Descripción:	The aim of the present study is to estimate the adaptability and stability of K and Ca contents, and grain yield in cowpea lines for release as new cultivars. Forty-four inbred lines and cultivars were assessed in seven sites of the Brazilian semi-arid region. Significant statistical differences were observed in the treatment, environments and environment treatment interaction mean squares for all variables. The methods by Eberhart and Russell (1966), Lin and Binns (1988), and the additive main effects and multiplicative interaction (AMMI) showed similar results in the selection of superior materials. The C4I and C3O lines showed grain yield equal to or greater than the overall mean of 1050 kg ha-1 in the experiments, with mean of K and Ca higher than the values of the assessed cultivars, as well as wide stability and good predictability in the assessed environment series. The lines showed great potential to be released as new cultivars in the Brazilian semiarid region.
