| Research Abstract |
In order to clarify key genes for rice domestication, the agronomical effects of non-spreading panicles of cultivated rice were analyzed. Near-isogenic lines for non-spreading panicles in the genetic background of wild rice were subjected to the field experiments. As a result, plants with closed panicles showed significantly reduced seed-shattering and outcrossing rates. These results suggests that a simple morphological change in panicle shape had a large impact on seed-shattering and pollinating behaviors and a strong influence on rice domestication.
