AbstractIn 2014, a mung bean cultivar, Vigna radiata (L.) R. Wilczek ‘Dado’, was derived from a hybrid between ‘Jeonnam14’ and ‘IT208777’ developed in 2001 at the Jeollanamdo Agricultural Research and Extension Services, South Korea. ‘Dado’ has an erect growth habit, lobed leaflets, green hypocotyls, light yellow corolla, and dull green seed surface. The number of pods per plant was 23.3, 1.5 more than that of the control cultivar ‘Owool’, and the 1000-seed weight was 43 g, 6 g lighter than that of the control. ‘Dado’ and ‘Owool’ exhibited similar field resistance to mung bean mottle virus, cercospora leaf spot, powdery mildew, and lodging. ‘Dado’ had a sprout yield ratio of 824%, 132% higher than that of ‘Owool’, and its hard seed rate was 1.2%, 3.1% lower than that of the control. The average seed yield of ‘Dado’ was 1.9 ton/ha, which was 23% greater than that of ‘Owool’ (Registration No. 5874).

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 cultivar ‘Areum’ (Vigna radiata (L.) Wilczek) was derived from a cross between ‘Samgang’ and ‘KM9901-3B-15-2-4’ at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2013. ‘Areum’ has an erect growth habit, lobed leaflet, green hypocotyls, light yellow corolla, and a dull green seed surface. Its stem length is 61 cm, which is 5 cm shorter than that of the control cultivar ‘Owool’. The 1000-seed weight is 51 g, which is 2 g heavier than that of ‘Owool’. Its field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew is similar to that of the control cultivar, whereas its field resistance to lodging is marginally weaker. The hard seed rate of ‘Areum’ is 6.81%, which is 2.49% higher than that of ‘Owool’. The sprout yield ratio is 7.09, which is similar to that of the control cultivar. The average yield of ‘Areum’ is 1.79 ton/ha, which is 12% more than that of ‘Owool’. (Cultivar registration number: 5876).
