The morphoagronomic diversity of 57 cowpea lines was assessed using multivariate analysis. The germplasm was evaluated in August 2009 using a randomized block design with three replications based on the following traits: number of pods per peduncle, pod length (PL), number of grains per pod (NGP), grain length (GRL), grain width, 100-grain weight (W100G), and yield. The heritability values of the traits PL, NGP, GRL, and W100G were all higher than 70%, indicating the possibility of genetic progress with selection. The crosses between the lines IT82D-889 and IT89KD-245, IT85F-1380 and IT89KD-245, and IT89KD-245 and IT98K-1092-1 could result in promising genetic combinations. The characteristics that contributed most to genetic divergence were W100G (49.7%), PL (16.7%), GRL (12.0%), and NGP (9.7%).  aMultivariate analysis  aBanco de germoplasma  aFeijao de corda  aMétodo estatístico  aVigna unguiculata  aAcessos de caupi  aCowpea accessions  aGermplasm bank1 aSILVA, K.
