Abstract:
Objective To study the genetic diversity of germplasm resources for Potentilla discolor.Methods Twelve species of germplasm resources for P.discolor were analyzed by ISSR molecular markers.To make up the systematic diagram of genetic relationship by POPGENE 1.32 software,cluster by UPGMA method,and establish the dendrogram.Results A total of 128 ISSR bands were scored for 12 primers,among which 101 were polymorphic bands.The average percentage of polymorphic bands was 78.91%.Genetic similarity coefficient was changed from 0.179 2 to 0.632 5.By cluster analysis,the geographical distribution is mutually related to the relationship of germplasm resources for P.discolor and it was also showed some of P.discolor from the same region were in the same group which presented the rule of geographical distribution in the tested materials.Conclusion The diversity level of the different germplasm resources for P.discolor higher and the relationship of P.discolor correlates with the geographical location in some way.
