Abstract: A Capsicum plant resistant to powdery mildew caused by the fungal pathogen Leveillula taurica, a cell, plant part or seed of the Capsicum plant and to methods for identifying it, and the use of the plants for improving the yield of pepper production in an environment infected by Leveillula taurica and/or for limiting or controlling an infection by Leveillula taurica; wherein, the Capsicum plant includes introgressed in its genome a quantitative trait locus (QTL) conferring resistance to powdery mildew, wherein the QTL is located on chromosome 6 within the genomic interval delimited by the marker PE-0014628 (SEQ ID NO: 1) and the marker PE-0021476 (SEQ ID NO: 37).
