China Received 13 June 2005 accepted 10 November 2005 Abstract - Inter-simple sequence repeat polymorphism ISSR and amplified fragment length polymorphism AFLP analysis techniques were used in this study for the genetic fingerprinting and identification of 28 important Chinese poplar accessions. After fingerprinting the genetic relationships among the accessions were determined. Each of three ISSR primers and four AFLP primer pairs produced fingerprint profiles that were unique to each of the accessions studied and thus could be used solely for their identification. In general the molecular data separated accessions from different poplar sections and also distinguished between native and exotic accessions. In conclusion both ISSR and AFLP could be applied to identify large numbers of poplar accessions and could also be used to rapidly determine the genetic relationships among them. Furthermore it is useful to conduct comparative studies with different marker systems when investigating the genetic relationships of poplar accessions. poplar identification genetic relationships AFLP ISSR Résumé - Identification de cultivars de peuplier chinois à l aide de marqueurs ISSR et AFLP et étude de leur relation génétique.
