Lowbush blueberry ( Vaccinium angustifolium , section Cyanococcus A. Gray, Ericaceae) is a unique agricultural crop of northeastern North America in that it is wild in origin. Plants are not sown but have been left to reclaim burned and cleared

There are over 60,000 ha of cultivated blueberries in North America ( Ballington, 2001 ; Trinka, 1996 ), and the United States is the world's leading producer. In a survey of blueberry research and extension scientists in the United States, lack of

Sixty-nine accessions representing wild and domesticated highbush blueberry (Vaccinium corymbosum L.) germplasm were genotyped using 28 simple sequence repeats (SSRs). A total of 627 alleles was detected and unique fingerprints were generated for all accessions. Suspected duplicate accessions of `Coville' and `Ivanhoe' had DNA fingerprints that were identical to `Coville' and `Ivanhoe', respectively. Genetic similarity measures placed wild and cultivated blueberries in separate groups. Northern highbush blueberries grouped among ancestral clones that were used extensively in blueberry breeding such as `Rubel' and `Stanley'. Southern highbush blueberries formed a separate group from northern highbush blueberries. The microsatellite markers used here show excellent promise for further use in germplasm identification, in genetic studies of wild Vaccinium L. populations, and for constructing linkage maps.
