju and mechanized harvesting.
