Natural hybridization between Fragaria species has repeatedly been reported, and studies on the hybridization potential between F.×ananassa and its wild relatives have become increasingly important with the outlook for genetically modified garden strawberries. In Europe, a candidate species for hybridization with garden strawberries is the common woodland strawberry (Fragaria vesca L.). Although a previous field survey indicated that the potential for hybridization between F. vesca and F.×ananassa is low, it is not clear whether the lack of natural hybrids is caused by known pre- and postzygotic barriers, or whether hybrid plants lack the fitness to establish in natural F. vesca populations. We grew different F. vesca and F. vesca×F.×ananassa hybrid clones with and without competition in a greenhouse and assessed biomass production, clonal reproduction, and sexual reproduction of plants. While some hybrid clones exceeded F. vesca in biomass production, general clonal reproduction was much lower and delayed in hybrids. Furthermore, hybrids were sterile. These results demonstrate a mechanism by which the general lack of F. vesca×F.×ananassa hybrids in natural habitats can be explained, in addition to the known low hybridization potential between garden and woodland strawberries. We conclude that hybrids have a competitive disadvantage against co-occurring F. vesca plants due to inferior and delayed clonal reproduction, and that the potential for hybrid establishment under natural conditions is low.
