Comparison of the fruit characteristics (fresh weight, color, firmness, acidity, sugar content) of transgenic fruit compared to non-transgenic fruit (Galaxy) over a period of seven years. Fruit firmness was determined by a penetrometer and is reported in units of Kg/cm2. The acidity index is g/L. Sugar content was measured as degrees Brix or the fraction of sugar per hundred parts aqueous solution, by mass. Stars (x) represent cases where measurements were not taken, in 1999, due to a low number of available fruit and in 2006 (xx), due to the elimination of the trees from the orchard.
