‘Cheongja5’ is a black seed coat soybean cultivar developed from crossing ‘Milyang181’ and ‘YS1886 (Cheongdu1/Tanbaguro)’in 2007. Promising lines were selected using the pedigree method from F3 to F5. The preliminary and advanced yield trials were conductedin 2013 and 2014, respectively. Regional yield trials (RYT) were conducted in seven regions from 2015 to 2017. ‘Cheongja5’ has a determinategrowth habit, oval leaflet shape, brown pubescence, and white flowers. The seed of ‘Cheongja5’ has a black seed coat color with green cotyledon. Flowering and maturing dates were Aug. 3 and Oct. 24, respectively. Regarding the quantitative characteristics, ‘Cheongja5’ has large seedsize (37.0 g/100-seed weight) and more pods than ‘Cheongja3’. ‘Cheongja5’ was tolerant to pod shattering in field and indoor RYT tests. ‘Cheongja5’ was resistant to bacterial pustule in the field and soybean mosaic virus (strains G6H and G7H) in the inoculation test. Althoughits seed quality-related characteristics were almost similar to those of ‘Cheongja3’, it contained more anthocyanin which is a main functionalcomponent of black soybean. The mean yield of ‘Cheongja5’ in the RYTs was 343 kg/10 a which was 30% higher than that of ‘Cheongja3’. ‘Cheongja5’ is expected to be widely cultivated as a material for making soy-food that uses black soybean because of its large seed sizeand high yield potential (Registration No. 7687).
