Abstract Genetic analysis was carried out on P1,P2,F1,F2,BC1P1 and BC1P2 using WI998(gynoecy)and TopMark(andromonoecy)as hybridized combination.Genetic map was constructed by Simple Sequence Repeat Markers(SSR)and melon(Cucumis melo L.)genes determined sex expression were located using F2 generation as materials at the same time.The research indicated that a（andromonoecious）,g（gynomonoecious）and gy（gynoecious）were the three genes which determine sex expression of melon.A genetic map of melon included 31 SSR molecular markers and 2 morphological markers were constructed.Besides,two SSR molecular markers related with sex determination were found.The genetic distances were 13.5 cM between MU55491 marker and gene a and 11.6 cM between MU147232
marker and gene gy，respectively.
