According to the history, Champa rice was introduced to China at early Song Dynasty about 1000 years ago. Champa Kingdom located in central Vietnam in current days. According to the history, compared with the Chinese rice at that time, these Champa rice had longer panicle, without awn, less difference in grain size, could grow well in marginal land, drought resistant and not sensitive to photoperiod. In this study, we'd like to reveal if the Champa rice is indica type or Aus. Three land races from central Vietnam and 7 Taiwan land races with the word "Champa" as the name were subjected to whole genome sequencing.
