Cercospora leaf spot (CLS) caused by Cercospora canescens is an important disease of cowpea (Vigna unguiculata). A previous study using an F2 population [CSR12906 (susceptible) × IT90K-59-120 (resistant)] identified a major QTL qCLS9.1 for resistance to CLS. In this study, we finely mapped and identified candidate genes of qCLS9.1 using an F3:4 population of 699 individuals derived from two F2:3 individuals segregating at qCLS9.1 from the original population. Fine mapping narrowed down the qCLS9.1 for the resistance to a 60.6-Kb region on cowpea chromosome 10.
