Abstract: In this study, 51 cowpea genotypes were tested for tissue culture and shoot induction in Agrobacterium-mediated transformation. After a preliminary screening for regeneration, the rate of shoot regeneration was graded and 10 genotypes with a regeneration rate above 80% were tested further in three replicates. White August Cowpea was found to show the highest reproduction coefficient and induction rate of adventitious buds, which were 1.93 and 86.40%, respectively. Therefore, this genotype may be used as a good explant source in the future transgenic studies.

Key words: cowpea, genotype, Agrobacterium tumefaciens, regeneration rate
