A soybean cultivar “Chamol” for double cropping for use as soy-paste and tofu was developed using a pedigree method in 2011 as a cross between “Shinpaldal2” and “Keunol.” A promising line, SS99502-2B-89-1-3-4-1-1, was selected and designated as “Milyang210”. It was promising and showed good results from regional yield trials (RYTs) for 3 years from 2009 to 2011 and released with the name “Chamol.” It has a determinate growth habit, white flowers, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape, and large seeds (27.7 g per 100 seeds). The maturity date of “Chamol” was September 18 (100 day growing period) in RYT and it is suitable for double cropping with winter crops such as onion. “Chamol” was resistant to bacterial pustule and soybean mosaic virus and tolerant to lodging in fields. Furthermore, the average yield of “Chamol” was 2.51 ton/ha in the regional yield trials conducted for 3 years from 2009 to 2011.
