Spanish traditional tomato. Effects of genotype, location and agronomic conditions on the nutritional quality and evaluation of consumer preferences.

Traditional tomatoes are highly valued for their organoleptic quality and cultural links with a territory. At present, strong competition has put these crops at risk, and it is necessary to differentiate the local cultivars and improve their nutritional value. This work focused on the nutritional study of four selected lines of a local tomato grown in two locations and in two agronomic conditions to nutritionally characterize the tomatoes and to study the effect of location and cultivation on nutritional parameters. Data on nutritional characterization revealed significant effects of location and treatment in most compounds. Tomatoes grown in traditional areas showed a significantly higher concentration of some phenolic acids and beta-carotene. Lycopene contents were not location dependent. The open field test showed significant differences in all the components. Regarding the best nutritional genotypes, all the components were dependent on lines, and significant differences were confirmed between them.
