Analysis of Genetic Diversity for Camellia meiocarpa Hu. Population in Southwest Area of China by SRAP

The genetic diversity of 180 samples from six populations of Camellia meiocarpa Hu.was analyzed by SRAP markers.Nine ideal primer combinations with polymorphism were selected from 87 SRAP primers,and they were applied to the amplification which produced 184 bands,in which 184 bands were polymorphic and polymorphic loci ratio reached 100%.The average effective number of alleles was 1.776 3,the diversity index of total Nei gene in 180 samples of Camellia meiocarpa Hu.was 0.432 8,and the average Shannon's information index was 0.623 3,so they indicated that population of Camellia meiocarpa Hu.had abundant genetic diversity,the genetic diversity mainly distributed within population,and the variation between populations was relatively small.Meanwhile,the conservation strategies for genetic diversity of amellia meiocarpa Hu.were put forward.
