Hybrids and Hybridization

Zalewska-GaƂosz, Joanna [1].

The first, molecularly proved, record of Potamgoeton × cooperi (Potamogetonaceae) from Croatia, Southern Europe.

Natural hybridization has been considered as a source of taxonomic complexity in Potamogeton. The identity of plants morphologically intermediate between Potamogeton crispus and P. perfoliatus from recently discovered locality in Croatia, Southern Europe, was investigated with molecular markers. The presence of an additive ITS sequence pattern from two parental species, P. crispus and P. perfoliatus, in the samples studied, proved its hybrid origin and the putative parentage pointed out based on morphological characters. Investigation of rpl32-trnL and rps12-rpl20 intergenic spacers of chloroplast DNA evidenced that P. crispus was the female parent of the newly recorded Potamogeton hybrid. Diagnostic features of P. cooperi × are presented and its distribution is discussed. Sparse records of at least part of the rare Potamogeton hybrid taxa reflect still insufficient state of knowledge on the regional hybrid diversity.
