Intergeneric and reciprocal crosses between Fragaria ananassa and some Potentilla species, have been made for a few years, produced maternal-like progenies. However two hybrid plants were obtained from crosses P. Rupestris x F. Ananassa cv. Ducat.   The morphological characters of these hybrids indicating on participation of male parent are: colour, length and thickness of leaves' and inflorescences' petiols, shape and size of petals.  The hybrid characters were confirmed by RAPD analysis.  A total 23 visible RAPD fragments were produced from which 22 (96%) were polimorphic.  The female parent (F.ananassa cv. Ducat) showed 9 specific bands and 2 of them were in hybrids.  Similarity values indicated that hybrids are more closely related to female (0,72) than to male (0,33) parent.
