Abstract:
Seven thick-skinned melon materials were used as parents，of which the female unisexual flower autogamous line was the mother，and 6 single-crosses and 30 tri-crosses were formulated by incomplete biallelic hybridization，and the plant growth characteristics and fruit traits of 43 test materials were measured，and their super-parental and super-neutral dominance were studied，with a view to exploring the comparative hybrid dominance of the single-cross and tri-cross of melons formulated by the use of the female unisexual flower autogamous line.The results showed that the strong dominant combinations were No.12 (M123×M112) and No.25((M123×M113)×M141).The main traits of the single-cross hybrid had an obvious heterozygous advantage，and the tri-cross hybrid had a heterozygous advantage，but the advantage was not significant，and the variability of the two was not very different.
