BREEDING OF BLACKEYE COWPEA FOR ALECTRA VOGELII RESISTANCE

One of the constraints to cowpea production in Botswana is the incidence of a parasitic weed Alectra vogelii L. Benth, one of the Scrophulariaceae family. It causes substantial damage by attaching itself onto the cowpea plant and tapping nutrients from it. This causes sever grain yield reductions. Blackeye variety is highly susceptible for this parasite. Yield losses of up to 100% have been recorded in farmer’s fields in some agricultural regions. It was therefore, deemed necessary to embark into a breeding program to insert the genes for Aletra resistance into Blackeye cowpea. With Alectra vogelii resistant Blackeye, all cowpea farmers will be able to grow and obtain high yields even in fields with high seed banks of the weed.
