Soybean Cultivar, “Choseon” : Cultivar with Yellow Medium Seed Size and Lipoxygenase 2,3 Protein-free

초록

Soybean [Glycine max (L.) Merr.] is an important source for protein, oil, carbohydrates, isoflavones, and many other nutrients to humans and animals. Lipoxygenase protein is the main antinutritional factor in mature soybean seed. Soybean cultivar, "Choseon" with yellow medium seed size and free of lipoxygenase 2,3 protein was developed. "Choseon" was selected from the population derived from the cross between cultivar, "Jinpum 2" and germplasm, PI408155. "Choseon" has purple flowers, tawny pubescence, a determinate growth habit, and light yellow pods at maturity. The seed of "Choseon" has yellow hilum and yellow seed coat color. Seed protein and oil content on a dry weight basis were 34.2 and 16.9%, respectively. "Choseon" has shown a resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and bacterial pustule. "Choseon" matured in 5 October with plant height of 51 cm and a 100-seed weight of 15.1 g. Average yield of "Choseon" was 2.66 (Ton/ha) on the regional yield trials of 2013 at 4 locations. "Choseon" has been registered as a soybean cultivar (registration number: 5985, registration date: April 11, 2016) by Korea Seed & Variety Service, Republic of Korea.
