Estimating the term…
The present invention relates to downy mildew, and especially downy mildew caused by the plant pathogen Peronospora farinosa, resistant spinach plants (Spinacia oleracea). The present spinach plants include a downy mildew resistance providing genomic fragment from Spinacia tetrandra. Specifically, the present invention relates to spinach plants being resistant to downy mildew, wherein the spinach plant includes a downy mildew resistance providing genomic fragment from Spinacia tetrandra such as spinach plants including in their genomes one or more nucleic acid sequences selected from the groups consisting of SEQ ID No. 1, SEQ ID No. 3, SEQ ID No. 5, SEQ ID No. 7, SEQ ID No. 9, SEQ ID No. 11, SEQ ID No. 13, SEQ ID No. 15, SEQ ID No. 17, SEQ ID No. 19, SEQ ID No. 21, SEQ ID No. 23, SEQ ID No. 25, SEQ ID No. 27, SEQ ID No. 29, SEQ ID No. 31, SEQ ID No. 33 and SEQ ID No. 35.
A hybrid Spinacia oleracea plant being resistant to downy mildew and comprising in its genome, on chromosome 4 thereof, a nucleic acid fragment from S. tetrandra comprising a downy mildew resistance locus comprising SEQ ID NO:
A method for providing spinach plant being resistant to downy mildew comprising introgressing a nucleic acid fragment from chromosome 4 of Spinacia tetrandra into a S. oleracea plant, the nucleic acid fragment comprising a downy mildew resistance locus comprising SEQ ID NO:
