Garden eggs are important economic vegetable crops which serve as excellent source of food with high Vitamin C content. The effect of gamma radiation (0, 1, 2, 3 kGy), packaging (polyethylene) and storage (0,1,2,3,4 weeks at 29±1ºC) on the Vitamin C content of three varieties of garden eggs (Solanum aethiopicum GH 8772 and Solanum aethiopicum GH 8773, and Solanum torvum) were studied. Irradiation was done using a cobalt-60 source and the Vitamin C content of the samples were determined by the method of Ciancaglini et al (2001). The effect of gamma irradiation (1 - 3 kGy) on Vitamin C content of the three varieties of garden eggs was not uniform. Packaging with polythene decreased the content of Vitamin C in fruits of Solanum torvum but not those of Solanum aethiopicum L. [GH 8772 and GH 8773]. Storage period decreased the Vitamin C content of packaged samples of all three varieties of garden eggs.
