A contribution to the systematics of the genus Tilia with respect to some hybrids by RAPD analysis

Abstract: The putative hybrid character of two Tilia varieties selected as avenue trees (‘Szent Istvan’ and‘K3’) should be clarified for further breeding activities. Their ancestor species should be identified by a genetic comparison with reference material (Tilia cordata, T. platyphyllos, T. dasystyla, T. × euchlora, T. × europaea and others). RAPD marker data were evaluated by UPGMA cluster and neighbour-joining analysis. The genetic comparison of the two selected clones with the collection of reference material offers insights into some systematic relationships within the genus Tilia. It was supplemented by a critical discussion of methods of RAPD data evaluation for taxonomic purposes.
