摘　　要：硒是人体必需的微量元素,中国大部分地区都为缺硒地带。富硒大米是人体补充硒元素的最简便的途径之一,但是富硒对水稻加工品质的影响不明。从国际水稻所引进了一套籼稻微核心种质,对其中25份种质资源在富硒条件下考察了加工品质。结果显示,不同品种对富硒的反馈表现不同,富硒分别提高了8个品种的糙米率、12个品种的精米率和10个品种的整精米率,同时降低了7个品种的糙米率、8个品种的精米率和8个品种的整精米率。富硒对糙米率和整精米率的提高和降低作用相当,能提高大部分品种的精米率。研究结果将为富硒大米育种和生产提供理论指导。Selenium, an essential element for our body,is lack at most area in China. Selenium-rich rice is the easiest way to supply Selenium, but the effect of Selenium-rich on rice milling quality is still unknown.In this paper,25 indica varieties introduced from International Rice Research Institute were planted at Selenium-rich and CK conditions and their milling quality were tested. The results showed that different varieties had different response towards Selenium-rich.Selenium-rich improved the brown rice rate,milled rice rate and head rice rate of 8,12,and 10 varieties, respectively,while the brown rice rate,milled rice rate and head rice rate of 7,8,and 8 varieties decreased, respectively. it had the same effect on brown rice rate and head rice rate,while significantly improved milled rice rate. The results provided the guidelinet for Selenium-enriched rice breeding and theoretical basis for Selenium-enriched rice production.
