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)
