In our world with a changing climate, an increasingly common tendency can be observed linked to the cultivation of tropical and subtropical plant species both in larger or smaller scale. However, the appearance of these species requires proper preparation, based on economic and ecological considerations, it is necessary to weigh the potential genetic and ecological risks of the cultivation. The subjects of the present study are five New World species (Physalis peruviana L., P.pruinosa L., P. pubescens L., P. ixocarpa Brot., P. philadelphica Lam.) and one species (P. alkekengi L.), which is native in Europe and Asia, as the only member of the genus in the Old World. The growing popularity of the edible species and its appearance in Europe will sooner or later raise the question of whether these geographically separated species are capable of hybridisation or could escape from cultivation or not. The present study attempts to describe the results of the hybridization experiments based on literary sources, supplemented with own results and observations.
