Cowpea [Vigna unguiculata (L.) Walp.] is a legume whose immature pods are consumed and marketed. However, it suffers yield losses due to attacks of aphid-transmitted mosaic disease. The present work is a study of the genetic resistance of twelve (12) varieties of vegetable cowpea to Cowpea Aphid-Borne Mosaic Virus (CABMV) at Kamboinsé. The objective of the study was to contribute to the enhancement and improvement of yields through the development of vegetable cowpea varieties resistant to CABMV. The study was conducted in a screen house at Kamboinsé research station using a randomized complete block design with three (3) replications, all inoculated with CABMV. The study showed the existence of a large genetic variability within the varieties studied. The analysis of variance showed very highly significant differences (P=0.0001) between the twelve (12) vegetable cowpea varieties in terms of symptom severity.
