Abstract:
Dabie Mountains provides unique habitat for Rhododendron resources,and is an important diversity distribution center of Rhododendron genus in China.In this study,three Rhododendron species,including Rhododendron molle (Blume) G.Don, Rhododendron fortunei Lindl.,and Rhododendron mariesii Hemsl.et Wils.,were selected for genetic diversity and genetic structure analysis with 9 microsatellite markers.The results showed that 45 alleles were obtained,and observed number of alleles per locus ranged from 3 to 7.Shannon index ranged from 0.87 to 0.91.Moreover,HO and HE were in the ranges of 0.523-0.651 and 0.517-0.536,respectively.The mean value of Fit and Fis were 0.075 9 and -0.173 3,respectively,indicating inbreeding took place in all three populations.The average gene flow at each locus was 0.927 0.In the cluster analysis,R.molle was clustered with R.fortunei,inferring closer relations between these two species.This study would lay the foundation for the evolutionary study of Rhododendron species.
