Breeding of rice varieties that are enriched with essential micronutrients and simultaneously have reduced levels of toxic elements in grains is largely unexplored in rice breeding practice. In this issue of JIPB, Liu et al. (2020) developed two rice lines with a low level of cadmium and simultaneously high levels of zinc or selenium accumulation in the grains, thus providing elite genetic materials for breeding rice varieties that are important for addressing mineral malnutrition and ensuring food safety.

在水稻育种实践中，尚未开发出富含必需微量营养素并同时减少谷物中有毒元素含量的水稻品种的育种。Liu等人在JIPB的这一期中。（2020年）开发了两种水稻中镉含量低，同时锌和硒含量高的水稻系，从而为育种水稻品种提供了优良的遗传材料，这对解决矿质营养不良和确保食品安全至关重要。
