Development of sequence characterized amplified region (SCAR

Striga gesnerioides race 1 (SG1) resistance gene Rsg-2-1 in cowpea (Vigna unguiculata L.) was isolated by polyacrylamide gel electrophoresis, cloned, and its nucleotide sequence determined. Based on the resulting sequence information, a pair of sequence specific primers were designed and used to isolate

Keywords: Agrobacterium rhizogenes, Composite plants, Hairy roots, Resistance, Striga gesnerioides, Witchweed Background Cowpea (Vigna unguiculata L. Walp.) is the most im-portant grain legume grown in sub-Saharan Africa [1,2]. Approximately 12.5 million tons of cowpea grains are produced worldwide each year with a majority (over


the various cowpea accessions studied (Table Colour of flowers and pods Most of the cowpea accessions produced mauve or purple flower colours. Nevertheless, GH3684 C 2 L 4 P 8, GH7185 1BLK L 4 P 1, and IT97K-499 -35 had white flower. Most of the pods of the cowpea accessions (53 %) at maturity were purplish green in colour including GH3684A 2,
