硒是环境中重要的生命微量营养元素之一,人体和动物所需的硒主要由植物从环境中摄取。本文对水稻硒含量的基因型差异、硒与环境条件的相互作用及富硒水稻种质的鉴定与创新进行了综述,并探讨了水稻硒含量的遗传机理及生物强化育种的内容和方向。 Selenium is one of the important micronutrients in the environment. The selenium needed by human beings and animals is mainly taken up by the plants from the environment. In this paper, the genotype differences of selenium content in rice, the interaction between selenium and environmental conditions and the identification and innovation of germplasm of selenium-enriched rice were reviewed. The genetic mechanism of selenium content in rice and the content and direction of biofortification breeding were discussed.
