Molecular Polymorphic Analysis for Different Geographic Provenances of Chinese Fir
不同地理种源杉木的分子多态性分析

Genetic diversity of 24 geographic provenances of Chinese fir(Cunninghamia lanceolata) was analysed by ISSR(Inter-simple sequence repeat) markers.Twenty-two primers were screened from 100 ISSR primers.188 DNA bands were amplified from 24 provenances of Chinese fir,173 bands of which belonged to polymorphic bands,account for 92.0%.The effective number of alleles(Ne) was 1.3408,Nei's index of genetic diversity was 0.2154 and Shannon's index of polymorphic information was 0.3458.It indicated that the different...
