Abstract:

Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic diversity of three natural population of Liriodendron chinense. 14 primers generated 235 bands,among which 178 bands were polymorphic. It was indicated that L.chinense had high genetic diversity. 66.97% of genetic variation was observed within populations. The polymorphic bands percentage of three populations(south, central area and north) was 75.74%,83.83% and 75.32%,respectively. Basic data were provided for further studies on the genetic variation,selection and evaluation of L.chinense.

Key words: Liriodendron chinense, genetic diversity, RAPD
