The physical locations of 45S rDNA and 5S rDNA and karyotype analysis were carried out by means of fluorescence in situ hybridization in Citrullus lanatus、Momordica charantia L.and Siraitia grosvenorii(Swingle) C.Jeffrey.The results showed that two pairs of 45S rDNA and one pairs of 5S rDNA signals were detected on chromosomes of Citrullus lanatus and Momordica charantia L.and three pairs of 45S rDNA and one pairs of 5S rDNA loci were located on chromosomes of Siraitia grosvenorii(Swingle) C.Jeffrey.By comparing the physical location and distribution of 45S rDNA and 5S rDNA on chromosomes
the relationship among some species of Cucurbitaceae and the taxology status of Siraitia grosvenorii(Swingle) C.Jeffrey were discussed.
