Percentage of polymorphic loci w as 57. 8% . According to the measurement of Shannon index and Nei s index , genetic diversity of Pinus koraiensis main- . , ly distributed within population In th e studied populations of Pinus koraiensis the level of genetic diversity . of PLS was higher than that of PHH and PHL The average genetic similarity within populations w as 0. 927, that among populations was 0. 845. The relative low level of genetic diversity inPinus koraiensis w as largely connected w ith the ser
