Abstract: Xinjiang Hami melon, with independent and different genetic background of cantaloupe, is a unique cultivar in China. A set of populations were developed from a cross between the cantaloupe [ Cucumis melo L. ssp. melo convar. cantalupa ( Pang. ) Greb. ] and the Xinjiang Hami melon [ Cucumis melo L.
ssp. melo convar. ameri ( Pang. ) Greb. ]. Simple sequence repeat ( SSR) markers were used to construct permanent genetic map with the F2 S6 populations. The map consisted of 22 linkage groups, contained 201 SSR
markers and 1 morphological trait, it spanned a total genetic distance of 977.153 cM with an average map interval of 4.837 cM between two markers. Seventeen linkage groups in the map were collinear with cantaloupe genetic map, 46 SSR markers were common in two maps. The construction of Xinjiang Hami melon SSR map laid foundation for the continuation of the international integration of melon common genetic map and comparative study.

Key words: melon, Cucumis melo L., SSR marker, genetic map, comparative mapping
