The invention relates to aplant comprising in its genome QTLs confering to the plant an improved phenotype corresponding to foliar and/or fruit tolerance and/or resistance to Tomato Brown Rugose Fruit virus, with respect to a corresponding plant devoid of said QTLs, and wherein said QTLs are chosen from those present in the genome of a plant of the seeds HAZTBRFVRES1 NCIMB accession number 42758. The QTL are preferably characterized by defined alleles of different SNPs on chromosome 6, 9 and 11. The invention is also directed to parts of these plants with improved phenotype, as well as progeny, to the use of these plants for introgressing the improved phenotype in another genetic background, as well as to different methods for obtaining tomato plants or seeds with increased foliar and/or fruit tolerance or resistance to Tomato Brown Rugose Fruit virus.

Tolerance in plants ofto thetomato brown rugose fruit virus (TBRFV)

The invention relates to aplant 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.
