Molecular genetic marker-based approaches to the verification of lilac Syringa vulgaris L. in vitro germplasm collections

RAPD analysis was used to verify the varieties in an in vitro germplasm collection of lilac Syringa vulgaris L. RAPD patterns were obtained with 16 decanucleotide primers for 46 accessions (microclones and corresponding reference varieties). The RAPD patterns of a microclone and the corresponding reference variety often differed in composition; consequently, it was infeasible to verify the accessions by direct comparison of the RAPD patterns. Hence, evaluation of the relative genetic distances between accessions (microclones) and known varieties was proposed as a method to verify lilac in vitro germplasm collections.
