The present invention relates to a plant with a copy number variation (CNV) of a 9-LOX5 gene, wherein the CNV has at least 2 copies of a 9-LOX5 gene, wherein the 9-LOX5 gene comprises SEQ ID NO: 1, or a sequence having at least 60% sequence identity to SEQ ID NO: 1, and wherein the presence of the CNV leads to powdery mildew resistance in the plant. The invention further relates to nucleic acid molecules, methods for selecting powdery mildew resistant plants, the plants thus obtained therefrom, and seeds and parts thereof.

9-LOX5 gene variant providing powdery mildew resistance

The present invention relates to aplant which comprises a copy number variant region which leads toandresistance. The invention further relates to propagation material suitable for producing suchplant. The invention also relates to a method for producing suchplant and to methods for identification and selection of such a plant. In addition, the invention relates to a marker for identification of the copy number variant region resulting inandresistance in, and to use of said marker. The invention also relates to seed which comprises the copy number variant region which leads toandresistance in the plant grown from such seed.

Genetic basis forresistance

The present invention relates to aplant which may comprise a QTL, a copy number variant region, at least two copies of an ERF gene, or a mutation leading to increased expression of an ERF gene, which leads toresistance. The invention further relates to propagation material suitable for producing suchplant. The invention also relates to a method for producing suchplant and to methods for identification and selection of such a plant. In addition, the invention relates to a marker for identification of the QTL or copy number variant region, or for identification of the presence of at least two copies of an ERF gene resulting inresistance in, and to use of said marker. The invention also relates to seed which may comprise the QTL, copy number variant region, at least two copies of an ERF gene, or a mutation leading to increased expression of an ERF gene, which leads toresistance in the plant grown from such seed.
