Random amplified polymorphic DNA (RAPD) fingerprints of Pelargonium . DNA aliquots from 13 cultivars of Pelargonium hortorum (lanes a to m), nine cultivars of P. peltatum (lanes n to v), and one individual of the wild subspecies P. peltatum ssp. dibrachya (lane w) were amplified with the arbitrary 10-mer primer OPG-5. RAPD products were separated on a 1.5% agarose gel and stained with ethidium bromide. Positions of size markers (lane S) are indicated in base bairs (bp). N, negative control (no template DNA in the PCR assay). MW, molecular weight.
