title: [Analysis of genetic diversity and genetic relationships of Lonicera macranthoides cultivars].
abstract: OBJECTIVE
  To study genetic diversity and genetic relationships among Lonicera macranthoides cultivars.
  
  
  METHODS
  Five cultivars were estimated by ISSR and SRAP. The data of amplified bands were analyzed by Treeconw software. The system diagram of genetic relationship was built by UPGMA.
  
  
  RESULTS
  Twenty ISSR primers amplified 186 bands with 103 (54.63%) polymorphic bands and 58 SRAP primer combinations amplified 591 bands with 347(55.46%) polymorphic bands. Genetic distance ranges were 0.058 4-0.230 8 (by ISSRs) and 0.1071-0.2611 (by SRAPs). Both ISSR and SRAP analyses revealed a middle level of genetic diversity in L. macranthoides cultivars. The dendrograms based on SRAP and ISSR markers were not all the same.
  
  
  CONCLUSIONS
  The genetic diversity of L. macranthoides cultivars is middle. ISSR and SRAP markers can be effectively applied to genetic analysis in L. macranthoides cultivars.
