1. A Solanum lycopersicum plant comprising a recombinant chromosomal segment on chromosome 11, wherein said chromosomal segment comprises a tomato chlorosis virus (ToCV) resistance allele from Solanum chilense that confers to said plant an increased resistance to ToCV compared to a plant not comprising said allele, wherein said ToCV resistance allele is comprised within a genomic region flanked by marker locus M1 (SEQ ID NO:6) and marker locus M3 (SEQ ID NO:16) in said chromosomal segment, and wherein:
(a) said chromosomal segment lacks an allele genetically linked to said ToCV resistance allele that confers cold sensitivity when present in a Solanum lycopersicum plant of the same genotype; or
(b) said chromosomal segment further comprises a Fusarium oxysporum f. sp. lycopersici (Fol) race 2 resistance allele from Solanum pimpinellifolium that confers to said plant increased resistance to Fol race 2 compared to a plant not comprising said allele, wherein said Fol race 2 resistance allele is comprised within a genomic region flanked by marker locus M4 (SEQ ID NO:1) and marker locus M1 (SEQ ID NO:6) in said chromosomal segment, and wherein said Fol race 2 resistance allele is in cis linkage with said ToCV resistance allele,
wherein a representative sample of seed comprising said chromosomal segment flanked by marker locus M1 and marker locus M3 has been deposited under NCMA Accession No. 202007005.
