In this study we investigated the influence of genetics, environment and cultivation procedures in determining the chemical composition of tomato fruit. For this purpose a breeding population of cultivated tomatoes consisting of multiple lines each of which possess a minor proportion of the genome of a wild species tomato. These lines were grown in the field in Avignon (France) for two consecutive seasons under two different cultivation conditions: one in which the fruit were allowed to develop naturally and another in which the fruit load was artificially reduced to one per plant branch. In all cases samples were taken for chemical analysis using gas-chromatography mass-spectrometry. The results of this study were highly informative since they suggested that whilst genetic factors were still important the influence of the environmental and cultivation conditions on chemical composition were of greater importance. As such this work has considerably advanced our understanding of the chemical composition of fruits and by implication their nutritional value and will likely prove a strong basis on which breeding companies can hope to improve human circumstance.
