| الوصف: | Cowpea (Vigna unguiculata L.) improvement is necessary to increase its contribution to food and nutrition security in the impoverished regions such as the Sub-Saharan African Region. Genetic variability is fundamental to selecting parental genetic resources with agronomic and economic important traits for recombination. Gamma radiation is one of the valuable mutagens for creating novel mutant populations with allelic combinations needed to develop varieties with the desired traits. In this study, we determined the optimum dosage of gamma irradiation to use in breeding programs to enhance high yield and tolerance to field pests, including Maruca pod borers (Maruca vitrata) in locally adapted cowpea varieties. Seeds of two locally adapted cowpea genotypes (NkR1P3 and NamCp201) were treated with six gamma irradiation doses – 0 (un-irradiated), 75, 150, 300, 450, and 600 Gy. Consequently, the radio-sensitivity test was conducted in seed trays under net house conditions at the experimental field of Ogongo Campus, University of Namibia, Namibia. The study was arranged in a completely randomized design with three replications. Significant interactions (p |
