| Outline of Final Research Achievements |
In order to figure out the nature of Asian wild rice, Oryza rufipogon, natural wild populations were investigated in three tropical Asian countries, Vietnam, Cambodia and Myanmar. Based on the genetic variation among wild populations using molecular markers, genetic population structures of annual and perennial wild rice were found to vary according to the propagation manners and environmental conditions. Gene flow between wild and cultivated rice was detected using molecular markers on domestication traits. It suggests that frequency of the gene flow is mainly due to the plant distribution conditions.
