[Analysis of genetic diversity among 13 Chinese species of Dendrobium based on AFLP].

Abstract excerpt

Amplified fragment length polymorphism (AFLP) was assessed in 13 Chinese species of Dendrobium. Three primer combinations E+ACT/M+CAC, E+AAC/M+CAC and E+ACA/M+CAC were used for selective amplification. Between 100 bp and 300 bp, a totle of 346 fragments were detected, in which 342 are polymorphic. The rate of polymorphism was 98.8%. The AFLP data were analyzed using Nei & Li similarity coefficient and UPGMA...
