Abstract: Allozyme electrophoresis was applied to the genetic diversity analysis of wild Camellia japonica populations on Qingdao off shore island——Changmenyan Island, Daguan Island and of Putuo Mountain in Zhejiang Province, as a comparison, two cultivated camellia populations in Qingdao Botanical Gardens and in Hangzhou Botanical Gardens were analyzed. The result showed that the genetic diversity within island camellia population is high, the mean number of alleles per locus is 2.3; 83.3% of loci are polymorphic on average per population; the mean observed and expected heterozygosities are 0.245 and 0.320 respectively. The result suggested strategies for the conservation of camellia in Qingdao. Allozyme phenotypes of different morphological types were compared in order to find some relationships between morphological variation and allozyme diversity.
