BACKGROUND
Fruit quality traits (i.e fresh weight, dry weight, soluble solids content, titratable acidity and firmness), the content of bioactive compounds (phenolics compounds) as well as the total antioxidant activity were evaluated in four commercial cultivars of peaches (Greta, Ufo 4, Rome Star and Ufo 6) and four of nectarines (Neve, Planet 1, Maria Carla and Mesembrina) that differ in fruit shape (standard or flat) and flesh colour (white or yellow), important cultivar of the Italian and foreigner market. The higher fruit organoleptic quality and nutritional profile of flat peach and nectarine cultivars make them candidates for exploiting new market opportunity and the chance to improve profits of farmers.

RESULTS
Results showed that assayed quality parameters differed largely among cultivars. In particular, flesh color and fruit shape accounted for most of variation in traits underlying organoleptic and nutritional quality.

CONCLUSION
Overall data suggested that the flat white-fleshed nectarine Planet 1, the yellow-fleshed nectarine Mesembrina and yellow-fleshed peach Ufo 6, because of their profiles in term of soluble solids content, titratable acidity and bioactive compounds have the greatest potential to meet consumer current requirements.
