Provided herein are Erysiphe necator resistance conferring genes, plants, plant parts and seeds comprising the present resistance providing genes and the use thereof for selecting Erysiphe necator resistant plants. Specifically, provided herein are Erysiphe necator resistance conferring genes, wherein the amino acid sequence encoded by said resistance conferring genes is the primary amino acid sequence represented SEQ ID No. 1, or a primary amino acid sequence with more than 70% identity, preferably more than 80% identity, more preferably more than 90% identity, and most preferably more than 95% identity with SEQ ID No. 1； and wherein said resistance conferring gene is impaired.
