The invention relates to a Solanum lycopersicum plant 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.
