Abstract: The AFLP analysiswas conducted in order to investigate the blood relationship among the 107 strawberry cultivars conserved in Beijing, the National Strawberry Germplasm Repository. 10 pairs primers were selected from 64 primer pairs (2 + 2) to amplify the genomic DNAs. Total 581 AFLP fragments were obtained, 412 of them were polymorphic markers. The phylogenetic tree generated byUPGMA method showed the genetic relationship among cultivars identified by AFLP was better identical with their pedigree. AFLP technique was proved to be a very reliable method to study the genetic relationship s of strawberry cultivars.
