Abstract:
Genetic diversity and genetic differentiation of Second-generation Seed Orchard of Pinus tabulaeformis Carr.were analyzed by using random amplified polymorphic DNA (RAPD) marker.To better understand their genetic diversity and further utilize them for breeding 120 samples were collected and analyzed using 15 screened RAPD primers.The results showed that the genetic diversity at species level was relatiely high.The results showed that a total of 201 markers from 200 to 1 000 bp were generated and 152 of them（75.62%）were polymorphic markers．Shannon information index (I) was 0.4352 and Nei’s gene diver sity (H) was 0.3821.Using unweightedpair group method with arithmetic average （UPGMA） were classified into 3 groups at level 0.15，result revealed an abundant genetic diversity of Second-generation Seed Orchard of Pinus tabulaeformis Carr.
