Thirty polymorphic nuclear microsatellite loci from black walnut.

Black walnut (Juglans nigra L) is a large tree, native to the eastern United States, that is prized for its high-quality timber and edible nut. Thirty (GA/CT)n nuclear microsatellite markers were identified from black walnut for use in population genetic studies, genome mapping, DNA genotyping of important clones, studies of gene flow, and tree breeding. The markers were polymorphic based on a diversity panel of 10 black walnut individuals from eight Midwestern U.S. states.
