Abstract：Abstract: Cadmium (Cd) pollution in paddy fields leads to Cd accumulation in grains of rice. Long-term con-sumption of Cd contaminated rice is harmful to human health. Therefore, it is of great theoretical signifi-cance and application value to study genetic mechanisms of Cd accumulation in rice and to cultivate low-Cd rice varieties. The characteristics of Cd absorption, transport and accumulation in rice have genetic diversity, though affected by environmental factors. In recent years, great progress has been made in research on the genetic regulation mechanisms of Cd absorption and transport in rice. Many Cd-linked QTLs, transporters and regulatory factors have been identified, and the key role of OsNRAMP5 in Cd absorption and its appli-cation potential in low-Cd rice breeding have been determined. With the development of low Cd molecular markers, novel low-Cd rice germplasm resources have been cultivated. In this paper, genetic mechanisms of Cd accumulation, the progress of low-Cd rice breeding, and the prospect of low Cd molecular pyramiding breeding of rice were reviewed.
