GENETIC BASIS FOR PYTHIUM RESISTANCE

摘要

The present invention relates to a Cucumis sativus plant comprising 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 to Pythium resistance. The invention further relates to propagation material suitable for producing such Cucumis sativus plant. The invention also relates to a method for producing such Cucumis sativus plant 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 in Pythium resistance in Cucumis sativus, and to use of said marker. The invention also relates to seed comprising 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 to Pythium resistance in the plant grown from such seed.
