Powdery mildew (PM) of wheat caused by Blumeria graminis f. sp. tritici is among the most important diseases, causing significant yield and quality losses in many countries worldwide. Considerable progress has been made resistance breeding to mitigate powdery mildew. Genetic host employs either race-specific (qualitative) resistance, race-non-specific (quantitative), or a combination both. Over recent decades, efforts identify traits have led discovery over 240 genes quantitative trait loci (QTLs) across all 21 chromosomes. Sources PM include landraces, synthetic, cultivated, wild species. The identified various genetic resources transferred elite background well-adapted cultivar with minimum linkage drag using advanced selection approaches. In this effort, landraces emerged as an source allelic diversity, which highly valuable for developing new PM-resistant cultivars. However, not characterized limiting their use programs. polygenic trait; therefore, degree such mostly influenced environmental conditions. Another challenge lack consistent disease pressure multi-environment trials, compromises phenotypic efficiency. It therefore imperative complement conventional technologies molecular improve High-throughput genotyping techniques, based on chip array sequencing, increased capacity basis resistance. cultivars still challenging, there need harness potential approaches accelerate progress. main objective review describe status well latest discoveries that offer novel ways achieve durable Major topics discussed wheat, available adult-plant PM, gene banks, complimentary approaches, emphasis marker-assisted (MAS).
