This research was carried out in 2006 & 2007, using three peach cultivars, i.e., Flordaprince, Desert Red and Meet Ghamr to determine fruit maturity. Fruit weight, skin and flesh colour (a) values were gradually increased during maturation. In Meet Ghamr skin (b) values were increased till the age of 121 days, then decreased at the age of 128 days and displayed the lowest (a/b) values. Flesh color of Desert Red was much more yellow color than that of Flordaprince, while Meet Ghamr displayed red color. Reductions in firmness and total acidity were showed with advanced stage of fruit maturity, while SSC and total sugars showed inversely trend.
