RESISTANCE IN PLANTS OF SOLANUM LYCOPERSICUM TO THE TOBAMOVIRUS TOMATO BROWN RUGOSE FRUIT VIRUS

摘要

The invention relates to a Solanum lycopersicum plant resistant to Tomato Brown Rugose Fruit virus comprising in its genome the combination of the Tm-1 resistance gene on chromosome 2, and at least one quantitative trait locus (QTL) chosen from QTL3 on chromosome 11, QTL1 on chromosome 6 and QTL2 on chromosome 9, that independently confer to the plant foliar and/or fruit tolerance to TBRFV, wherein said QTLs are present in the genome of a plant of the seeds HAZTBRFVRES1 NCIMB accession number 42758. The combination of at least one of these QTLs with the Tm-1 gene delays, reduces or inhibits the replication or multiplication of the virus in the plants of the invention. The invention is also directed to parts of these plants with TBRFV resistance phenotype, as well as progeny, to the use of these plants for introgressing the resistance in another genetic background, as well as to different methods for obtaining tomato plants or seeds with increased resistance to Tomato Brown Rugose Fruit virus.
