‘Sinbaram’ is a new cultivar developed for soy sprout production at the National Institute of Crop Science (NICS). It was developed using the line breeding method in 2010 by artificially crossing ‘Pungsannamulkong’(IT263156) with the ‘HS1371-49-2-2’ line in 2010. F1 plants and the F2 population were developed in 2011 and 2012, respectively, and a promising line was selected using F3 to F5 in the pedigree method. It was evaluated for agronomic traits, yield, and soy sprout characteristics in a preliminary (PYT) and an advanced (AYT) yield trial in 2016 and 2017, respectively. ‘Sinbaram’ has purple flowers, a lanceolate leaflet shape, grey pubescence, and small yellow seeds (10.2 g/100 seeds). The flowering and maturing dates were August 4 and October 9, which were 2 and 5 days earlier than ‘Pungsannamulkong.’ Plant height, first pod height, number of nods, number of branches, and number of pods were 46 cm, 10 cm, 14, 3.5, and 82, respectively. The germination rate and sprout characteristics were similar to those of ‘Pungsannamulkong’, and the yield was 83% higher in the sprout test. In the yield test, the yield was 3.58 tons/ha in the 2-year yield trial, which was 1% higher than that of ‘Pungsangnamulkong,’ and 2.71 tons/ha in the 3-year regional yield trial, 8% lower than that of ‘Pungsannamulkong’, with an average of 2.71 tons/ha in the four regions. In addition, the overall score of 6.7 in the processor survey was higher than 6.0 for ‘Pungsannamulkong.’ Therefore, the ‘Sinbaram’ cultivar is expected to be preferred because it has good sprout characteristics.

‘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.

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 15 cm, 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.

A soybean cultivar for sprout, ‘Joyang 1’ was developed at the National Institute of Crop Science (NICS) in 2010. ‘Joyang 1’ (Iksan67) was released by pedigree selection from the cross between high yielding ‘Pungsannamulkong’ and ‘Suwon187’ tolerant to lodging and disease. It has purple flower, lanceolate leaf, grey pubescence and small yellow seed. Weight of hundred seed is 11.6gram. Maturing date of ‘Joyang 1’ is ten days earlier than check cultivar, ‘Pungsannamulkong’. ‘Joyang 1’ is resistant to bacterial pustule and shattering. It have similar tolerance to root rot and seed spot to check cultivar. It shows high germination ratio, less abnormal germination and hard seed. Sprout yield also 11 percent higher than check cultivar. The average seed yield of ‘Joyang 1’ was 3.03 ton per hectare in the regional yield trials (RYT) carried out for three years from 2008 to 2010 which was 3 percent higher than the check cultivar. The number of breeder’s right is ‘4900’.
