Abstract
Tomato has been identified as a fruit of great interest because of its high content of health-related compounds.
Unfortunately, modern agriculture focuses its efforts on prioritizing characteristics such as high yield, long life and visual impact, neglecting organoleptic and nutritional quality.
In this sense, local landraces cover a wide genetic diversity that can help mitigate the current genetic erosion within agricultural diversity, increasing nutritional and organoleptic traits compared to commercial F1. Thus, the objective of this work was to measure the response of 15 traditional tomato genotypes within and across environments for flavonoid (flavonols and flavanones) and hydroxycinnamic acid content to determine genotypes that are stable in four environments.
Estimated variance components were calculated for each genotype, environment, and genotype-by-environment interaction.
In our work, significant differences were observed among the genotypes and among genotype-by-environment interactions.
Among the genotypes in each environment, the within-genotype variances were also significantly different.
When the nature of the genotype-by-environment interaction was examined, changes in genotype rank and differences in magnitude were observed.
In addition, when interactions were analyzed by tomato type, the cherry type showed the greatest stability across environments with respect to flavonol and hydroxycinnamic acid content.
