Abstract: Deficiency of trace elements nutrient is very prevalent in the world population. Under this situation, functional rice breeding for human micronutrients perspective has been the hot spot among international rice researches. In this paper, current researches on the genetic difference and environment influence of rice trace elements content, especially on the inheritance, genetice relationship and molecular mechanism of rice trace elements content, and the identification, screening and prebreeding of rice germplasm with high trace elements content were reviewed. The strategy of related researches on functional rice for high trace elements content was discussed furthermore.
