Best practice of such discrimination will be proposed based on genetic diversity. The proposed procedure may serve as an effective means to prevent producers from adulterating domestic rice with imported rice, and boost consumer confidence on domestic agricultural products.&#10;&nbsp;簡單重複序列水稻品種DNA資料庫水稻品種鑑定主成分分析Simple sequence repeatRice DNA profile databaseRice varietyPrincipal Coordinate Analysis
