영문 초록

‘Taecheong’ is a black soybean cultivar developed from crossing ‘YS1593(Milyang136 × Tanbaguro)’ and ‘Cheongja2’ in 2005. F1 and F2 populations were grown for 2 years and promising lines were selected by pedigree method from F3 to F5. The preliminary yieldtrial (PYT) and advanced yield trial (AYT) were conducted from 2012 to 2013, and a regional yield trial (RYT) in seven regions was conductedfrom 2014 to 2016. ‘Taecheong’ is determinate, with purple flower, green cotyledon, and black spherical seed. Flowering date and maturingdate were August 3 and October 20, respectively. Regarding quantitative characteristics, ‘Taecheong’ has a larger seed size (44.5 g/100-seedweight) than that of ‘Cheongja3’ (35.8 g/100-seed weight). ‘Taecheong’ was tolerant to pod shattering and lodging at the RYT field andindoor test. In addition, ‘Taecheong’ was resistant to bacterial pustule during the field test, and to soybean mosaic virus (G6H strain) duringthe inoculation test. Although its seed quality-related characteristics were similar to those of ‘Cheongja3’, it contained more anthocyanin inits seed-coat, which is a primary functional component of black soybean. The mean yield of ‘Taecheong’ in RYT was 240 kg/10a, whichwas 94% of the yield of ‘Cheongja3’. ‘Taecheong’ is expected to be used as raw material for soy products, such as for preparing soybeanchocolates, because of its large seed size (Registration number: 7104).
