title: [Analysis on genetic diversity among wild Dipsacus asperoides by SCoT].
abstract: To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.
