Conteúdo: | Thirty geographically diverse cowpea (Vigna unguiculata (L.) Walp.) genotypes were grouped into four clusters, on the basis of multivariate analysis, for seven yield component characters. Characters like pods per plant, seeds per pod, and seed yield per plant were found to contribute much to the genetic divergence in cowpea. The clustoring pattern revealed the absence of parallelism between geographic and genetic diversity. Inter-cluster distances and mean cluster character values indicated that hybridization of cluster I genotypes that have a higher mean yield with a cluster IV genotype would exhibit high heterosis and likely result in segregants with higher yield.
