ResumoNineteen cowpea genotypes from the Germplasm Bank of the Genetic Improvement Program of the Agronomic Institute of Pernambuco, Brazil (IPA) were evaluated in three locations in Northeast of Brazil, featuring edaphoclimatic characteristics of Tropical Savanna (Cerrado) and Caatinga (Semiarid) biomes.The aim of this study was to evaluate genotypes with production potential for these regions.An experimental design of randomised blocks was used, with 19 treatments (genotypes) and four replications.Six characteristics relating to yield components were studied.There was no significant difference in yield between the genotypes under evaluation for the region of Pesqueira, PE or Lajedo, PE, both in Caatinga biome.However, the studied genotypes displayed variations in yield for Balsas, MA, Cerrado region, demonstrating that this growth environment was suitable for the expression of production potential in the genotypes.The differences presented by genotypes for the characteristics under stu dy favour their recommendation, and demonstrate the possibility of their selection for genetic improvement of the species.The average yield of 840.8 kg ha -1 indicates good adaptation by the genotypes for cultivation in tropical savanna region.
