Abstract: Melon is one of the main fruits of the world, and the main objective for melon breeders is to breed new varieties with high quality. To improve the efficiency of melon hybrid combinations, the combining ability and heritability for mainly characters of melon fruit were analyzed by 28 cross combinations which were made with 8 melon inbred lines by the method of Griffing (IV). Except for vertical diameter of fruit, the other six characters of melon fruit including diameter of fruit heart chamber, horizontal diameter of fruit, vertical diameter of fruit, flesh thickness, soluble sugar at center and edge were significantly different between the inbred lines. And A1, A3 and A4 showed the high general combining ability (GCA) effect value in fruit weight, diameter of fruit heart chamber, horizontal diameter of fruit and flesh thickness, while A2, B1, B2, B3 and B4 showed the high GCA effect value in fruit sugar at flesh center and edge. A1×A2, A1×B3, A3×B2 and A3×B3 were the excellent hybrid combinations with high special combining ability (SCA). Our results provided reliable basis for selecting proper parental lines in cross breeding of melon.
