Genotype-specific radiosensitivity and mutagenic dose optimization in Ghanaian cowpea ( <i>Vigna unguiculata</i> ): a case study of cowpea cultivar Videza and Songotra

2026University of Ghana

Abstract

Our findings provide practical, cultivar-specific dose benchmarks for cowpea mutation breeding. Based on <i>LD</i><sub>50</sub><i><sup>G</sup></i>, <i>LD</i><sub>50</sub><i><sup>S</sup></i>, and <i>RD</i><sub>50</sub><i><sup>H</sup></i> values, we recommend gamma irradiation doses of 200-250 Gy for Videza and 250-300 Gy for Songotra to maximize mutation induction while maintaining seed viability. These guidelines support the development of improved cowpea varieties for enhanced food security and agricultural resilience.
