A New Tofu and Soy-paste Soybean Cultivar, “Daemang 2” with Lodging Tolerance and High Yield

A new soybean cultivar for tofu and soy-paste, “Daemang 2”, was developed from the cross between ‘Shinpaldal 2’ and ‘Seokryang’ by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) in 2005. A promising line, SS93205-2B-8-3-2-1-1-1-1, was selected and designated as the name of ‘Suwon 230’ It was prominent and had good result from regional yield trials (RYT) for three years from 2003 to 2005 and released as the name of “Daemang 2”. It has a determinate growth habit, white flower, grey pubescence, pale green seed coat, yellow cotyledon, flattened spherical seed shape and large seed size (25.3 grams per 100 seeds). It has late maturity date and its ripening period is 12 days longer than the check cultivar, Taekwang. Daemang 2 is tolerant to lodging and resistant to bacterial pustule, and the time of severe leaf disease infection was delayed eleven days than that of Taekwang. The average yield of Daemang 2 was 3.14 ton per hectare in the RYT which was 23 percent higher than that of the check cultivar, Taekwang.
