A new mung bean cultivar, Vigna radiata (L.) R. Wilczek ‘Samhwang’, was derived from a cross between ‘Samgang’ and ‘KM9901-3B-15-2-4’ obtained in 2006 and developed at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2014. ‘Samhwang’ has an erect growth habit, lobed leaflets, green hypocotyls, light yellow corolla, and a dull yellow seed surface. Its stem length was 64 cm, 5 cm shorter than that of the control cultivar ‘Owool’. The 1000-seed weight was 53 g, i.e., 4 g heavier than that of ‘Owool’. ‘Samhwang’ exhibited similar field resistance to mung bean mottle virus, cercospora leaf spot, powdery mildew, and lodging when compared with that of the control cultivar. The sprout yield ratio and hard seed rate were the same as those of ‘Owool’. The average seed yield of ‘Samhwang’ was 1.76 ton/ha, which was 14% greater than that of ‘Owool’ (Registration No. 5877).

A mungbean (Vigna radiata (L.) Wilczek) cultivar Jinhwang was derived from a cross between Samgang and KM9901-3B-15-2-4 and developed at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2013. Jinhwang has an erect growth habit, heart leaflets, green hypocotyls, light yellow corolla, and a dull yellow seed surface. The stem length of Jinhwang was 61 cm, which was 5 cm shorter than that of the control cultivar Owool. The 1000-seed weight was 52 g, which was 3 g heavier than that of Owool. Jinhwang has similar field resistance to mungbean mottle virus, cercospora leaf spot, powdery mildew, and lodging to the control cultivar. The hard seed rate of Jinhwang was 6.2%, which was 1.8%p higher than that of Owool. The sprout yield ratio was the same as that of the control cultivar. The average seed yield of Jinhwang was 1.68 ton/ha, which was 5% greater than that of Owool. (Registration No. 5873)

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.

Soybean is the main source of protein and oil for human and animal nutrition. However, antinutritional factors in the raw mature soybean are exist. Lipoxygenase protein is the main antinutritional factor in mature soybean seed. A new soybean cultivar, ‘Jinyang’ with yellow seed coat and free of lipoxygenase 1,2,3 protein was developed. It was selected from the population derived from the cross between ‘Jinpumkong2ho’ and GS301. ‘Jinyang’ has purple flowers, tawny pubescence, a determinate growth habit, oval leaflet shape, and light brown pods at maturity. The seed has yellow hilum and yellow seed coat color. Seed protein and oil content on a dry weight basis were 33.5% and 16.6%, respectively. It has shown a resistant reaction to soybean necrosis, soybean mosaic virus, cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. ‘Jinyang’ matured in 1 October with plant height of 65cm and a 100-seed weight of 21 g. Average yield of ‘Jinyang’ was 300 - 330 kg/10a in 2010 - 2012. ‘Jinyang’ has been registered as a new soybean cultivar (registration number: 4279, registration date: Dec. 28, 2012) by Korea Seed & Variety Service, Republic of Korea.
