| Research Abstract |
The aims of my study are, based on the analyses of the current genetic structure of wasabi and its wild relatives, to reveal the evolutionary history of them and to try to reconstruct of the evolutionary process. Chloroplast microsatellite markers from 10 regions were developed and analyzed. Using them, the genotyping of wasabi cultivars in Japan were successfully performed. It was revealed that artificial disturbance had a large impact on the genetic composition and diversity of wild Eutrema species in Japan.
