Estimating the term…
The invention relates to a Brassica plant that is resistant to Hyaloperonospora brassicae, which plant may comprise a QTL on chromosome 8, and optionally a QTL on chromosome 4, and/or a QTL on chromosome 1. The presence of the QTL on chromosome 8 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 1 to 7; the presence of the QTL on chromosome 4 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 8 to 16; and the presence of the QTL on chromosome 1 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 17 to 22. The QTL is as comprised in the genome of a Brassica plant representative seed of which was deposited with the NCIMB under accession number NCIMB 43346.
A Brassica plant that is resistant to Hyaloperonospora brassicae, comprising a QTL on chromosome 8 which confers resistance to Hyaloperonospora brassicae to the Brassica plant.
A Brassica seed comprising a QTL on chromosome 8 and optionally a QTL on chromosome 4 and/or a QTL on chromosome 1, wherein the QTL confers resistance to Hyaloperonospora brassicae to the Brassica plant.
A cell of a resistant Brassica plant showing resistance to Hyaloperonospora brassicae, which cell comprises a QTL on chromosome 8 and optionally a QTL on chromosome 4 and/or a QTL on chromosome 1.
A tissue culture of a Brassica plant shows resistance to Hyaloperonospora brassicae, that can be regenerated into a Brassica plant with shows resistance to Hyaloperonospora brassicae, which tissue culture comprises a QTL on chromosome 8 and optionally a QTL on chromosome 4 and/or a QTL on chromosome 1.

A method of selecting a Brassica plant showing resistance to Hyaloperonospora brassicae, comprising identifying the presence of the QTL on chromosome 8, and optionally the QTL on chromosome 4 and/or the QTL on chromosome 1, and selecting a plant that comprises the QTL on chromosome 8, and optionally the QTL on chromosome 4 and/or the QTL on chromosome 1 as a Brassica plant showing resistance to Hyaloperonospora brassicae.
Method for producing a Brassica plant showing resistance to Hyaloperonospora brassicae, comprising introducing a QTL on chromosome 8 and optionally a QTL on chromosome 4 and/or a QTL on chromosome 1 in a Brassica plant.
