Historically, conventional breeding has been the primary strategy used to develop a number of Striga-resistant varieties currently grown in the Sahel of Western Africa. In this study, we have successfully developed and applied a marker-assisted selection strategy that employs a single backcross p...

Genetic diversity was investigated among fifty accessions of yard-long-bean (Vigna unguiculatasubspecies unguiculatacultivar group sesquipedalis) using simple sequence repeat (SSR) markers. Sixteen SSR primers were used to amplify DNA of the 50 accessions. A total of 63 polymorphic bands were det...

The genetic diversity in wild cowpea was assessed using cowpea derived simple sequence repeat (SSR) markers. A total of forty eight wild cowpea lines collected from diverse geographical locations in Africa were used for the study. Twelve SSR markers were selected for amplification of DNA of the t...

Forty eight accessions of cultivated cowpea were assessed using 12 simple sequence repeat (SSR) markers. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram constructed revealed three main clusters when truncated at 65% similarity coefficient. All accessions showed high genet...
