Abstract: ‘Pesca di Bivona’, ‘Murtiddara’, ‘Bianca’, ‘Agostina’ and ‘Settembrina’ are non-melting white flesh peach landraces characterized by a persistent aroma and excellent flavour highly appreciated by Italian consumers. The aim of this work was to assess the persistence of their quality and sensory profi les after storage at 0°C for 28 days, using destructive and non-destructive analyses. The IAD index, measured either at harvest or at fruit removal from cold storage, was correlated to TSS, TA and firmness of all the landraces. ‘Settembrina’ and ‘Agostina’ harvested at the commercial ripening time (50.5 ± 4.3 N) and stored at 0°C during 4 weeks kept harvest quality in terms of sensorial attributes, fl esh fi rmness, chlorophyll content, TSS, TA and reduced weight loss.
