The development of varieties with a high content of antioxidant compounds, such as
carotenoids, has become a major focus in the marketing of tomato. Several mutants have been
used in the development of high pigment varieties, but the significant influence of the environment
on carotenoid content and the presence of negative side effects in vegetative growth and
yield have limited the success of these variants. Consequently, the identification of alternative
sources of variation in the quest for high carotenoid content is ongoing. In this study, 12 accessions
of Solanum lycopersicum (including the former var cerasiforme) and S. pimpinelifolium
have been evaluated in three different environments: open field and glasshouse cultivation at
two sites. Three accessions (BGV6195 of S. pimpinellifolium, LA1423 of the former var cerasiforme
and LA3633 a possible hybrid between S. pimpinellifolium and S. lycopersicum) showed
outstanding and stable lycopene content, that doubled in all three environments the content
of the positive control LA3538, with the high pigment-1 mutation (hp1). In addition, accession
CATIE14812 would also be interesting as regards improvement of β-carotene content. These
materials offer new opportunities in the development of tomato varieties with enriched and reliable
carotenoid content and the close taxonomic relationship of these accessions with cultivated
tomato will facilitate their use in breeding programs [-]
