It was used data of grain yield of cowpea from four environments in Ceara, testing 22 genotypes, and using the following methods: Traditional, Plaisted and Peterson, Wricke, Finlay e Wilkinson, Eberhart and Russell, Linn and Binns, and Annicchiarico. We recommend using the methods Annicchiriaco and Linn and Bins together with the method of Eberhart and Russell. The genotypes CE-31, CE-73, CE-77, CE-949 and CE-956 are the most adapted and stable. The latter two are suitable for cultivation in production system with more technology.
