In this work there were established that the native populations of tomato present different characteristics of quality (internal and external) in relation with the commercial varieties. Likewise, the pattern of maturity of the native populations is different from that of commercial varieties and that the native populations are better accepted by the consumers. The fruits were evaluated in three states of maturity, deciding the variables of response; acidity titulable, total soluble solids, pH, vitamin C, firmness, color, concentration of CO2 and ethylene, days postharvest and acceptability. The design was completely at random with arrangement factorial and for the acceptability a design of blocks at random. Both the chemical composition and the external factors evolve as it advances the maturity of the fruit, diminishing the firmness and the life postharvest, and increasing the total soluble solids, pH, acidity, the production of CO2 and ethylene. The native populations present excellent characteristics of quality in such a way that they can compete with commercial varieties.
