| Abstract: | Rice (Oryza sativa L.) is one of the main staple crops, and the problem of cadmium pollution in rice grain is a serious threat for human health. It is extremely urgent to reduce the risk of cadmium pollution in grain and realize the rice safe production. Screening and breeding of rice varieties with low-cadmium accumulation is one of the economic and effective method to reduce the risk of cadmium pollution in rice. The screening techniques are based on the phenotype and molecular marker. The breeding methods have evolved from conventional breeding to molecular breeding. The techniques of screening and breeding will be becoming more precise, efficient and intelligent, which provide huge impetus for the safe production of rice. This article reviewed the latest researches in the selection of low-cadmium accumulation rice varieties and the creation of low-cadmium materials, and prospected the future development direction of molecular breeding systems with new-technologies, aiming to provide scientific support for ensuring food security and dietary health. |
