TBRFV resistant tomato plant
The invention relates to a Solanum lycopersicum plant that is resistant to TBRFV, which plant comprises a QTL on chromosome 11 between SEQ ID NO: 1 and 53. The presence of the QTL on chromosome 11 is identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 4 to 52. The QTL is as comprised in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890.
1. A Solanum lycopersicum plant that is resistant to Tomato brown rugose fruit virus (TBRFV),
which plant comprises a QTL on chromosome 11,
wherein the QTL on chromosome 11 is located between SEQ ID NO: 1 and SEQ ID NO: 53, and
wherein the QTL on chromosome 11 is linked to a marker represented by SEQ ID NO. 10, and the QTL is as present in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890.
2. A Solanum lycopersicum plant as claimed in claim 1 , wherein the QTL is flanked by SEQ ID NO: 4 and SEQ ID NO: 52 in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890.
3. A cell of a TBRFV resistant Solanum lycopersicum plant as claimed in claim 1 , which cell comprises the QTL as defined in claim 1 on chromosome 11 in its genome.
4. A Solanum lycopersicum seed, wherein a plant grown from the seed is resistant to TBRFV due to the presence in its genome of the QTL on chromosome 11 as defined in claim 1 .
5. A propagation material suitable for producing a Solanum lycopersicum plant as claimed in claim 1 ,
wherein the propagation material is suitable for sexual reproduction, vegetative reproduction or for tissue culture of regenerable cells,
wherein the plant produced from the propagation material comprises the QTL that leads to TBRFV resistance on chromosome 11, as defined in claim 1 .
6. The propagation material of claim 5 , wherein the propagation material suitable for sexual reproduction is selected from the group comprising a microspore, pollen, an ovary, an ovule, an embryo sac, and an egg cell.
7. The propagation material of claim 5 , wherein the propagation material suitable for vegetative reproduction is selected from the group consisting of a cutting, a root, a stem, a cell, and a protoplast.
8. The propagation material of claim 5 , wherein the propagation material suitable for tissue culture of regenerable cells is selected from the group comprising a leaf, pollen, an embryo, a cotyledon, a hypocotyl, a meristematic cell, a root, a root tip, an anther, a flower, a seed, and a stem.
9. A method for identifying TBRFV resistance in a Solanum lycopersicum plant comprising identifying a marker represented by SEQ ID NO: 10 in the plant.
10. A method for producing a TBRFV resistant Solanum lycopersicum plant comprising introducing a QTL as defined in claim 1 on chromosome 11, in a S. lycopersicum plant.
11. A method for selecting a TBRFV resistant Solanum lycopersicum plant, comprising identifying the presence of a QTL as defined in claim 1 on chromosome 11, and selecting a plant that comprises said QTL as a TBRFV resistant plant.
12. The method as claimed in claim 11 , wherein identifying the presence of the QTL on chromosome 11 is with a marker selected from the group consisting of SEQ ID NOS: 4 to 52.
13. A method for the production of a Solanum lycopersicum plant which is resistant to TBRFV, said method comprising:
a) crossing the plant as claimed in claim 1 comprising the QTL on chromosome 11 with another plant;
b) optionally performing one or more rounds of selfing and/or crossing of the plant resulting from the cross in step a) to obtain a further generation population;
c) selecting from the plant resulting from the cross in step a), or from the further generation population of step b), a plant that comprises the QTL on chromosome 11, as defined in claim 1 , which plant is resistant against TBRFV,
wherein selection of a plant comprising the QTL on chromosome 11 is with a molecular marker genetically linked to the QTL, which marker is represented by SEQ ID NO: 10.
14. The method as claimed in claim 13 , wherein the plant which is resistant to TBRFV is phenotypically selected.
15. The method as claimed in claim 13 , wherein the plant comprising the QTL from chromosome 11 from step a) is a plant grown from seed deposited under NCIMB accession number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890, or a progeny plant thereof.
16. A method for the production of hybrid Solanum lycopersicum seed comprising
crossing a first parent plant with a second parent plant and
harvesting the resultant hybrid seed,
wherein the first parent plant and/or the second parent plant is a plant of the invention that is resistant to TBRFV comprising the QTL as defined in claim 1 on chromosome 11,
wherein the presence of the QTL leads to resistance to TBRFV in the hybrid plant that is grown from the seed.
17. The hybrid Solanum lycopersicum seed produced by the method as claimed in claim 16 .
