Abstract:

Genetic diversity and differentiation of four natural populations of Quercus mongolica in Northeast China were studied with the method of RAPD.Through the amplification with 48 random primers,344 repeatable loci were detected and 245 loci were polymorphic.Percentage of polymorphic loci was 71.22%.According to the measurement of Shannon index,genetic diversity of Quercus mongolica was on relative high level and genetic variation mainly distributed within population (64.50%).In the studied populations of Quercus mongolica,the level of genetic diversity of OLJ was the highest,that of OHH was the lowest, and that of OSZ and OHL were the middle.The average genetic distance within populations was 0.0962,that among populations was 0.1290.Abundant genetic diversity of Quercus mongolica assured the steady existence and development of its populations.
