Abstract: Simple Sequence Repeat (SSR) was employed to study the genetic analysis and genetic distance (GD) among 48 clones in Populus L. Sixteen polymorphism markers produced 81 alleles (size ranged from 100-600 bp) totally. GD ranged from 0.061 7-0.530 9 among 48 poplar clones with the average of 0.250 4. GD ranged from 0.148 2-0.274 1 between inter-section and from 0.330 2-0.401 2 between different sections. By cluster analysis, 48 clones were clustered into 5 groups at 0.70, of which the clones divided into 5 section (sect.Leuce; sect.Aigeiros; sect.Tacamahaca; sect.Leucoides and sect.Turanga) clearly. Genetic distance of different section of Populus by molecular method can provide theoretical basis for cross breeding and molecular breeding in poplar.
