RAPD analysis on genetic differentiation of Hyphantria cunea populations.

Abstract

Abstract: The genetic diversity and UPMGA clustering of nine Hyphantria cunea geographic populations were analyzed by random amplified polymorphic DNA (RAPD) technique. A total of 191 bands were obtained from 25 effective primers, of which, 158 bands were polymorphic, accounting for 82.72%. The genetic distance index of the populations was 0.2043-0.5108, and the similarity coefficient was 0.4892-0.7957. The nine populations could be divided into three groups, i.e., Liaoning and Shandong group, Beijing and Tianjing group, and American group, suggesting that the genetic differentiation of H. cunea populations was correlated with geographical location.
