Abstract: Cultivated cucumber and its wild varieties , wild Cucumis species ( C. hystrix Chakr. ) ,interspecific hybrids and the BC1S2 , and melon cultivars were used to study the relationship by RAPD markers. 31 arbitrary primers were screened to detected polymorphism among the total 23 cultigens used. Of the 375 sites
produced , 90. 0 % were polymorphic. Each primer amplified an average of 6. 3 fragments. The results from UPGMA cluster analysis suggested that 23 cultigens could be classified into four groups , they are : cultivated cucumber and its wild variety , C. hystrix , C. ×hytivus , and melons.

Key words: Cucumis, Interspecific hybridization, Phylogeny, RAPD
