Abstract: In order to obtain new monoecious lines of Cucumis melo, the hy brids between monoecious and andromonoecious were made.Monoecious NI Ls w ere derived from these hybrids through three pathways.Inheritance of sex expression was investigated throug h hy brids between monoecious NILs and different genotype of melons.Results showed that monoecious and andromonoecious segregated in the ratio of 3:1 in four F2 generations including Mr and Mm, Ym, YF, F-Y lines.Moreover, backcrossing wi th Mm and Ym, a ratio that monoecious: andromonoecious =1:1 was observed.These suggested that monoeciousness is under the control of a single dominant A allele.Four monoecious lines have been developed through continuous backcrossing with advanced breeding lines from different geno types, self-crossing and selection at the final step, as well as through continuous self-crossing and selection of hybrid progenies.

Key words: Melon, Monoecious, Genotype, Crossing, NILs
