Diallelic analysis to obtain cowpea (Vigna unguiculata L. Walp.) populations tolerant to water deficit

Authors: E.V. Rodrigues, K.J. Damasceno-Silva, M.M. Rocha and E.A. Bastos

The purpose of this study was to identify parents and obtain segregating populations of cowpea (Vigna unguiculata L. Walp.) with the potential for tolerance to water deficit. A full diallel was performed with six cowpea genotypes, and two experiments were conducted in Teresina, PI, Brazil in 2011 to evaluate 30 F2 populations .. Read More»

The cowpea weevil (Callosobruchus maculatus Fabr.) is the most destructive pest of the cowpea bean; it reduces seed quality. To control this pest, resistance testing combined with genetic analysis using molecular markers has been widely applied in research. Among the markers that show reliable results, the inter-simple sequenc.. Read More»
