The commercial quality of yellow melon 'Gold Mine' and 'Gold Pride' hybrids at different harvest times was examined. The fruits were harvested in the MossoróAssu agricultural pole, Rio Grande do Norte State, Brazil, being kept under 11±1ºC and 90±5% relative humidity, during 28 days. A 5 x 5 factorial scheme in a completely randomized design was used with five replications and one fruit per plot. The first factor was recorded at harvest time (0; 2; 4; 6 and 8 days retardation of the harvest) and the second at the storage periods (0; 7; 14; 21 and 28 days). We evaluated the flesh firmness (N), weight loss (%), internal and external appearances and soluble solids content (%). The flesh firmness and the internal appearance were strongly influenced by the harvest delay, providing fruits with internal disorder and smaller flesh resistance. The harvest delay influenced significantly the weight loss of the Gold Mine hybrid with larger weight losses occurring after 21 days of storage in treatments where the harvest was delayed 4 and 6 days. The harvest delay induced larger susceptibility to chilling injury in both hybrids and increased the soluble solids content in the hybrid Gold Pride.
