This marker based subset comprises 83 active World Vegetable Center tomato accessions selected for resistance associated DNA marker calls for tobacco mosaic virus. Selection used the supplied wet laboratory screening dataset (version 2024.1) and its accompanying descriptor metadata. An accession qualified when at least one of the relevant marker columns (Tm2-a) was coded R (Resistant). Calls coded H (Heterozygous), S (Susceptible), N (Non-detectable), or blank did not qualify on their own. Calls were trimmed of surrounding whitespace, and qualifying accessions were deduplicated across markers. This subset identifies candidates from marker evidence. It does not establish phenotypic resistance, pathogen race coverage, or field performance. It is intended to support targeted germplasm evaluation and selection of material for resistance research.
