Abstract:

To explore the difference of fruit quality in different ploidy melon, 2 melon cultivars including their different ploidy (diploid, triploid crossed with 4X×2X and autotetraploid induced by colchicine)were selected for text their soluble sugar, central soluble solids，soluble protein and Vc contents. The results showed that the soluble sugar, central soluble solids, soluble protein and Vc content were divergent in different ploidy melon as follows: soluble sugar, central soluble solids and soluble protein contents made the same trend, 3x>4x>2x; Vc contents,4x>3x>2x.
