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

초록

“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 “Danmi2”, designated as Milyang 145 in 2002, was YS1307-2B-1-G-1. Vegetable soybean “Danmi 2” was characterized as lipoxygenase1- and 2-free, large seed, very short plant height, and lodging resistance. “Danmi 2” has determinate growth habit, white flower,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 “Hwae-omput”. Harvesting date of green pod in “Danmi 2” was Aug. 8 which was 4 days later than Hwaeomput and its stem height was9 cm shorter than Hwaeomput. In the same trials, fresh pod of “Danmi 2” (11.61 ton ha1) yielded 9% higher than Hwaeomput(10.68 ton ha1). “Danmi 2” had 6.7 cm fresh pod length, 12.7 m fresh pod width, 79.3 g 100-green seed weight, 41.1% greenseed protein content, and 20.0% green sed oil content. SDS-PAGE on grain storage protein shows that “Danmi 2” was deficient inlipoxygenase 1 and 2.
