Abstract: Octoploid strawberry, Fragaria × ananassa Duch., (2n = 56), pollinated by Potentilla anserina L. (2n = 28) and P. fruticosa L. cv. Golddrop (2n = 14) gave high achene set but germination was low and seedling lethality high in both cases. Most offspring from P. anserina died by 6 weeks with 1% survival of germinating seed at 34 weeks; offspring from P. fruticosa pollination showed gradual mortality with 7% surviving at 34 weeks. Surviving offspring from P. anserina pollinations were either 28 chromosome tetrahaploids (5 plants) or 56 chromosome octoploids (4 plants). Surviving offspring from P. fruticosa pollinations included tetrahaploids (2 plants), octoploid (1 plant), or 35-chromosome pentaploid intergeneric hybrids (9 plants). Tetrahaploids are weak with small leaves and two that have flowered are pollen and pistil sterile.
