Abstract

In peach fruits, phenolic compounds serve as a major source of potential antioxidants which are known to play a significant role in fruit quality and in human well being. This study was conducted in a F1 population derived from the cross ‘Venus’ × ‘Big Top’ nectarines in order to investigate the variability in the fruit antioxidant content and to study the genetic control and location of QTLs involved in fruit quality traits. Biochemical analyses have been performed to measure L-ascorbic acid (vitamin C), total phenolics, flavonoids, anthocyanins contents and antioxidant capacity.

This study was funded by the Spanish MIC1NN (Ministry of Science and Innovation) grant AGL-2008-00283, cofunded by FEDER, and the Regional Government of Aragon (A44). W. Abidi was supported by a JAE fellowship from CSIC (Consejo Superior de Investigaciones Científicas).
