Allozyme variation and genetic diversity of Glehnia littoralis populations at the middle of seaboard in China

Genetic variation characters of 19 loci in 8 enzyme systems from 7 populations of \%Glehnia littoralis \%Fr. Schmidt ex Miq. at seaboard of Jiangsu, Shandong and Zhejiang Provinces in China were analysed using vertical slab polyacrylamide gel electrophoresis. The results showed that the average percentage of polymorphic loci is 82.4%, mean allele number per locus 2.77, effective allele number 2.24, and the average fixation index -0.091. There is 80.9% genetic variation within population. The average genetic distances between 7 populations of this species is 0.317. It is indicated that the levels of genetic diversity in \%G. littoralis \%populations are higher.
