Female varieties of Fragaria X ananassa (Sonja, Freja, Mieze Schilndler, Dir. Wallbaum, Reine des Precoces, Pozdnaya Slodkaya and others) and, tentatively, one female clone, F. virginiana "Scheldon", were pollinated with nineteen Potentilla species in the course of four years (1977-1980). A total of 99194 seeds was obtained, and from them, 739 seedlings (0.75%). After the first year of growth, a mean 24% of seedlings survived (178) Vegetatively mature plants were obtained from the above named octoploid maternal forms (Reine des Precoces excepted) with six Potentilla species (the diploid P. rupestris, P. purpureoides, P. geoides, P. glandulosa and P. fruticosa as well as the hexaploid P. fragiformis). F. X ananassa var. Sonja X P. rupestris was classified as the best combination in producing surviving plants
