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 (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)

A cowpea cultivar Vigna unguiculata L. Walp ‘Seonhyeon’ is a cross species between V. unguiculata ‘IT145373’ and V. unguiculata ‘IT101362’ developed at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2017. ‘Seonhyeon’ is an erect plant with an intermediate plant habit, green hypocotyls, light purple-colored corolla, heart-shaped leaflets, black seed surface, and straight, brown mature pods. The anthocyanin content of ‘Seonhyeon’ was 1,632 µg/g, and it contained seven anthocyanins, including cyanidin-3-glucoside and delphinidin-3-glucoside. The stem length of ‘Seonhyeon’ was 54 cm, which was 13 cm longer than that of the control cultivar ‘Okdang’. Its 100-seed weight was 11.8 g, which was 3.6 g lighter than that of the control cultivar. Field resistance of ‘Seonhyeon’ to leaf and systemic diseases was similar to that of the control cultivar, whereas its field resistance to lodging was slightly lower compared to that of the control cultivar. The average yield of ‘Seonhyeon’ was 2.26 ton/ha, which was 15% higher compared to that of control cultivar. Black seed coat of the ‘Seonhyeon’ cultivar is expected to contribute to species specialization as well as to development of various processed products. (Registration number: 7499)

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).

A mungbean cultivar “Munpyeong” (Vigna radiata (L.) Wilczek) was derived as a cross between “Keumseong” and “IT163157” at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2013. “Munpyeong” has an erect growth habit, heart leaflet, green hypocotyls, black and straight pods when matured, and a dull green seed surface. The stem length of “Munpyeong” was 60 cm, which was 6 cm shorter than that of the control cultivar “Owool.” The pod number per plant was 25, which was 3 more than that of the control cultivar. The 1000 seed weight of “Munpyeong” was 45 g, which was 4 g lighter than that of the control cultivar “Owool.” Its field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew are similar to the control cultivar, whereas its field resistance to lodging was slightly stronger. The hard seed rate of “Munpyeong” was 3.2%, which was similar to that of the control cultivar. The sprout yield ratio was 7.54 times, which was 9% more than that of the control cultivar. The average yield of “Munpyeong” was 1.93 ton/ha, which was 21% more than that of the control cultivar “Owool” (Cultivar registration number: 5878).

A cowpea cultivar ‘Okdang’ (Vigna unguiculata L. Walp) was developed by the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2013 using the breeding method of pure line isolation applied to the foundation stock of IT45384. ‘Okdang’ has an erect plant type with an intermediate plant habit, green hypocotyls, heart leaflet, orange yellow seed surface of faint luster, and brown and straight pods when matured. Its first flowering and maturing dates were approximately seven and ten days earlier than that of the control cultivar ‘Seoweon’. The stem length of ‘Okdang’ was 42 cm, which was 57 cm shorter than that of the control cultivar. Its 100-seed weight was 16.6 g, which was heavier than that of the control cultivar by 5.9 g. The weight ratio of the seed coat for the entire seed was 12%, which was 1.4%p lower than that of the control cultivar. Its field resistance to leaf and systemic diseases was as strong, or slightly weaker than that of the control cultivar. In addition, ‘Okdang’ had a high lodging resistance. The average yield of ‘Okdang’ was 1.85 ton/ha, which was 40% higher than that of the control cultivar ‘Seoweon’ (Cultivar registration number: 5879).
