Analysis on Genetic Diversity of Four Morphological Variation Types of Natural Population of Sabina vulgaris in Maowusu Sandy Land

The genetic diversity of four morphological variation types of natural population of Sabina vulgaris in Maowusu Sandy Land was analyzed by use of the Random Amplified Polymorphic DNA(RAPD) technique.201 bands were amplified by seventeen random primers,in which 194 were polymorphic.The data was analyzed with the POPGENE VERSION 1.31 software.The results showed that the genetic diversity of four morphological variation types of Sabina vulgaris was abundant.The percentage of polymorphic loci(PPB) for all types varied from 79.10% to 85.57%.Gst=0.0593,94.07 percent of genetic differentiation were within all variation types.The cluster analysis demonstrated that the genetic charged by growth characteristics of breach was more possible than color.
