| Outline of Final Research Achievements |
We have revealed that apogamous fern species, which usually asexually reproduce, can easily hybridize with closely related sexual species and make hybrids. We collected spores from the tetraploid hybrids between triploid apogamous Cyrtomium falcatum and its diploid sexual forms, and cultivated gametophytes generated from the spores. Apogamous gametophytes, which could form next-generation sporophytes without fertilization, and sexual one, which could not, were observed in 1:1 ratio. These results indicate that apogamous reproduction in ferns is controlled by a single DNA region.
