Ten cultivarsof cowpea grown in the screen house facility at Botanical garden, University of Ilorin, Nigeriawereevaluated for genetic similarity and variability. Data were collected on vegetative,fruiting and seed characters. Proximate analysis was conducted to determine variation in nutrient composition of the seeds at harvest. The results showed considerable variations in growth and yield characters evaluated. Cultivars NGB/06/047, IFE BROWN 2012 and IT98K-133-1-1 had optimal growth… Expand
