The chironja (Citrus sinensis L. Osbcek*Citrus paradisi Macf.) is a citrus hybrid of excellent quality. Attempts at commercialization has been limited by the susceptibility of the fruit to rapid rind breakdown after harvest. A study was undertaken to determine the effects of postharvest calcium chloride (CaCl2) dips and lipid waxes on rind quality of two chironja clones at two maturity stages. CaCl2 dips had no significant effect on weight loss irresponsible of clones and maturity. Waxing improved lustre of fruits. retarded aging and shrinkage and slightly inhibited degreening. Pac Rite wax was more effective than Prima Fresh wax. Clone 2-4 was less resistant than clone 3-8 to rind breakdown and made better use of the wax treatments. Mature yellow fruits had a better response to treatments than mature green fruits in retarding weight loss. Untreated fruits deteriorated rapidly after five days. Symptoms of rind breakdown were incipient in calcium treated fruits. Preharvest calcium applications and/or postharvest waxing may reduce the incidence of rind breakdown in the chimnja.
