Abstract

We report RAPD variation in four size-classes of Metasequoia glyptostroboides plantations in Shanghai. Seven primers produced 48 discernible DNA fragments with 46 being polymorphic. The mean percentage of polymorphic loci (P₉₅) was 84.9% (ranged from 81.3% to 87.5%). The mean number of alleles per locus (A) ranged from 1.57 to 1.65 with a mean of 1.60. The mean heterozygosity (H_e) was 0.3502 (0.3338-0.3663). These data were higher than the estimates of a collection of individuals from natural populations (LI et al., 1999). Little differences were observed among size-classes and the G_ST was 0.097, indicating that M. glyptostroboides trees planted recent decades were highly similar in genetic composition.
