Abstract:

An optimization SSR reaction system was established to investigate the genetic diversity of Hyphantria cunea (Drury). A population of Hyphantria cunea in Cangzhou was used to optimize PCR conditions in the SSR system. The results showed that the best condition was 0.40 mmol·L-1 dNTP, 2.5 mmol·L-1 Mg2+, 0.32 μmol·L-1 primers, 1U Taq polymerase, 30~60 ng template DNA in 25 μL SSR reaction system and the optimal annealing temperature of primers was 52 ℃. Genetic diversity of five Hyphantria cunea populations was studied with this SSR reaction system, and the result showed the microsatellite primers were high polymorphic and this system was suitable and stable.

Key words: Hyphantria cunea, SSR, analysis system
