Genetic variation and relationships in genetic resources collections can be assessed using molecular genetic markers. We examined the applicability of the RAPD assay for quick, cost-effective, and reliable use in improving collection management. Fourteen accessions of Brassica oleracea spp. capitata `Golden Acre' (cabbage) were screened using nine decamer oligonucleotide primers. We obtained 110 reproducible fragments, of which 80 were polymorphic, ranging in size from 370-1730 bp. Individual accessions were readily distinguished. A cluster analysis of genetic distances generated by bootstrapping reflected all known genetic relationships, except one. Bulking strategies were also investigated. RAPD markers can be applied to gene bank management to measure variation, identify accessions, and establish genetic similarity at the intra-specific level addressing the needs of both curators and users.
