Total 69 random primers were screened out through RAPD （Random Amplified Polymorphic DNA） markers to analyze the genetic bands of 32 Kentucky bluegrass cultivars. A total of 197 bands were amplified from 46 primers of them, among which 195 bands were polymorphic. Each primer could amplify one to nine polymorphic bands with an average of 4.3 being amplified from an average of primer. Based on the similarity coefficient analysis of RAPD results, NTSYS software and cluster analysis by using average UPGMA method, the result showed that 18 of 32 cultivars were in group 1, three cultivars were in group 2, two cultivars were in group 3, eight cultivars were in group 4, and there was only one cultivar in group 5, which was C2.
