The present invention relates to an allele designated alpha-WOLF 26 which confers resistance to at least onef. sp.race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that may comprise in its amino acid sequence: a) the motif 'MAEIGYSVC' SEQ ID NO: 1 at its N-terminus; and b) the motif 'KWMCLR' SEQ ID NO: 2; and wherein the LRR domain of the protein has in order of increased preference at least 91%, 91.5%, 92%, 92.5%, 93%, 93.5%, 94%, 94.5%, 95%, 95.5%, 96%, 96.5%, 97%, 97.5%, 98%, 98.5%, 99%, 99.5%, 100% sequence identity to SEQ ID NO: 10. The allele when present in a spinach plant confers complete resistance to at leastf. sp.race Pfs:7, Pfs:10, Pfs:11, Pfs:12, Pfs:13, Pfs:14, Pfs:15, Pfs:16, Pfs:17, and does not confer resistance to downy mildew race Pfs:8 and Pfs:9.

resistance in

The invention relates to a lettuce plant (L.) which may comprise a resistance allele which confers a broad spectrum resistance to, wherein the resistance allele is located on linkage group 9, and which resistance allele is as found in the genome of plants grown from seeds of which a representative sample was deposited under accession number NCIMB 42141. The invention further provides seeds, progeny, propagation material and food products from the plant.

resistant plants

The present invention relates to an allele designated alpha-WOLF 27 which confers resistance to at least onef. sp.race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that may comprise in its amino acid sequence: a) the motif 'MAEIGYSVC' SEQ ID NO: 1 at its N-terminus; and b) the motif 'KWMCLR' SEQ ID NO: 2; and wherein the LRR domain of the protein has in order of increased preference at least 95%, 95.5%, 96%, 96.5%, 97%, 97.5%, 98%, 98.5%, 99%, 99.5%, 100% sequence similarity to SEQ ID NO: 10. The allele when present in a spinach plant confers complete resistance to at leastf. sp.race Pfs:7, Pfs:8, Pfs:9, Pfs:11, Pfs:12, Pfs:13, Pfs:14, Pfs:15, Pfs:17.
