A New Vegetable Soybean Cultivar, “Danmi 2” with free of Lipoxygenase 1 and 2

“Danmi 2”, a new cultivar for vegetable soybean, was developed from the cross between “Seokryangput” and “YS1307” (Seokryangput/Milyang77) at Yeongnam Agricultural Research Institute and released in 2005. The pedigree of “Danmi 2”, designated as Milyang 145 in 2002, was YS1307-2B-1-G-1. Vegetable soybean “Danmi 2” was characterized as lipoxygenase 1- and 2-free, large seed, very short plant height, and lodging resistance. “Danmi 2” has determinate growth habit, white flower, gray pubescence, very short stem height, oval leaf shape, and brown pods at maturity. The mature seeds have a green yellow seed coat with brown hilum and yellow cotyledon. Over 3 years of Korea regional adaptation tests (2003-2005) for vegetable soybean, “Danmi 2” showed moderate resistance to soybean mosaic virus and lodging, and higher resistance than the check cultivar “Hwaeomput”. Harvesting date of green pod in “Danmi 2” was Aug. 8 which was 4 days later than Hwaeomput and its stem height was 9 cm shorter than Hwaeomput. In the same trials, fresh pod of “Danmi 2” (11.61 ton ha⁻¹) yielded 9% higher than Hwaeomput (10.68 ton ha⁻¹). “Danmi 2” had 6.7 cm fresh pod length, 12.7 mm fresh pod width, 79.3 g 100-green seed weight, 41.1% green seed protein content, and 20.0% green seed oil content. SDS-PAGE on grain storage protein shows that “Danmi 2” was deficient in lipoxygenase 1 and 2.
