Random amplified polymorphic DNA markers were used to measure genetic diversity and genetic structure of 150 individuals from 5 natural populations of Carya cathayensis. 252 loci were identified from 20 RAPD primers, out of which 168 loci were polymorphic and accounted for 66.7% of the total genetic diversity at species level.
