Multiple variants of ‘Boysen’ have been horticulturally recognized since the cultivar was introduced in 1938. An improved 8-SSR DNA fingerprinting set was applied to ‘Boysen’ and ‘Logan’ variants and their putative parents obtained from private growers and commercial nurseries. A ‘Boysen’ genotype likely to be from the original clone was identified. ‘Boysen’ appears to have resulted from ‘Logan’ × ‘Austin Mayes’. ‘Lucretia’ is not a parent. Continuing work will establish pedigree or relational links for wild and cultivated blackberries.
