‘Cheongmiin’ is a green seed-coated soybean cultivar developed from a cross between ‘Cheongjakong’ and ‘Daemang’ in 2002. The F₁ and F₂ populations were grown for 2 years, and promising lines were selected based on the pedigree method from generations F₃ to F₅. Preliminary and advanced yield trials were conducted from 2009 to 2010, and regional yield trials (RYTs) were conducted in eightregions from 2011 to 2013. ‘Cheongmiin’ is a determinate soybean with white flowers, green cotyledons, and spherical green seeds. Theaverage flowering and maturing dates of ‘Cheongmiin’ were August 1st and October 22nd, respectively. In terms of quantitative characteristics,‘Cheongmiin’ has a larger seed size (34.3 g/100-seed weight) than that of ‘Cheongdu1ho’ (24.5 g/100-seed weight), and has also been shownto be tolerant to lodging and pod shattering in the field in RYTs and oven drying tests, respectively. Furthermore, ‘Cheongmiin’ has beenfound to be resistant to bacterial pustules in the field and soybean mosaic viruses (G5H and G6H strains) in inoculation tests. The meanyield of ‘Cheongmiin’ in the RYTs was 272 kg/10 a, which was 4% higher than that of ‘Cheongdu1ho’. Given its large seed size and seedcoat color, ‘Cheongmiin’ is expected to be highly useful for cooking with rice and for the preparation of rice cakes (Registration No. 7688).
