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). KCI Citation Count: 2
