Unlocking the European traditional tomato genetic resources

The Mediterranean basin countries are considered secondary centres of tomato diversification. However, information on phenotypic and allelic variation of local tomato materials is still limited. To unveil the molecular basis of Southern European tomato phenotypic diversity, we carried out the most comprehensive phenotypic and genomic variability analysis on traditional European tomato by using 1) a collection of 1,499 traditional European tomatoes (TRADITOM collection) and 2) a multipurpose core collection (TCC), comprising 227 European traditional tomato accessions from the original TRADITOM collection, that captured most of genotypic and phenotypic variation and geographical origin present in traditional tomatoPostprint (published version
