Abstract

Five polymorphic microsatellite markers are described for coast redwood, a hexaploid conifer. Dinucleotide (three), trinucleotide (one) and tetranucleotide (one) repeat loci were isolated from a genomic plasmid library and amplified in a test population of 25 second-growth redwoods. There were three to 11 alleles per locus and observed heterozygosities ranged from 0.00 to 0.80. The nonheterozygous locus (a CTTA repeat) is probably of chloroplast origin and may have potential as a marker for paternal inheritance.
