A new soybean cultivar ‘Cheonga’ was released by Gangwondo Agricultural Research & Extension Services, Republic of Korea in 2009. The Goal of breeding was for high yield, lodging tolerance, and resistance to diseases such as Soybean mosaic virus and bacterial pustule. The ‘Cheonga’ was selected from progenies obtained from a cross between ‘Shinpaldal 2’, showing yellow seed coat, lodging tolerance and high yield, and ‘SS91809’, showing yellow seed coat, lodging tolerance and early maturity. It has a determinate growth habit, white flower, yellow seed coat, yellow hilum and large spherical seed (25.2 g per 100 seeds). The ‘Cheonga’ has 11 days early in flowering date and 5 days early in maturity than the check cultivar ‘Taekwang’. The ‘Cheonga’ has 6days longer in maturity period than the check cultivar. The ‘Cheonga’ is partial tolerant to soybean mosaic virus and bacterial pustule, the major soybean disease in Korea. Especially, ‘Cheonga’ shows lodging tolerance. The average yield of ‘Cheonga’ was 2.72 ton per hectare in the regional yield trials carried out in two years from 2006 to 2007, which was 14percent higher than that of check cultivar, ‘Taekwang’.
