摘要： Our studies indicated that Cucumis hystrix Chakr. (2n = 2x = 24) is the first wild Cucumis species with Asiatic origin with a base chromosome number x = 12. Randomly amplified polymorphic DNA (RAPD) markers were used to study the taxonomic placement of C. hystrix and its interspecific hybrid with cucumber. Thirty-one accessions were clustered into two main groups (CS and CM). The successful production of the amphidiploid (2n = 4x = 38) from the cross between C. hystrix and C. sativus and subsequent chromosome doubling, provided us with an effective way of investigating the relationship between Cucumis species with two different basic chromosome numbers.
