Assessing the resistance levels of wheat germplasms and understanding the genetic underpinnings of this resistance is crucial. In this study, we evaluated the seedling resistance to powdery mildew in 558 wheat accessions, along with the presence of resistance genes <em>Pm1</em>, <em>Pm2</em>, <em>Pm4</em>, <em>Pm5</em>, <em>Pm6</em>, <em>Pm8</em>, <em>Pm12</em>, <em>Pm21</em>, <em>Pm24</em>, <em>Pm41</em>, <em>Pm42</em>, <em>Pm45</em>, <em>Pm47</em>, <em>Pm60</em>, and <em>Pm69</em> using various <em>Bgt</em> isolates and associated diagnostic markers.
