A new soybean [Glycine max (L.) Merr.] cultivar, ‘Dadrim,’ was developed by the National Institute of Crop and Food Science (NICS). ‘Dadrim’ is characterized by its superior suitability for tofu processing and high adaptability to mechanized cultivation. This cultivar ‘Milyang374’ was developed using the pedigree method from an artificial cross made in 2012 between ‘Milyang231’ and ‘Chamol.’ Its agronomic characteristics and production stability were verified through regional adaptation trials conducted over three years (2020- 2022). ‘Dadrim’ exhibits a determinate growth habit, white flowers, and spherical seeds with a yellow seed coat and yellow hilum. It is a large-seeded variety with a 100-seed weight of 30.9 g. As a late-maturing variety, it reaches maturity around October 22. Despite a relatively short plant height, it features a high first pod height of 16 cm, making it advantageous for mechanical harvesting. ‘Dadrim’ is resistant to bacterial pustule and soybean mosaic virus and possesses excellent lodging resistance. Notably, ‘Dadrim’ demonstrates a high tofu yield of 283%, which is 67% points higher than ‘Daewonkong’. The resulting tofu has a soft texture, making it suitable for soft and silken tofu. It also received high preference scores for taste and texture in sensory evaluations. ‘Dadrim’ yielded 3.37 tons/ha, an 8% increase compared to ‘Daewonkong.’ This new variety is expected to increase farm income and advance the domestic tofu industry (Registration No. 10461).
