title: [The analysis of allozymic variation and genetic diversity in different Prunus mongolica population].
abstract: OBJECTIVE
  To evaluate the allozymic variation and genetic diversity from four wild population of Prunus mongolica.
  
  
  METHODS
  The technique of polyacrylamide gel electrophoresis was used.
  
  
  RESULTS
  The percentage of loci polymorphic (P) was 77.78%. The mean number of alleles per locus (A) was 1.7916. The mean observed heterozygosity per locus ( H ) was 0.4009 and the mean expected heterozygosity per locus (He) was 0.4898. The coefficient of gene differentiation (G(ST)) was 0.0693 which explained that 6.93% of the total genetic diversity was distributed within populations. The gene flow (Nm) was 3. 3575, which indicated the gene flow took place among populations. The fixation index (F) was 0.0896 which indicated a slight excess of homozygote within populations and a little insufficiency of heterozygosity.
  
  
  CONCLUSIONS
  Considering the relatively high level of genetic diversity in Prunus mongolica regenerating in the largest population, we recommend in situ conservation to maintain viable Prunus mongolica populations in their original habitats.
