There are 8/17 SSR markers revealed polymorphic. Among 42 putative genetic alleles were amplified, of which 32 were polymorphic (accounting for 76.19%). The genetic diversity were highest in Cong Troi population (<em>h </em>= 0.150, <em>I </em>= 0.415 and <em>PPB </em>= 52.95) and the lowest in Hon Giao population (<em>h </em>= 0.115, <em>I </em>= 0.330 and <em>PPB </em>= 47.06). The number of private alleles (<em>Ap</em>) was only found in three populations of Yang Ly (0.059), Cong Troi (0.118) and Chu Yang Sin (0.294). The level of low molecular changes between populations (11.94%) and high among individuals in the population (88.06%) was found. The genetic similarity among <em>Pinus kremfii</em> samples in Tay Nguyen ranged from 59% to 100%. The gene flow (<em>Nm</em>) over all <em>P. kremfii</em> populations per marker was relatively high, ranging from 1,813 to 10,796. Overall, we recommend a combination of conservation for <em>P. krempfii.</em></p> ER -
