ABSTRACT
Objective To determine the genetic diversity of germplasm resource in Dryopteris fragrans by amplified fragment length polymorphism(AFLP) technique.Methods Forty-six samples from six populations of D.fragrans were analyzed by AFLP DNA markers,and the genetic diversity was evaluated by NTSYS-PC 2.10 and PopGen32.Results The percentage of polymorphic bands(PPB) reached to 76.67%,observed number of alleles(Na) was 1.766 7, effective number of alleles(Ne) was 1.504 6,Nei′s gene diversity index(H) was 0.292 1,Shannon information index(I) was 0.431 6,and genetic differentiation index(Gst) was 0.412 5.Conclusion Genetic diversity is high,gene diversity in populations(Hs) is 0.170 5,and gene diversity among populations(Dst) is 0.119 8.Because of environmental specificity,its resource on the spot should be protected.
