Abstract:
Fifteen species and eight cultivars of the section Pelargonium (DC.) Harv., two species of the section Ligularia (Sweet) Harv. and three species of the section Cortusina (DC.) Harv. were tested for genetic distance to predict successful combinations of interspecific crossings. 156 randomly amplified polymorphic DNA (RAPD)-bands and 485 double primer RAPD-bands were used for distance analysis. Combined with information on the ploidy level, species were clustered in the expected sections except Pelargonium hirtum (Burm. f.) Jacq., which clustered with the species of the section Cortusina. Different accessions of the same wild species showed a high conformity (67–98 %) comparable to the cultivars (66–70 %).
