Abstract:
A hybrid of P. praelongus and P. lucens (P.×jutlandicus) was found in an outdoor germination test in 2013–2015, which confirmed existence of spontaneous hybridization of the pondweed species present in the ponds below Plešivec in the Kokořínsko Protected Landscape Area in the Czech Republic. Seedlings of P. ×jutlandicus were different from those of P. praelongus and the speed of their growth was higher. P. ×jutlandicus has not been found in natural sites in the Czech Republic yet. The Czech locality is the third one of this rare hybrid worldwide and the first one with a molecular proof.
